Uninterrupted energy, maximum safety and intelligent residual current management with Sigma SCRC03 Recloser for Residual Current Circuit Breaker!

Sigma SCRC03 is an accessory that automatically re-energizes the circuit breaker to ensure system continuity in the case of a residual current circuit breaker failure.

Sudden pulses, transient voltage fluctuations and harmonic components in the power grid can be misinterpreted by the residual current circuit breaker as system leakage. When such transient cases cease, there is no more leakage current in the system.

Sigma SCRC03 Recloser for Residual Current Circuit Breaker waits for 10 seconds after the initial trip and then automatically recloses the circuit breaker when a transient case occurs that disables the residual current circuit breaker. If the leakage current continues, the residual current circuit breaker will open the circuit again and Sigma SCRC03 will reactivate, this time waiting for 60 seconds. If the leakage current is still at presence, the third and final reset will occur at 300. second. If the residual current circuit breaker opens the circuit at this point, the fault in the system must be intervened.
