Short-circuit breaking capacity at 400 V is 30 kA — sufficient for most industrial distribution panels with typical transformer sizes. At 690 V it still interrupts 2 kA, covering drive input protection in 690 V line applications. Any mounting position allowed. Dimensions: 55 mm wide, 140 mm tall, 149 mm deep — fits standard 55 mm modular device slot on the rail. Side clearance of 10 mm and vertical clearance of 50 mm (upwards and downwards) for heat dissipation and arc venting. Main contact terminals accept M6 bolts; solid or stranded conductors up to 2x 2.5 mm² per clamp. Current production lifecycle stage per Siemens.","metaTitle":"Siemens 3RV2031-4UA15 SIRIUS Motor Protection Circuit Breake","metaDescription":"Siemens 3RV2031-4UA15 SIRIUS motor protection circuit breaker, Class 10, 30 kA at 400 V, phase failure detection, DIN rail mount.
