It includes phase failure detection but no ground fault detection, so it handles the most common motor fault — a lost phase — without nuisance tripping on leakage. The 3RV1031-4HB15 delivers 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. At 400 V — the most common industrial supply in Europe and Asia — 50 kA SCCR gives you headroom for high-fault panels without needing a current-limiting upstream breaker. Compared to the 3RV2021-4NA25, which is a newer SIRIUS 3RV2 frame with a different trip curve and higher breaking capacity at 690 V, this 3RV1 series part is the established choice for 400 V distribution where the 50 kA rating is sufficient. The 3RV2 has a slightly different footprint — verify DIN rail spacing if swapping. Width is 55 mm, height 140 mm, depth 149 mm — plan your gland plate and wireway clearance accordingly. Main circuit terminals accept solid 2x (0.5...1.5 mm²) and 2x (0.75...2.5 mm²), or stranded 2x (0.75...25 mm²) and 1x (0.75...35 mm²). Auxiliary and control circuit terminals are screw-type. AWG equivalents for main contacts: 2x (18...2), 1x (18...2). Substance prohibitance date of 07/01/2006 aligns with RoHS compliance. Storage temperature range -50 to +80 °C, operation -20 to +60 °C, transport -50 to +80 °C. Shock resistance rated at 25g / 11 ms.","metaTitle":"Siemens 3RV1031-4HB15 SIRIUS Motor Protection Circuit Breake","metaDescription":"Siemens 3RV1031-4HB15 SIRIUS motor protection circuit breaker, 22 kW at 400 V, Class 20, 50 A continuous, 50 kA breaking capacity.
