Isolates a three-phase line from earth faults at a 300 mA threshold.
This four-pole residual current circuit breaker protects three-phase circuits up to 40 A and opens its contacts at a 300 mA leakage. It runs on a 400/415 V supply at 50 Hz and takes up 4 modules of width in the board.
Earth leakage protectionMonitors earth leakage and opens the circuit at the 300 mA threshold.
Load currentCarries up to 40 A across four poles.
Sensitivity typeWorks as an AC type against alternating residual currents.
Space in the boardA 4 module wide modular housing fits the distribution board.
Supply compatibilityOperates at a 400/415 V supply and a 50 Hz 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.
