Q:Where will the circuit breaker auxiliary contacts be used? ,

generally do not consider maintenance, suitable for branch protection switch, over current release There are two kinds of electromagnetic and electronic

Q:How to protect the leakage protector leakage protection?

Capture leakage, electric shock and other ground fault current. Trip and strokes according to its breaking reaction time cut off the power

Q:Selection of Circuit Breakers in Low Voltage Circuits

that is, after the trip can be reset. They can also be used as power-on / off switches for protected equipment.

Q:Load switch, vacuum switch and circuit breaker

Load switch: can safely cut off the load current, can not cut off the short circuit current

Q:s the MCB switch a circuit breaker or a component on the circuit breaker?

The determination of the total switch circuit breaker in the household distribution box is determined by the sum of the rated current of all the branch circuit breakers in the distribution box

Q:The difference between air switch and circuit breaker

Such as short circuit protection, over current protection, exclusion control, undervoltage protection. The first two kinds of protection for the basic configuration of the air circuit breaker, the latter two for the optional function

Q:Circuit system diagram how the circuit breaker said

so as to avoid serious equipment and personal accidents. Only the voltage transformer, arrester, the excitation current does not exceed 2A no-load transformer

Q:Double control switch circuit diagram

In the bedroom you can also have a switch to control the living room lights. The same in the factory in the face of a motor control is very common two things

Q:What type of switch circuit breaker has undervoltage protection

For example: Model DZ10-100 / 330 circuit breaker with over voltage, undervoltage protection function, from its model in the symbol / behind the second 3

Q:What is the specific function of the auxiliary switch on the circuit breaker switch?

By the secondary equipment connected to each other, constitute a primary equipment for monitoring,
