NFIN Residual Current Circuit Breaker provide the function of isolation switching and earth leakage protection of electrical circuits.And also provide the indirect protection of the operator's body against the dangerous effects of electric current and provide the protection of the fire caused by the electrical circuit fault.
Our products have the guarantee period of 36 calendar months,that is a high quality and reliability;
Our products have an excellent ratio between price and quality ,you can possess them by competitive price and high quality;
The fast and flexible production form aim at the customer require;
The deliveries exactly in accordance with customer orders
The fast transportation.
Adopt electromagnetic style release , can play a leak electricity and electric shock protecting role while breaking in zero Line.
Measuring component and buckling component of products is located between enter line end and entrance line end ;
Movement characteristic of products can not be changed with outside mechanical tool ;
The operating organization has the free function to take off and buckle;
Operate part can not be taken down from the shell outer of products , the shell can not influence the operating organization to work , the accessory group which replace the feelers pressure, should guarantee the feelers pressure does not change while running.
