It provides CLASS 10 thermal overload protection and includes phase failure detection, so it catches a lost phase before the motor overheats. Zero clearance at the sides and rear (0 mm) means you can pack it tight against adjacent devices without derating for airflow. Continuous current 32 A sets the motor FLA it can protect. The 15 kW rating at 400 V AC-3 matches a standard 15 kW induction motor on a 400 V line. Breaking capacity steps down with voltage: 100 kA at 240 V, 50 kA at 400 V, 10 kA at 500 V, 4 kA at 690 V — so at 400 V it handles high-fault utility feeds; at 690 V it still clears a 4 kA fault, which covers most industrial transformer secondaries. Power dissipation runs 19 W total in hot operating state, 6.3 W per pole. That matters for enclosure heat rise — in a dense panel with several breakers, the cumulative heat can push the ambient above the rated -20 to +60 °C operating range. The surge voltage withstand is 6 kV, which covers most industrial impulse environments. Dimensions are 55 mm wide, 140 mm high, 149 mm deep, so it occupies a standard 3-module width on the rail. The screw terminals accept solid conductors up to 2x 16 mm² and stranded up to 2x 25 mm² or a single 35 mm² — enough for the 32 A feed. Auxiliary switch extension is supported (product extension auxiliary switch: Yes), so you can add a signal contact for remote status or PLC feedback without replacing the breaker. The screw terminals for the auxiliary circuit are separate from the main current circuit terminals.","metaTitle":"Siemens 3RV1031-4EA10-ZW96 SIRIUS Motor Protective Circuit B","metaDescription":"Siemens 3RV1031-4EA10-ZW96 SIRIUS motor-protective circuit breaker, 32 A continuous, 15 kW at 400 V, CLASS 10 trip, phase failure detection, 50 kA breaking capacity at 400 V.
