WebThe main function of a circuit breaker is to open under a fault condition. The speed of the contact opening is critical to minimizing the damage to the breaker and the equipment it feeds. The time between the impulse to actuate the trip coil and the actual opening of the circuit breaker indicates how quickly the circuit breaker operates.

WebFeb 24, 2012 · For below 400 KV systems, the circuit breaker is designed to withstand 10% above the normal system voltage. For above or equal 400 KV system the insulation of circuit breaker should be capable of withstanding 5% above the normal system voltage. That means, rated voltage of circuit breaker corresponds to the highest system voltage. http://www.eaton.eu/ecm/groups/public/@pub/@electrical/documents/content/ct_129998.pdf small softbox for strobe
