Product details

RCCB for 4-wire circuits, Type A sensitivity

The Siemens 5SM1352-6 is a 4-pole residual current circuit breaker (RCCB) from the SENTRON 5SM1 series, rated 25 A at 500 V AC with a 30 mA trip threshold and Type A fault-current detection. The 30 mA sensitivity covers personnel protection (≤ 30 mA is the IEC threshold for direct-contact shock protection).

Thermal derating and conductor sizing

Above that the current must be derated: 24 A at 50 °C, stepping down to 20 A at 70 °C. The terminal range accepts 1.5 mm² minimum to 25 mm² maximum — the 25 mm² upper limit covers most 25 A feeder conductors in copper, so no lug adapter is needed for standard panel wiring.

Mounting position is unrestricted — top or bottom feed is acceptable. The IP20 rating applies once the distribution board is closed and conductors are connected; the enclosure itself provides the environmental seal. Finger and back-of-hand touch protection is built in, meeting the shock-protection requirements for live-terminal access inside a locked panel.

Frequently asked questions

What is 5SM1352-6's listed maximum and minimum conductor size?

The terminal accepts conductors from 1.5 mm² minimum up to 25 mm² maximum. The 25 mm² upper limit covers standard 25 A feeder runs without requiring pin lugs or reducers.

What compliance documentation does Siemens provide for 5SM1352-6?

The part carries the SENTRON brand and is designed to IEC/EN 61008 standards for RCCBs. It is silicon-free and rated for overvoltage category III. Specific RoHS/REACH declarations and the CE declaration of conformity are available from Siemens documentation — the order code 5SM1352-6 is the reference for pulling those certificates.

Where can I buy 5SM1352-6 and get current pricing?

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 estimate.
