Opens its contacts at a 300 mA leakage on a three-phase line.
This four-pole residual current circuit breaker protects three-phase circuits up to 63 A and opens its contacts at a 300 mA leakage. It takes up 4 modules of width in the board and runs at a 50/60 Hz supply frequency.
Earth leakage protectionMonitors earth leakage and opens the circuit at the 300 mA threshold.
Load currentCarries up to 63 A across four poles.
Sensitivity typeDelivers reinforced immunity against impulse currents as an A[IR] type.
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 3000 A surge current with an 8/20 µs waveform.
