Nader Circuit Breaker

1, the working principle and structure of low voltage circuit breaker switches, commonly known as air, low-voltage electrical switch with a main power grid may be switched on or breaking normal load current, motor current, overload current, short-circuit current is not applied to frequent operation l...

Undervoltage release is in its terminal voltage drops below a predetermined range, there is a delay circuit breaker or disconnecting a delay-free release when the supply voltage drops (or even slow down) to the rated work within the range of 70 to 35% voltage, under-voltage release should operate und...

The working principle of low voltage circuit breaker low voltage circuit breaker: low voltage circuit breaker having a plurality of protection functions (overload, short circuit, under voltage protection, etc.), the operation is adjustable, high breaking capacity, easy operation, safety, etc., so tha...

Control of the low voltage circuit breaker cabinet, which is to control the closing and opening. Place divided by control local control and centralized control of two. In the vicinity of the circuit breaker (electromagnet or motor) to complete the closing, opening task is operated locally operating a...

Causes and treatment can result in high voltage circuit breaker closing follows: (1) gear stuck or mounting position, properly adjusted. Respond transmission mechanism for maintenance, proper installation and adjustment of the transmission mechanism. (2) auxiliary contact switch contact failure. Deal...
