It handles motor starting duty at up to 15 switching cycles per hour in AC-3 service, with a Trip Class 10 characteristic that clears overloads fast enough to protect standard induction motors from heat damage during stalled-rotor conditions. This breaker carries a short-circuit breaking capacity of 100 kA at 240 V, 30 kA at 400 V, 6 kA at 500 V, and 2 kA at 690 V. At 400 V — the most common industrial distribution voltage — a 30 kA SCCR means it can safely interrupt a fault up to that level without welding contacts or cascading failure upstream, so it coordinates with most 400 V switchgear rated for 36 kA or higher. ## Deployment context — where this part lives in the panel The screw-type main terminals accept 2x 1…25 mm² or 1x 1…35 mm² solid or stranded copper — sized for motor feeders up to around 7.5 kW at 400 V. Operating temperature range of -20 to +60 °C means it survives inside a non-air-conditioned enclosure near a kiln or compressor; storage range of -50 to +80 °C covers transport and warehouse extremes.","metaTitle":"Siemens 3RV2131-4TA10 SIRIUS Motor Protection Circuit Breake","metaDescription":"Siemens 3RV2131-4TA10 SIRIUS motor protection circuit breaker, Class 10 trip, 30 kA SCCR at 400 V, screw terminals, DIN rail mount.
