The 30 mA trip threshold is standard for personnel protection in most IEC installations — it's the go-to for socket-outlet circuits and general wet-area protection. The 63 A continuous rating matches a typical main switch or feeder for a sub-distribution board. Short-circuit withstand is 10 kA per IEC 61008-1, with an additional conditional rating of 0.8 kA for the residual current function. That 10 kA figure governs the upstream breaker coordination: the RCCB sits behind a 10 kA-rated MCB or fuse. That's not negligible in a crowded enclosure; factor it into the thermal budget, especially if the RCCB is grouped with other heat-generating devices. ## Mounting and fit Depth is 70 mm, so it sits flush with most 70 mm-deep distribution boards. The IP20 rating applies only when the distribution board is installed and conductors are connected; that's standard for enclosed panels. Silicon-free construction matters for applications where silicone outgassing can contaminate contacts or optical surfaces — automotive paint shops or certain medical environments. Supplementary devices (like auxiliary switches or shunt trips) can be added on the right side.","metaTitle":"Siemens 5SV3346-6KL SENTRON RCCB, 4P, 63 A, 30 mA, 400 V AC","metaDescription":"Siemens 5SV3346-6KL SENTRON RCCB, 4-pole type A, 63 A, 30 mA, 400 V AC, N left, 10 kA SCCR.
