Nader Circuit Breaker

High-voltage circuit breakers have arc extinguishing capabilities and are the main equipment for circuit breakers. Normally, according to the operation requirements of the grid, some electrical equipment or lines are put into or out of operation. When the electrical equipment or line fails, the prote...

1P, 1P+N and 2P circuit breakers are all used for the control and protection of single-phase power circuits. So what is the difference between them and the application effect? 1. Definition of 1P, 1P+N and 2P circuit breakers A. 1P circuit breaker single-pole circuit breaker, with thermal tripping fu...

There are 3 wires from the electric meter to the home, red and blue flowers, you can use an air switch with leakage protection as the master control switch (A0), and there are three ordinary air switches to control the lights (A1), Air conditioner (A2), socket (A3). Viewed from the front, there are 2...

For miniature circuit breakers, 1P+N, 1P, 2P are generally used as on-off control of single-phase electrical appliances, but the effects are different. 1P-single pole circuit breaker, with thermal and magnetic trip function, only control live wire (phase wire), modulus 18mm; 1P+N-single pole +N circu...
