Isolates a three-phase line from earth faults with Type A sensitivity.
This four-pole residual current circuit breaker protects three-phase circuits up to 40 A and opens its contacts at a 30 mA leakage. It meets the IEC/EN 61008-1 standard and runs at a 50/60 Hz supply frequency.
Earth leakage protectionMonitors earth leakage and opens the circuit at the 30 mA threshold.
Load currentCarries up to 40 A across four poles.
Sensitivity typeWorks with Type A residual current detection.
Space in the boardA 4 module wide modular housing fits the distribution board.
Supply compatibilityOperates at a 50/60 Hz supply frequency.
Insulation and impulse withstandWithstands a 500 V insulation voltage, a 4 kV rated impulse voltage and a 250 A surge current with an 8/20 µs waveform.
