Product details

The Siemens SENTRON 5SM2625-0 is a 2-pole residual current device (RCD) of type AC, rated at 63 A and 300 mA sensitivity, for 230 V AC 50 Hz systems. This is the companion RCD unit for the 5SY miniature circuit breaker series, intended for snap-on integration into distribution boards where it provides earth leakage protection.

Rated 63 A at 230 V AC, 300 mA sensitivity, type AC. 2-pole switches phase and neutral. The 2 MW modular width (each MW = 18 mm) means the unit occupies 36 mm of DIN-rail space, matching the footprint of a standard 2-pole MCB.

Deployment context

Snap-on DIN rail mount, any position. IP20 when installed in distribution board with connected conductors. Ambient -5 °C to 45 °C, storage -40 °C to 75 °C.
