Design Of The ProductFor starter combinations

Product details

The Siemens SIRIUS 3RV2341-4KC10 is a circuit breaker designed for starter combinations — the kind you drop into a motor control center to protect the feeder and the contactor downstream. The interrupting ratings tell the real story here: 30 kA at 400 V and 65 kA at 400 V AC. At 240 V AC it's rated 100 kA, so it also covers secondary-side faults in step-down transformers. Terminal capacity is generous: screw-type terminals accept 2x (2.5 to 16 mm²) solid or stranded on the control side, and 1x (10 to 70 mm²) or 2x (2.5 to 50 mm²) on the main circuit. That covers most motor feeder cables up to around 75 A at 600 V (the rated current at 600 V is 75 A).

Dimensions and spacing

The breaker occupies 70 mm width, 165 mm height, and 176 mm depth — a compact footprint for a device that can interrupt 65 kA. That means you can butt it against the backplane or a busbar without extra air gap.

Frequently asked questions

What is the interrupting rating of 3RV2341-4KC10 at 400 V?

At 400 V the breaker is rated 30 kA; at 400 V AC it is rated 65 kA. The higher AC figure applies when the supply is AC, not DC.

What mounting does 3RV2341-4KC10 require?

It mounts via screw and snap-on onto 35 mm DIN rail per DIN EN 60715, in any orientation. Clearance needed: 150 mm above and below, 30 mm to the sides.

Where can I buy 3RV2341-4KC10?

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