Product details

The Siemens SENTRON 5SV4314-0LA is a 2-pole residual current circuit breaker (RCCB) rated 40 A with 30 mA sensitivity, Type AC, for 230 V AC at 50 Hz. It includes thermal overload protection, so it serves as a combined RCD/MCB in a single 2-module-width (36 mm) package that snaps onto DIN rail (REG).

The 40 A rated current, combined with thermal overload protection, means this unit can protect a branch circuit up to 40 A while also providing earth-leakage detection — no separate MCB needed upstream for the overload function.

Panel integration

Mounts on DIN rail (REG) in any position — no orientation restrictions. Grid spacing is 60 mm, standard for European distribution boards.

Frequently asked questions

Where can I buy 5SV4314-0LA and get a price?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm price and lead time.

Will 5SV4314-0LA drop into a panel specified for 5SL4363-7 without rewiring?

No. 5SL4363-7 is a 3-pole miniature circuit breaker (MCB) with a 54 mm width, while 5SV4314-0LA is a 2-pole RCCB at 36 mm wide. The footprint, function, and wiring differ — the RCCB requires both line and neutral connections, and the MCB does not provide earth-leakage protection. They are not drop-in interchangeable.

What compliance documentation does Siemens provide for 5SV4314-0LA?

The part is designed to IEC 61008-1 (RCCB standard) and carries a 10 kA SCCR per that standard. It is silicon-free. For specific declarations (RoHS, REACH, UL), refer to the manufacturer's documentation available on request.
