NSX NS DPX ABB TMAX 3VL CM1 DW45  MCCB provide the function of isolation switching and earth leakageprotection of electrical circuits.
RCBO circuit breaker

Residual current circuit breaker, rccb, earth leakage circuit breaker, elcb
Application
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.
Construction features
- 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.
