Currentlimiting capacity he currentlimiting capacity of a circuit breaker is its aptitude to limit shortcircuits current. y occurring of shortcircuit, the breaker is able to limit I t in time so as to protect circuits and switchgear at downstream. he exceptional limiting capacity of NM 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... Currentlimiting curves he currentlimiting capacity of a circuit breaker is expressed by two curves which are the prospective current and the actual shortcircuit current. hermal stress (A S), i.e. the energy dissipated by the shortcircuit current in a conductor with a resistance of Ω. he table below indicates the maximum permissible thermal stresses for cables depending on their insulation, conductor (Cu or Al) and cross section area (CSA).

Cascading. Definition of Cascading. Currentlimiting technique has been adopted for cascading to install downstream circuit breaker with lower breaking capacity (cheaper circuit breakers) at the given point of circuit, and upstream NM(S) circuit breaker operates to limit shortcircuit current. Under the operation of cascading network, circuit breaker with lower breaking capacity compared with prospective shortcircuit current at the given point could operate under normal shortcircuit status. As the shortcircuit current will be limited by upstream circuit breaker with currentlimiting operation, cascading network is applicable to all the power distribution apparatus protection at downstream.. In addition, cascading operation is not restricted to operation of two switches in serial, but is applicable in various electric networks, as well. Application of cascading. hrough the application of cascading, connected apparatuses could be installed in different switchgears to realize normal operation. herefore, cascading, in common, refers to various combination of circuit breakers installed at the given point of which the breaking capacity is lower than prospective shortcircuit current. And breaking capacity of upstream circuit breakers should be equal to or higher than prospective shortcircuit current at the installed point to protect apparatus at downstream. Cascading application is in conformity with IEC097 standards.

Protection discrimination(selectivity) Protection discrimination is a must factor in lowvoltage power distribution design so as to ensure reliability and continuity for users' electricity utilization. Whenever there is fault occurring in the electric network, the upstream breaker where the fault is occurring breaks. Protection discrimination could be clarified into kinds: otal protection discrimination, partial protection discrimination and no protection discrimination(refer to fig aside): otal protection discrimination: For all kinds of current where the faults occurred, including the overload current and nonresistance current, breaker D breaks and breaker D keeps making status. Partial protection discrimination: For a much lower current compared with where the fault occurred (the limit value of protection discrimination), breaker D breaks and breaker D keeps making status (total protection discrimination). When the fault current is lower than limit value of protection discrimination, the upstream and downstream breakers are applicable to protection discrimination; when the fault current exceeds limit value of protection discrimination, the upstream and downstream breakers are not applicable to protection discrimination (no protection discrimination). And both of the breakers of D and D break.
