Rated at 690 V, it delivers a breaking capacity of 50 kA at 400 V AC, dropping to 10 kA at 500 V and 4 kA at 690 V. The 15 kW rating at 400 V gives a quick power-to-current cross-check: if your motor nameplate says 15 kW at 400 V, this breaker is the right thermal match for that load. The 55 mm width and 140 mm height fit the standard SIRIUS footprint — it occupies one slot in a multi-device rail assembly. Depth is 149 mm, so account for that behind the panel door — it's not a shallow device. Main circuit terminals are screw-type with box terminals, accepting solid conductors up to 2x 16 mm² and stranded up to 2x 25 mm² or a single 35 mm². Auxiliary and control circuit terminals are also screw-type. The product extension for an auxiliary switch is available — useful if you need a remote status signal back to the PLC. RoHS compliance date is July 1, 2006, which covers the EU RoHS directive. The substance prohibition date is on record, so it meets the standard environmental compliance requirements for European markets. ## Environmental limits Operates from -50 °C to +60 °C and survives storage and transport from -50 °C to +80 °C. That's a wide operating range — it handles cold storage environments or hot panel conditions near motor drives. Shock resistance is 25g for 11 ms, which is standard for industrial panel-mounted gear. That's moderate heat — factor it into your panel thermal calculation if you're stacking several breakers side by side.","metaTitle":"Siemens 3RV1031-4EA10-0BA0 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens SIRIUS 3RV1031-4EA10-0BA0 motor protection circuit breaker, 32 A continuous, CLASS 10 trip, 50 kA at 400 V.
