Nader Circuit Breaker

As a low-voltage circuit-breaker used in the selection have the following main aspects: First, according to the workplace to meet the requirements of its type and technical parameters; secondly to determine a good breaker in the preliminary varieties and specifications, they still think about it and ...

Air Circuit Breaker commonly known as automatic air switch, the distributor is automatically breaking the circuit when overload, short circuit or undervoltage circuit occurred. It is one of the important low-voltage AC and DC power distribution system protection appliances. Capacity of the air circui...

Phase four-wire (0.4 / 0.23KV) power system selection principle of four-pole switch: switch between a normal power supply and a backup generator application four-pole switch. Residual current protection with dual power switch 2 should quadrupole switch. Grounding power switch in the same system, two ...

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...
