Product details

Motor protection circuit breaker for 3-phase loads

It combines a thermal overload relay and a magnetic short-circuit release in one DIN-rail-mounted package.

Rated breaking capacity hits 100 kA at 240 V, 50 kA at 400 V, and 4 kA at 690 V. That 50 kA at 400 V covers most industrial service-entrance fault levels — you can place this breaker close to the transformer without worrying about upstream coordination.

Width is 55 mm — fits a standard 3-module footprint. Any mounting position is acceptable, so you can lay it sideways in a shallow gland plate if needed.

Frequently asked questions

What are the key ratings for 3RV2032-4PA15?

Trip Class 10, breaking capacity 100 kA at 240 V and 50 kA at 400 V, phase failure detection included. Width 55 mm, depth 149 mm, height 140 mm. Mounts on 35 mm DIN rail.

Will 3RV2032-4PA15 drop into a panel specified around 3RV2021-4NA25?

Both are SIRIUS motor protection breakers on the same DIN rail footprint, but the 3RV2032-4PA15 is physically larger (55 mm wide vs the 3RV2021 frame's 45 mm). Verify panel space and busbar spacing before swapping — the 3RV2032 series carries higher breaking capacities and may need more clearance.

Where can I buy 3RV2032-4PA15 and how is it quoted?

This part is sourced to order through independent distribution. Submit an RFQ for current pricing and availability — quotes are confirmed at the time of request.
