Technical specifications The electronic overcurrent release consists of a separate and interchangeable unit, which is supplied with the VT5 7- AA.-0AA0 switching unit. By exchanging the overcurrent release, the range of the circuit breaker s rated current can be easily changed. Releases for the VT5 7-AA.-0AA0 switching unit are produced in four current values n = 0, 00, 2 and 0 A. ncluding their adjustment, the releases cover rated currents ranging from 2 to 0 A. Depending on the needs for adjusting the release s tripping characteristics to the protected device and to the variability of the characteristic with regard to selectivity, the following release devices are available: ETU DP They have one type of characteristic with adjustable and m. ETU MP They have more kinds of characteristics with adjustable, t r and m. ETU UP They have universal characteristics, with the greatest variability in adjustment:, t r, mv, t v and m. ETU DP, MP and UP Proper functioning of releases does not depend on the form of current in the main circuit. The function of the release is supported by a microprocessor, which processes a sampled signal of the power circuit and recalculates it to obtain an rms value. Therefore, the releases are suitable for protecting circuits where the sinusoidal current is distorted by high harmonics (e.g. circuits with controlled rectifiers, power factor compensators, pulse loading, and the like). All the releases protect a circuit against short-circuiting and overloading. Setting of selective cascading of circuit breakers is especially enabled by the ETU UP release. Tripping characteristics of the releases are independent of the ambient temperature. The releases are affixed to the switching unit by two bolts. The translucent cover over the adjustment controls can be sealed. Adjustment of tripping characteristics for release ETU DP and MP The tripping characteristics of the overcurrent releases are defined by standard EN 0 947-2. The characteristics are adjusted in two zones using latched switches on the overcurrent release unit: - is a zone of low overcurrents and includes the area of thermal protection. - is a zone of high overcurrents and includes protection against ultimate short-circuit currents. ETU DP t t NSO0_00454 t r i.ndependent release (thermal) The dependent release ETU MP is adjusted using two switches, and t r. The first of these, the switch, is used to adjust the circuit breaker s rated current. The characteristic moves on the current axis. By turning the other switch (t r ), the time is adjusted after which the circuit breaker will trip while passing through 7.2. The tripping characteristics thus move on the time axis. Using the tr switch, it is possible to set a total of 8 characteristics. Four characteristics are available for motor protection. Breaking times correspond with the release class A,,, 0. By changing t r it is possible to select the characteristic according to the required motor starting (light, medium, heavy or very heavy starting). For protecting transformers and lines, 4 characteristics can be set. t is not possible to turn the device back on right after the dependent release has been actuated and circuit breaker tripped. The release must be allowed to cool off, because it has a thermal memory. The memory can be disabled by turning the restart switch from the normal T t position to the T 0 position. The dependent release remains active, and only its thermal memory is inactivated. The thermal memory should be used only in justified cases, and with the knowledge that there could be rising temperature in the protected device with repeated tripping. The dependent release ETU DP is adjusted using one switch. Using the switch, the circuit breaker s rated current is adjusted, with the characteristic moving on the current axis. By means of its internal circuitry, the release is set to one type of characteristic, TV. 2. ndependent instantaneous release (short-circuit trip) The independent instantaneous release in designs ETU DP and MP is adjusted using one m switch. The m switch is used for setting up the short-circuit current that, upon its being reached or exceeded, causes instantaneous tripping of the circuit breaker. Regulation of the short-circuit release takes in settings for the characteristic appropriate for protecting lines and motors. The wave form of the tripping characteristics is adjusted using latched switches on the release s front panel according to the needs of the protected device. A visual demonstration on setting the tripping characteristic can be found in the SMARS design. i NSO0_00 ETU MP Based on Siemens Catalog V - 8 Page of /5
Tripping characteristics of ETU DP and MP releases with load The tripping characteristics from the cold state indicate the tripping times during which it is assumed that, up to the moment when an overcurrent develops, no current is flowing through the circuit breaker. The tripping characteristic tripped from warm state indicates the tripping times during which it is assumed that, before the moment when an overcurrent develops, current is flowing through the circuit breaker. Characteristics of electronic releases are independent of the ambient temperature and are plotted in a cold state. Digital releases enable simulation of a release in warm state. The tripping times become shorter in a steady state, as shown in the following diagram. The steady state is a period during which the characteristic does not change. f the circuit breaker is loaded with a reduced current for at least 0 minutes, the tripping times will be cut by a half. f the load is less than 70% of, the tripping time does not become shorter. k [-].0 0. NSO0_00455 Thermal standstill time of the characteristics For all kinds of characteristics t r the thermal standstill time for ETU DPand MP releases is t u 0 min. During this time, the short-circuit tripping time t v is cut short from the cold-state characteristic by the coefficient k. The real tripping time is t s = k. t v Example: The shortening constant can be read from the graph. With steady current 85% of the real tripping time will be shortened to: t s = 0.74. t v k [ ] time shortening coefficient [A] adjusted rated current of the overcurrent release t v [s] tripping time of the release derived from the characteristic t s [s] real tripping time of the release tripped from warm state t u [s] standstill period for particular characteristics are set by the manufacturer = min Restart = T (t) m = min t r = TV, min 0.4 T 0.0 0 70 80 90 0 [%] Tripping time shortening ETU DP, MP with load T - When tripping from the release s warm state, the tripping time of the characteristic is cut short during the standstill time t u by coefficent k. ^ Based on Siemens Catalog V - 8 Page 4 of /
Tripping characteristic adjustment, trip unit ETU UP t NSO0_0045 S t r sd 2 t OFF 2 t ON t sd i The tripping characteristic of overcurrent releases is defined by standard EN 0 947-2. The characteristic is adjusted in three zones using latched switches on the overcurrent release unit: - is a zone of low overcurrents and includes the area of thermal protection. S - is a zone of medium overcurrents and includes long-distance short-circuit protection for lines. ntentional delay in tripping of these low short-circuit currents can be used to achieve selectivity of protective devices. This type of delay can be set only in self-contained releases (full version). - is a zone of high overcurrents and includes protection against ultimate short-circuit currents without time delay. 2 t - Characteristic setting in ON position represents a constant value of energy passed through. f fuses are used as protective elements for outgoing branch feeders, it is possible to adjust the selective part of the characteristics to better suit the shape of the fuse characteristics.. ndependent release (thermal) The dependent release ETU UP is adjusted using two switches, r and tr. Using the first switch, r, the circuit breaker s rated current is adjusted. The characteristic is moved on the current axis. Turning the second switch, tr, adjusts the time after which the circuit breaker will trip while passing through 7.2 r. The tripping characteristic thus moves on the time axis. Using the tr switch, a total of 8 characteristics can be set. Breaking times correspond with the release class A,,, 0. t is not possible to turn the device back on right after the dependent release has been actuated and circuit breaker tripped. The release must be allowed to cool off, because it has a thermal memory. The memory can be disabled by turning the restart switch from the normal Tt position to the T0 position. The dependent release remains active, and only its thermal memory is inactivated. Switching off the thermal memory should be used only in welljustified cases, and with the knowledge that there could be rising temperature in the protected device with repeated tripping. 2. Delayed independent release S The delayed independent release has the function of a delayed short-circuit release. t is used to set up a selective cascade of circuit breakers. t is set up using specifications sd and t sd. sd is an n-multiple of current ( sd = n ). t is a short-circuit current that, within the span of sd to i, will trip the circuit breaker with delay t sd, where t sd is a delay set up for switching off the release. The delayed independent release actuates the circuit breaker if the current in the circuit reaches at least the preset n-multiple and lasts at least the preset delay time t sd. The independent release can be disabled by setting the parameter n ( sd = n ) into the position. Parameter t sd can be set to values with respect to the energy that passed through l 2 t (switch position l 2 t on). The preset time values are then applicable for currents more than x current. Tripping times of k-multiples of for k < are defined as follows: t = t v ----- 2 k. ndependent instantaneous release The independent instantaneous release has the function of a short-circuit release. t is set up only on parameter i. i is shortcircuit current that, upon its being reached or exceeded, causes the circuit breaker instantaneously to switch off. t is set up directly in ka on the release. The wave form of the tripping characteristic is adjusted using latched switches on the release s front panel according to the needs of the protected device. A visual demonstration on setting the tripping characteristic can be found in the SMARS design. Based on Siemens Catalog V - 8 Page 5 of /7

Characteristics of electronic releases are independent of the ambient temperature and are plotted in a cold state. Digital releases enable simulation of a release in warm state. The tripping times become shorter in a steady state, as shown in the following diagram.

During this time, the short-circuit tripping time t v is cut short from the cold-state characteristic by the coefficient k. The real tripping time is t s = k. t v Based on Siemens Catalog V - 8 Page of /8
ETU DP-Distribution Protecting lines and transformers The VT9 5..-AC00 release is intended for VT5 7-AA.- 0AA0 switching unit. The operation of the release is controlled by a microprocessor. The release is outfitted with a thermal memory that can be disabled by turning a switch on the front panel from position T (t) to position T (0). After disabling the thermal memory, the thermal release remains active. A practical advantage of the release is a specially designed tripping characteristic that provides for optimal exploitation of transformers up to.5 n. Another advantage of this release is the simple adjustment of the tripping characteristic. Set-up includes only rated current and the tripping level of the short-circuit release.

ETU MP-Motors Direct protection for motors and generators Possibility for protecting lines and transformers The VT9 5..-AP00 release is intended only for VT57-AA.- 0AA0 switching unit. The operation of the release is controlled by a microprocessor. The release is equipped with a thermal memory that can be disabled by turning a switch on the front panel from position T (t) to position T (0). After disabling of the thermal memory, the thermal release remains active. A partical advantage of the release is a specially designed tripping characteristic that provides for optimal exploitation of transformers up to.5 n. A of 8 characteristics can be set on the release. From these, in mode M there are 4 characteristics for motors protection and another 4 characteristics in mode TV for protecting transformers and lines. The shape of each characteristic can be changed using a selector switch. When one or two phases fail, in the M-characteristic mode, the switch will open with a 4 s delay (so-called undercurrent release). Another parameter for adjusting the release is rated current, which is adjusted in a range of 0.4 to.0 of n and the shortcircuit tripping level. The reaching of 80% and % of is indicated by ED diodes on the front panel denoted as > 80% of and > % of.
