No ground-fault detection on this variant — that's handled separately in the circuit if required. Any mounting position is acceptable, which simplifies panel layout. ## Short-circuit breaking capacity — what it interrupts The interrupting rating varies with line voltage: 100 kA at 240 V AC, 50 kA at 400 V AC, 10 kA at 500 V AC, and 4 kA at 690 V AC (–). ## Termination and wiring Main circuit terminals are screw-type with box terminals. Accepts stranded wire: 2x (0.75... 25 mm²) or 1x (0.75 … 35 mm²). Solid wire: 2x (0.5... 1.5 mm²) or 2x (0.75... 2.5 mm²). AWG equivalents for main contacts: 2x (18... 2) or 1x (18... 2). Auxiliary and control circuit also use screw-type terminals. RoHS compliance dated to 07/01/2006. Shock rated at 25g / 11 ms. Power dissipation in hot operating state: 29 W.","metaTitle":"Siemens 3RV1031-4HB15-ZX95 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens SIRIUS 3RV1031-4HB15-ZX95 motor protection circuit breaker. 50 A continuous, 22 kW at 400 V, Trip Class 20.
