Nader Circuit Breaker

Circuit breaker is a very important electrical appliance in low-voltage power distribution network and electric drive system. It integrates control and multiple protection functions. In addition to completing the contact and breaking the circuit, it can also short-circuit the circuit or electrical eq...

The general selection principle of automatic air switch is: (1) Determine the type and protection form of the circuit breaker according to the protection requirements of the line-determine the choice of frame type, device type or current limiting type. (2) The rated voltage of the automatic air switc...

When the line is short-circuited or severely overloaded, the short-circuit current exceeds the instantaneous tripping setting current value, and the electromagnetic tripping device generates enough suction force to attract the armature and hit the lever, so that the hook rotates upwards around the sh...

Circuit breakers, also known as automatic switches, air switches, etc., are common circuit protectors in homes and projects. When the working current exceeds the rated current, short circuit, loss of voltage, etc., the circuit is automatically cut off to achieve protection, except for the protection ...

At present, many power companies, substations, and power distribution network industries in China have begun to use vacuum circuit breakers. This is mainly because the insulator and arc extinguishing medium of the circuit breaker are all vacuum, which has excellent insulation and arc extinguishing ef...
