Product details

The Siemens 3RV1031-4EA10-ZW98 is a SIRIUS motor protection circuit breaker rated for 32 A continuous current and 15 kW at 400 V AC-3 duty.

Breaking capacity is 100 kA at 240 V AC, 50 kA at 400 V AC, 10 kA at 500 V AC, and 4 kA at 690 V AC. That simplifies panel coordination: you can feed it from a standard 50 kA-rated bus without adding a fuse block.

The main circuit accepts 2x (0.75…16 mm²) solid or 2x (0.75…25 mm²) stranded, plus a single 0.75…35 mm² stranded — enough for the 32 A feed without doubling up. Auxiliary switch extension is supported, so you can add a remote trip-indication contact without a separate interposing relay.

Frequently asked questions

Can I add an auxiliary switch to this breaker?

Yes, the product extension auxiliary switch is supported, so you can add remote trip indication.

What compliance documentation does this part carry?

RoHS compliance dated 07/01/2006; IP20 front protection.
