Breaking capacity is the headline selector here. At 240 V AC it interrupts 100 kA; at 400 V AC, 50 kA; at 500 V AC, 8 kA; and at 690 V AC, 5 kA. For a 400 V panel with a high-fault utility feed, the 50 kA SCCR gives headroom without needing a current-limiting upstream fuse — that simplifies coordination studies. The AC-3 voltage ceiling is 690 V, so it handles 690 V motor circuits within the 5 kA fault limit. Three poles for the main current circuit, screw-type box terminals on the main side, separate screw terminals for auxiliary and control wiring. Any mounting position is allowed. Zero clearance required at the back or sides for heat dissipation. Wire range is generous: solid conductors accept 2x (2.5 to 16 mm²); stranded accepts 2x (10 to 50 mm²) or 1x (10 to 70 mm²). Finely stranded with core-end processing accepts 2x (2.5 to 35 mm²) or 2.5 to 50 mm². AWG equivalents for main contacts: 2x (10 to 1) or 1x (10 to 2). That covers most panel-building wire gauges up to 70 mm². ## Environmental and Protection Shock resistance rated at 25g for 11 ms. RoHS compliance date is July 1, 2006, so it meets the original EU RoHS directive. No ground-fault or phase-failure detection built in — those functions remain external to this breaker.","metaTitle":"Siemens 3RV1341-4LC10 SIRIUS Circuit Breaker, 90 A, 45 kW at","metaDescription":"Siemens SIRIUS 3RV1341-4LC10 circuit breaker for starter combinations. 90 A continuous, 45 kW at 400 V, 50 kA breaking capacity.
