CB7RL-63 series electromagnetic residual current circuit breaker is designed for AC distribution networks with a rated voltage of 230V or 400V, 50/60Hz, and a rated current up to 63A. It provides protection against indirect contact for personnel and helps prevent fire risks caused by insulation faults in circuits or equipment that lead to ground fault currents.
Detectable wave form
Tripping is ensured for slowly increasing sinusoidal AC residual currents.
Tripping is ensured for sinusoidal AC residual currents and for pulsed DC residual currents, whether applied suddenly or increasing slowly.
Tripping sensitivity
Tripping time
Instantaneous. It ensures instantaneous tripping (without time-delay).
