NBSe BF62 Series Residual Current Circuit Breaker, elcb
A residual-current device (RCD), or residual-current circuit breaker (RCCB), is a device that quickly breaks an electrical circuit to prevent serious harm from an ongoing electric shock.
· Line voltage independent RCCB for fault or additional protection with additional digital features
· System Monitoring: Preventive information / warning before the RCD trips in case of leakage currents: Integrated auxiliary contact(s), Local Indication
· New level of accuracy - Reduced unwanted tripping
· Local status indication of residual current through 3 LEDs
· No monthly test required
· Comprehensive range of accessories
· Real contact position indicator
· Fault current tripping indicator
· Automatic re-setting possible
· Transparent designation plate
