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.","metaTitle":"Siemens 3RV2341-4KC10 SIRIUS Circuit Breaker, 30 kA at 400 V","metaDescription":"Siemens SIRIUS 3RV2341-4KC10 circuit breaker for starter combinations.
