Q:Circuit breaker generally choose what ah?

To this end, set the value of RCD, that is, its current I △ n movement, just to escape the normal amount of leakage current value, the value of milliamperes,

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,

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

can not turn on the current, you can disconnect the short-circuit current below the current (by fuse).

Q:Which is the circuit switch, that is the circuit breaker

so the frame circuit breaker and molded case circuit breaker applications are different occasions, the framework used in the higher into the line, molded case applied to the lower level of the framework.

Q:Short trip also tripped, overload also trip it?

The first no overload and short circuit protection only leakage protector, also known as RCD leakage switch

Q:What type of switch circuit breaker has undervoltage protection

Circuit breakers with overvoltage and undervoltage protection:

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;

Q:Is the isolator and circuit breaker able to switch to each other?

when the equipment or line is overhauled to ensure safety. In addition, you can also use the disconnector to change the running wiring.

Q:Circuit breaker auxiliary contact is what?

to prevent short-circuit, to ensure that the arc up to ensure that contact Reliable breaking of the system. The frame circuit breaker adopts the modular structure,

Q:How long does the circuit breaker last?

the introduction of intelligent circuit breaker long delay trip is based on the formula to simulate the mechanical circuit breaker trip curve, each company calculation method is different, and is the company's core secrets.
