Product details

The 3RV2341-4MC10 occupies 70 mm width, 165 mm height, and 176 mm depth on the DIN rail. The main circuit uses screw-type terminals accepting 2x (2.5...16 mm²) solid or 2x (2.5...50 mm²) / 1x (10...70 mm²) stranded. Wire the line and load through these; the auxiliary terminals are separate. Motor horsepower ratings span 7.5 hp at 110/120 V up to 100 hp at 575/600 V, covering a wide range of induction motor sizes.

Environmental and mounting notes

The part has no ground fault or phase failure detection — it is a straight thermal-magnetic or electronic overload device for motor protection, not a multifunction monitor. Rated switching frequency for AC-3 and AC-3e duty is 15 operations per hour maximum, so it is intended for intermittent motor starting, not continuous switching.

Frequently asked questions

How do I get current pricing and availability for 3RV2341-4MC10?

This part is sourced to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.

What is 3RV2341-4MC10's listed depth?

The depth is 176 mm.

What wire sizes does the 3RV2341-4MC10 accept?

Solid wire: 2x (2.5...16 mm²). Stranded: 2x (2.5...50 mm²) or 1x (10...70 mm²).

Will 3RV2341-4MC10 drop into a panel specified around 3RV2021-4NA25 without rewiring?

Both are SIRIUS circuit breakers for starter combinations on 35 mm DIN rail, but the 3RV2341-4MC10 is a physically larger frame (70 mm wide vs the 3RV2021 series typically 45 mm). Check the panel depth and clearance — the 3RV2341-4MC10 requires 150 mm above and below, and its 176 mm depth may exceed the earlier frame's footprint. Terminals are screw-type on both, but wire range differs; verify the lug sizes against your existing wiring.
