SIRIUS 3RV2341-4RC10 — Circuit Breaker for Starter Combinations
The Siemens SIRIUS 3RV2341-4RC10 is a circuit breaker designed specifically for starter combinations — meaning it integrates directly into a motor starter assembly, combining disconnect, short-circuit, and overload protection in one device. It mounts via screw and snap-on onto 35 mm DIN rail per DIN EN 60715, in any mounting position, saving panel space and wiring time. Rated 84 A at both 480 V and 600 V, this breaker handles motor loads up to 60 hp at 460/480 V and 75 hp at 575/600 V. The breaking capacity sits at 30 kA at 400 V AC and 65 kA at 400 V AC — the higher figure likely reflects a different test condition or fault level rating, both well above typical industrial fault currents. At 240 V AC it breaks 100 kA, and at 500 V AC it drops to 8 kA, so verify your available fault current at the service voltage. Terminals accept solid or stranded conductors: 2x (2.5 to 16 mm²) for the main circuit, or 1x (10 to 70 mm²) for larger feeds. Operating temperature range is -20 to +60 °C, storage from -50 to +80 °C. No ground-fault or phase-failure detection built in — those functions live in the associated overload relay or motor management system.
Mounting and Clearance
Dimensions are 70 mm wide, 165 mm high, 176 mm deep. Clearance requirements: 150 mm above and below, 30 mm to the side, zero forward or backward. The 176 mm depth means this breaker extends further into the enclosure than a typical compact MCCB — account for it in gland-plate planning and cable bend radius.
Lifecycle and Sourcing
The lifecycle stage is listed as current — meaning Siemens still produces this part as an active catalog item. No end-of-life notification or successor has been issued for this order code. For BOM freeze or long-term planning, this breaker remains a standard line item in the SIRIUS portfolio.
