Residual Current Circuit Breakers (RCCB)

Residual-current circuit breakers in 1P+N, 2-pole and 4-pole configurations, with selected 30 mA and 100 mA sensitivities and AC or Type A characteristics. An RCCB detects earth-leakage current but does not provide overload protection, so it must be coordinated with suitable overcurrent protection. Pole count, current rating, sensitivity and RCCB type must be selected by a qualified electrician for the application.
