Circuit breakers, electrical circuit breakers, circuit breakers are the ability to close, conduct, and interrupt power under normal circuit conditions, and can close, conduct, and interrupt power under abnormal circuit conditions within the prescribed time switching means, divided according to their use of the circuit breaker and low-voltage circuit breaker High voltage circuit breaker, high and low demarcation vague, generally referred to as high voltage electric 3kv above.Ezitown has different voltage from 12v dc to 415v ac, different currents from 1A to 1250A, different breaking capacity 3kA to 50kA, different pole number 1/2 pole up to 4pol.din rail mounting and pluggable mounting, Pannelmontage etc.
