Product details

It trips in CLASS 10 (under 10 seconds at locked rotor), so it clears a stalled motor fast enough to keep the windings from cooking — that's the main reason you'd pick this over a slower thermal breaker.

The 3RV1041-4MA15 delivers 100 kA breaking capacity at 240 V AC, 50 kA at 400 V AC, 8 kA at 500 V AC, and 5 kA at 690 V AC.

Installation notes

Zero clearance required at the sides or rear — the 70 mm width and 165 mm height fit a standard DIN-rail footprint. Any mounting position works; no derating for orientation. Shock rated to 25g for 11 ms, so it holds up in mobile or vibrating equipment.

Frequently asked questions

What are the key ratings of 3RV1041-4MA15?

100 A continuous rated current, CLASS 10 trip, 45 kW at 400 V AC-3, 50 kA breaking capacity at 400 V AC. Phase failure detection is included; ground fault detection is not.

Where can I buy 3RV1041-4MA15?

It's quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — send an inquiry.

Will 3RV1041-4MA15 drop into a panel designed for 3RV2021-4NA25?

Both are SIRIUS motor protection breakers with similar DIN-rail mounting and screw terminals, but the 3RV2021-4NA25 is a different generation with potentially different dimensions and breaking capacities. Verify the mounting footprint and available fault current before swapping — the 3RV1041-4MA15 has a 100 A rating and 50 kA at 400 V, while the 3RV2021 series may differ.
