Analysis Of Operating Short-circuit Breaking Capacity Of Low-voltage Pole-mounted Circuit Breakers

The operating short-circuit breaking capacity (Ics) of Lv Pole Mounted Circuit Breakers refers to the short-circuit current that can be connected and disconnected under certain test parameters (voltage, short-circuit current and power factor) and through a certain test procedure. After this connection and disconnection, it must continue to carry its rated current breaking capacity.
