The breaking capacity hits 100 kA at 400 V AC, dropping to 10 kA at 500 V and 6 kA at 690 V, which covers most industrial distribution panels. Zero clearance at the sides and rear, so it packs tight in a panel. Screw-type box terminals on the main circuit accept 2x (2.5–16 mm²) solid or 2x (10–50 mm²) stranded; auxiliary and control circuits use separate screw terminals. IP20 on the front, finger-safe touch protection per the standard.","metaTitle":"Siemens 3RV1342-4KC10 SIRIUS Circuit Breaker, 75 A, 37 kW at","metaDescription":"Siemens 3RV1342-4KC10 SIRIUS circuit breaker for starter combinations. 75 A continuous, 37 kW at 400 V, 100 kA SCCR at 400 V.
