Siemens 5SM26476 RC Unit for 5SP4 Miniature Circuit Breaker — 4-Pole, Type A, in 100 A, 300 mA, 400 V AC

The Siemens 5SM26476 is a SENTRON 5SM2 RC unit — a residual current (RCD) block that clips directly onto a Siemens 5SP4 miniature circuit breaker. The assembled pair works as a combined residual-current and overcurrent protective device to DIN EN 61009-1, so one device gives both protection against electric shock and earth-fault fire and the line protection of the MCB behind it. This version is Type A: it detects sinusoidal AC residual currents and pulsating DC residual currents, which is the type required for circuits feeding electronic loads. It is 4-pole, rated 100 A at 400 V AC, with a rated residual current of 300 mA. It suits 5SP4 miniature circuit breakers rated 80/100 A. Device depth is 70 mm. Supplied by cBallast on quote-to-invoice terms; lead time and freight are quoted per RFQ against the destination Incoterm.
