Product details

Motor protection circuit breaker with integrated overload relay

Rated at 65 A (at 480 V) and 62 A (at 600 V), this breaker handles motor loads up to 18.5 kW at 230 V or 25 hp at 220/230 V. The breaking capacity reaches 30 kA at 400 V, 5 kA at 500 V, and 2 kA at 690 V — sufficient for most industrial distribution panels with transformer-fed fault currents. Any mounting position is allowed. Screw-type terminals accept 2× (1…35 mm²) or 1× (1…50 mm²) solid or stranded copper, with M6 main contact bolts.

Dimensions: 75 mm wide, 140 mm high, 149 mm deep — fits standard 8-module-wide DIN-rail spacing. Switching frequency limited to 15 operations per hour at AC-3 and AC-3e duty — adequate for motor starting cycles in conveyor, pump, and fan applications. For higher cycling (frequent jogging or inching), consider a contactor-based solution with a separate motor protection relay.

Frequently asked questions

What is the breaking capacity of the 3RV2131-4JA10 at 400 V?

The 3RV2131-4JA10 has a breaking capacity of 30 kA at 400 V AC, 5 kA at 500 V, and 2 kA at 690 V. At 240 V it reaches 100 kA.

Does the 3RV2131-4JA10 include phase failure protection?

Yes, phase failure detection is built into the 3RV2131-4JA10. It will trip the circuit if a phase is lost, preventing single-phasing damage to the motor.

What wire sizes fit the 3RV2131-4JA10 terminals?

The screw-type main circuit terminals accept 2× (1…35 mm²) or 1× (1…50 mm²) solid or stranded copper conductors. Main contact bolts are M6.

How do I get current pricing and availability for the 3RV2131-4JA10?

Submit an RFQ through this listing. Pricing and availability are confirmed at quote time through independent distribution channels — no stock count or price is published here.

What is the closest functional second-source for the 3RV2131-4JA10?

The 3RV2023-4DA10 is a similar SIRIUS motor protection circuit breaker but in a smaller frame size with lower ratings. It will not drop into a panel wired for the 3RV2131-4JA10 without rewiring — the terminal spacing, width, and clearance distances differ. Verify your load current and fault current requirements before substituting.
