Residual current circuit breakers (RCCB) provide the function of electric circuit control and can protect people against indirect contacts and additional protection against direct contacts. It can also protect installations against fire hazard due to insulation faults. Residual current circuit breakers (RCCB)are used in housing, tertiary sector and industry.Key products series include:NL1, NL210, NXL series,etc.  

The main benefits include that of the limit short circuit current is up to 10kA;The shell and other plastic parts are made of high flame retardant, high temperature resistant and impact resistant plastic;
Installation guide rail and size modularization;   
The dynamic test device makes the button more flexible and reliable;
The Rated impulse withstand voltage(1.2/50) Uimp is up to 6kV.
