The Siemens SENTRON 5SM9323-0 is a residual current (RC) unit designed to snap onto a 5SL4 miniature circuit breaker, creating a combined RCBO assembly. It's a 2-pole, type AC device rated at 40 A with 30 mA sensitivity, operating at 400 V AC, 50 Hz.
The supply connects to the top, above the miniature circuit breaker. Installation depth is 70 mm. IP20 rating applies once the distribution board cover is fitted with conductors connected — so it's panel-internal, not for wet or outdoor locations.
2-pole, type AC residual current unit, 40 A rated current, 30 mA sensitivity, 400 V AC supply, 50 Hz, 6 kA breaking capacity per EN 60898 and IEC 61008-1.
The 5SM9323-0 is a different device class — it's an RC unit for the 5SL4 MCB, not a standalone miniature circuit breaker like the 5SL6550-7BB. Both share the same 36 mm width and 70 mm installation depth, so the DIN-rail footprint matches, but the 5SM9323-0 requires a 5SL4 breaker to function as an RCBO assembly.
