Nader Circuit Breaker

Voltage level from the circuit breaker to points: low-voltage circuit breakers, high voltage circuit breakers; power points from nature: AC circuit breakers and DC circuit breakers. From the interrupter structure and principle point: air circuit breakers, oil circuit breakers, sulfur hexafluoride cir...

Shunt trip coil voltage AC and DC types, voltage magnitude various voltage levels. DC24V power source for a fire when the fire power cut by the shunt trip coil power supply is a most convenient and simple. Shunt trip coil is energized only for a short time, over time to burn; so in the control loop i...
