Q:Leakage circuit breaker is not on, how to do
Disconnect all electrical appliances from the line; Adjust the switch of all the lamps to the open position; (the lamp is not energized)
Q:What is the capacity of the circuit breaker
The breaking capacity of the high-voltage circuit breaker is the same as that of the rated breaking current
Q:Circuit breaker main circuit control power, how to wiring?
In use, the circuit breaker should be cut off the capacity of the installation should be greater than the maximum short circuit capacity
Q:Is the zero line going through the circuit breaker?
Three-phase four-wire zero line is absolutely not allowed to go through the circuit breaker, because the zero line is broken, the line of all 220V appliances will withstand 380V line voltage and burned.
Q:Do you have a circuit breaker in the circuit?
that your electrical equipment is a three-phase motor, if the line has a phase failure such as ground fault, etc.
Q:How to look at the circuit breaker capacity is how much?
but the circuit is not broken, must be arc to completely disconnect the circuit current, so the circuit breaker circuit is completely broken circuit called shut-off.
Q:The specific function and operation mode of the auxiliary switch on the circuit breaker switch
High-voltage circuit breakers generally have a number of auxiliary contacts, their on-off and circuit breaker main contact the same (or vice versa), so the secondary circuit
Q:How is the total switch breaker in the distribution box correctly
protection current in the grid after the protection, then the command will be the leakage protector trip occurs when the control of the main circuit breaker trip
Q:Circuit problem! Hurry Miniature Circuit Breaker!
such as the access line loose, due to contact resistance becomes larger, will cause heat to make the circuit breaker malfunction.
Q:What is the specific function of the auxiliary switch on the circuit breaker switch?
Used to control, protect, adjust, measure and monitor the parameters of the circuit and the working conditions of each component.
