Depth of 149 mm means it protrudes less than a standard contactor block — fits in shallow enclosures where a 200 mm deep breaker would hit the gland plate. Clearance requirements: 50 mm upwards, 50 mm downwards, 10 mm to the side for arc-chamber venting. Terminals accept 2x (0.5...1.5 mm²) or 2x (0.75...2.5 mm²) solid or stranded — covers control wiring up to 14 AWG. Main contacts use M6 bolts, standard for motor-circuit breakers in this frame size. No ground-fault detection built in — that is a separate module if your installation requires it.","metaTitle":"Siemens 3RV2031-4WB15-ZX95 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens SIRIUS 3RV2031-4WB15-ZX95 motor protection circuit breaker, CLASS 20, 160 kA breaking capacity at 400 V.
