Q:Selection of Circuit Breakers in Low Voltage Circuits

The thermal circuit breaker uses a bimetallic plate in series with the circuit. The heat generated by the current during the overload causes the bimetal to deform, causing the circuit breaker to trip

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:Is this an air switch or a leak protector?

The first is not overloaded. Short circuit protection. Only leakage protection RCD. Also known as leakage switch.

Q:Switch switch, disconnector, circuit breaker difference? What are the possible functions of each?

in the maintenance as a clear point, and can not carry sub-gate, or will pull the arc ACCIDENT.

Q:Is the circuit breaker in the circuit necessary?

when the current is slightly larger, will only cut off the other two phase to produce too much electric current Arched open

Q:Is it possible to switch the lamp directly with a circuit breaker?

Circuit breaker according to its use is divided into high-voltage circuit breakers and low-voltage circuit breakers, high and low voltage line is more vague, generally more than 3kV called high-voltage electrical appliances.

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

If you have a circuit in the circuit where the split switch is installed, you can use the following methods to quickly handle:

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 type of switch circuit breaker has undervoltage protection

Circuit breakers with overvoltage and undervoltage protection:

Q:The difference between the leakage switch of the air switch circuit breaker

Mainly used for short circuit and overload protection. General 1P1P plus N or 2P. 3P or 4P, etc.
