Rated 40 A with 30 mA sensitivity, Type AC, it provides instantaneous earth-fault protection for 2-pole circuits on 230–240 V AC 50/60 Hz networks.
The 30 mA sensitivity is the residual current that triggers the instantaneous trip; this is the standard threshold for personal protection against electric shock in residential and commercial final circuits.
Panel Integration & Wiring
IP20 on the body, IP40 inside a modular enclosure.
Rated insulation voltage 500 V AC; rated impulse withstand voltage 6 kV. The 8/20 µs impulse withstand of 250 A per IEC 61009-1 ensures the device does not nuisance-trip on surge currents.
