Complementary Technical Information. Isolation function Isolation functions of all the circuit breakers as per IEC097/EN097; Isolating position of contactors is at 0 (OFF) status; The operating handle will correctly indicate the status of 0 (OFF), only if the contactor breaks; Padlocks could be mounted after the contacts breaks; Operation of isolation functions will realize following points: Contacts operation correctly indicates operating reliability of interior mechanism; No residual current; Higher impulse withstands voltage for terminals at the power supply side and onload side.. Currentlimiting.. Currentlimiting capacity The currentlimiting capacity of a circuit breaker is its aptitude to limit shortcircuits current. By occurring of shortcircuit, the breaker is able to limit I t in time so as to protect circuits and switchgear at downstream. The exceptional limiting capacity of TPact series is due to the rotating doublebreak technique, which is characterized by very rapid natural repulsion of contacts and the appearance of two arc voltages in series with a very steep wave front. a. Exceptional currentlimiting capacity is able to greatly reduce power caused by fault current so as to enhance breaking capacity of breaker to Ics=0%Icu; b. The capacity has greatly released damages, which shortcircuit current lay to apparatus; c. The capacity has greatly lowered temperaturerise so as to lengthen service life of the cable; I d. The capacity has greatly reduced power so as to lessen distortion of contacts and bus bar; Prospective current peak e. The capacity has greatly decreased interruptions to apparatus nearby... Currentlimiting curves The currentlimiting capacity of a circuit breaker is expressed by two curves which are the prospective current and the actual shortcircuit current. Actual Thermal stress (A S), i.e. the energy dissipated by the shortcircuit current in a conductor current peak with a resistance of Ω. The table below indicates the maximum permissible thermal stresses for cables depending t on their insulation, conductor (Cu or Al) and cross section area (CSA). CSA values are given in mm and thermal stresses in A S.

33 TPact Moulded Case Circuit Breakers CSA(mm ) PVC Butyl EPR Cu K= Al K=7 Cu K= Al K=87 Cu K= Al K= CSA(mm ) PVC Butyl Cu K= Al K=7 Cu K= Al K=87 Cu K= EPR Al K= K is quoted from GB00 Rules for Lowvoltage Power Distribution Design Example: a. What is the actual current when a prospective shortcircuit current of ka rms (peak value=7ka) comes through the currentlimiting operation circuit breaker at upstream of TPact R Answer: the peak value=ka; (for details, refer to currentlimiting curves) b. Is a Cu/PVC cable with a CSA of mm adequately protected by a TPact S circuit breaker Answer: the table above indicates that the permissible thermal stress is. A S at the point where a TPact (Icu=0kA) is installed, and the shortcircuit current is limited within the range of. A S, therefore the cable could be protected.
