Earth Leakage Circuit Breaker(ELCB), Residual Current Device(RCD), Residual Current Circuit Breaker(RCCB)
Brand Name: Meba
Model Number: NFIN
Type: Residual Current Circuit Breaker or Residual Current Device
Poles Number: 2P
1. NFIN Residual Current Circuit Breaker provide the function of isolation switching and earth leakage protection of electrical circuits.
2. 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.
– 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.Merits：
Good quality , high breaking capability, updated structure,quick trip and guide installation, competitive price,excellent and safe performance,beautiful and compact appearance, etc .
