Breaking capacity is 100 kA at 240 V AC, 50 kA at 400 V, 10 kA at 500 V, and 4 kA at 690 V — so it'll handle a stiff fault on a 400 V distribution board without welding its contacts shut. The 50 A continuous rating and 22 kW at 400 V tell you this breaker is sized for a motor drawing around 50 A full load — typical for a 22 kW four-pole induction motor on 400 V three-phase. Power dissipation runs 29 W hot at rated current, or about 9.7 W per pole. That's heat that has to leave the enclosure — factor it into your panel thermal calculations, especially if you're stacking several breakers side by side. Zero clearance needed at the sides or back, so you can butt it against other devices without derating for air gaps. Dimensions: 55 mm wide, 140 mm tall, 149 mm deep. That 149 mm depth includes the screw terminals and any protruding wiring — check your enclosure depth before committing, especially if there's a door-mounted HMI or disconnect behind it. Wire capacity is generous: solid conductors up to 2x 16 mm², stranded up to 2x 25 mm² or 1x 35 mm² with a ferrule. That covers most motor feeder cables up to 50 A without needing oversized lugs. IP20 on the front — finger-safe touch protection, so it's fine in a closed panel but not washdown-rated. Keep it dry. Shock rated at 25 g for 11 ms — it'll survive a forklift bump to the panel or a nearby press hitting the floor. The auxiliary switch option is available as a field-addable accessory — the breaker is designed for it (product extension auxiliary switch: Yes). No need to order a different base unit if you later add signaling.","metaTitle":"Siemens 3RV1031-4HA10 SIRIUS Motor Protection Circuit Breake","metaDescription":"Siemens 3RV1031-4HA10 SIRIUS motor protection circuit breaker, 50 A continuous, 22 kW at 400 V, Class 10 trip, 100 kA breaking at 240 V.
