The Siemens 5SV4346-0MB is a 4-pole residual current operated circuit breaker (RCCB) from the SENTRON series, rated 63 A with 30 mA residual sensitivity for Type AC waveforms at 400 V AC. The 30 mA trip threshold covers personnel protection (indirect contact) per IEC 61008-1; the 63 A continuous rating matches the main incomer or subfeed on a three-phase panel.
Depth is 70 mm, matching the standard SENTRON RCCB envelope.
This part is sourced to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for the latest commercial terms.
It is a 4-pole Type AC residual current circuit breaker (RCCB) for 400 V three-phase circuits, rated 63 A with 30 mA residual sensitivity. It provides earth leakage protection for personnel and equipment in distribution boards, typically as an incoming or subfeed device.
The 5SV4346-0MB is designed according to IEC 61008-1 for RCCBs. It is rated for overvoltage category III and carries a silicon-free construction. The product is part of the SENTRON series with standard Siemens documentation including the datasheet and declaration of conformity.
