The Siemens 5SV3744-6 is a 4-pole residual current operated circuit breaker (RCCB) from the SENTRON family, rated 40 A with a 500 mA residual operating current at 400 V AC.
Depth is 70 mm, height 90 mm. Mounts in any position.
The short-circuit current rating is 10 kA, which governs the maximum fault current the device can safely interrupt.
The 5SV3744-6 is sourced and quoted to order against an RFQ through independent distribution channels; current pricing and availability are confirmed at quote time.
The 5SL4363-7 is a 3-pole miniature circuit breaker (MCB), not an RCCB. The 5SV3744-6 is a 4-pole residual current device. They serve different protection functions — one for overcurrent, one for earth leakage. Panel space differs: the 5SV3744-6 occupies 4 MW (72 mm) vs 3 MW (54 mm) for the 5SL4363-7.
