At 230 V it's rated for 22 kW motor loads, and it covers the full voltage range from 20 to 690 V, so it adapts to whatever line voltage the plant throws at it. ## Mounting and wiring — panel fit Any orientation. Screw terminals accept up to 2x 35 mm² or 1x 50 mm². Clearances: 50 mm above and below, 10 mm sides, zero forward or backward. Depth is 149 mm. ## Breaking capacity by voltage — the selectivity story The breaking capacity isn't a single number — it varies with system voltage. At 240 V it's rated for 100 kA, at 400 V it drops to 30 kA, at 500 V it's 5 kA, and at 690 V it holds at 2 kA. The 2 kA at 690 V is enough for most 690 V motor circuits, but verify your available fault current if you're close to the transformer.","metaTitle":"Siemens 3RV2331-4RC10 SIRIUS Circuit Breaker, 30 kA at 400 V","metaDescription":"Siemens SIRIUS 3RV2331-4RC10 circuit breaker for starter combinations. 30 kA breaking capacity at 400 V, 22 kW at 230 V.
