Product details

What this breaker does on your line

Trip Class 20 means it lets a motor pull starting current for up to 20 seconds before tripping, which covers most standard induction motors on pumps, fans, and compressors. At 55 mm wide it takes one standard module slot — leaves room for the contactor and overload block next to it.

Mounting position any — horizontal, vertical, upside-down, doesn't care. Depth 149 mm, width 55 mm, height 140 mm. Main contact terminals take M6 screws; solid or stranded wire up to 2x 2.5 mm².

Frequently asked questions

How do I get current pricing and availability for 3RV2031-4DB15-ZX95?

Submit an RFQ through the storefront. Availability and current pricing are confirmed at quote time through independent distribution channels.

What is 3RV2031-4DB15-ZX95's interrupting rating at 400 V?

30 kA at 400 V rated value — that's the short-circuit breaking capacity you need for your SCCR calculation.

Will 3RV2031-4DB15-ZX95 drop into a panel that was specified around 3RV2021-4NA25 without rewiring?

Both are SIRIUS motor protection breakers on the same 55 mm DIN-rail footprint, but the 3RV2031 carries higher interrupting capacity (30 kA vs lower values on the 3RV2021). Check your fault current study — if the panel requires 30 kA, the 3RV2031 is the correct fit; if the original spec was lower, the 3RV2031 still works but costs more. Wiring terminals and clearance dimensions are the same.

What compliance documentation does this brand provide for 3RV2031-4DB15-ZX95?

As a Siemens SIRIUS product, it carries CE marking and is designed to meet IEC/EN 60947 standards for motor protection circuit breakers. RoHS and REACH declarations are available through Siemens' documentation portal.
