The 5SU1353-1WM13: Rated breaking capacity is 4.5 kA per EN 60898 and 15 kA per IEC 60947-2, giving the buyer two compliance paths: the lower figure for residential distribution boards, the higher for industrial panel coordination where SCCR headroom matters. The residual-current element is Type AC — sensitive to sinusoidal AC fault currents only. That covers the majority of standard socket-outlet and lighting circuits; for pulsed or smooth DC fault currents (e.g. from VFDs or EV chargers), a Type A or Type B device would be needed.
Installation depth is 70 mm. Occupies 2 MW width. Tightening torque is 2.5 to 3 N·m with screw-type terminals. Touch protection is built in. Power dissipation is 4.4 W maximum — relevant for thermal derating in a crowded enclosure. The device is halogen-free and silicon-free, meeting clean-room or low-corrosion requirements.
