Q:How to choose a circuit breaker for home and small office circuits

When overload or short circuit, the small circuit breaker handle, the leakage attachment handle does not move. When the leakage occurs, both handles are activated.

Q:The specific function and operation mode of the auxiliary switch on the circuit breaker switch

can be through the auxiliary contact circuit breaker Split position, to achieve automatic control (even jump, BZT, mutual latch, start and stop protection, and so on).

Q:Home circuit breakers and how much air is open

the principle of air switch, the function of the general situation for the customer matching distribution box in the process, should be in a small lighting, socket, air conditioning large matching principle

Q:Why the first break circuit breaker, after the isolation switch off it?

when the circuit breaker is broken, the circuit has no current, pull the switch will not produce arc, There will be an accident.

Q:Frame circuit breaker, molded case circuit breaker difference

but many people are not very aware of the differences between the two, in the purchase time often appear indecisive situation.

Q:Leakage circuit breaker is not on, how to do

Close the total circuit switch; (line power state) Then separate the shunt switch one by one

Q:Circuit system diagram and circuit breaker connection

, but in the maintenance can manually disconnect the circuit to ensure that maintenance personnel personal safety

Q:How is the circuit breaker different from the air circuit breaker?

Upstairs said the air switch is a kind of circuit breaker. The switch is a switch that can turn on and off the load current; the disconnector is an electrical device that isolates the power supply and can not turn on and off the current (except for the voltage)

Q:What is the choice of low voltage electrical circuit breaker?

If a thermal circuit breaker is installed in an environment separate from the protected equipment, the effect of the changing ambient temperature can be corrected by a compensating hot bimetallic sheet.

Q:How is the circuit breaker connected to the circuit system diagram?

Circuit breaker: with over-current, short-circuit automatic trip function, with degaussing arc extinguishing device, can be used to connect, cut off the high current;
