SIRIUS 3RV2411-1HA15 — Transformer-Protection Circuit Breaker
The Siemens 3RV2411-1HA15 is a SIRIUS-branded circuit breaker designed specifically for transformer protection. It mounts via screw or snap-on onto 35 mm DIN rail per DIN EN 60715, fitting a 45 mm wide footprint — standard for the SIRIUS 3RV2 frame. Rated operating voltage spans 20 to 690 V. Short-circuit breaking capacity reaches 100 kA at 400 V and 240 V, 42 kA at 500 V, and 4 kA at 690 V — figures that define the available fault current this breaker can interrupt without upstream coordination failure. Trip class is CLASS 10, meaning it clears a locked-rotor condition within 10 seconds at 7.2× the thermal setting — the standard for standard-duty motor and transformer starting profiles.
Mounting and Clearance
Fastening method is screw and snap-on mounting onto 35 mm DIN rail according to DIN EN 60715. Mounting position is any. Required clearances: 50 mm upward and downward, 30 mm at the side, 0 mm forward and backward — important for panel layout when stacking multiple breakers. Dimensions: 97 mm depth, 45 mm width, 97 mm height. The 45 mm width matches the standard SIRIUS 3RV2 single-pole-plus-neutral frame, so it occupies one 45 mm slot on a DIN-rail assembly.
Protection and Ratings
Phase failure detection is included — the breaker trips on loss of any phase, preventing single-phasing damage to transformers or motors downstream. Horsepower rating: 1 hp at 230 V. Current ratings at various voltages: 8 A at 480 V and 600 V. Short-circuit protection with gL/gG fuses: 50 A at 400 V, 40 A at 500 V, 35 A at 690 V. Auxiliary contact ratings: 1 A at 24 V, 0.5 A at 120/125/230 V, 0.15 A at 60 V. Maximum switching frequency in AC-3 duty: 15 operations per hour.
Environmental and Wiring
Operating temperature range: -20 to +60 °C. Storage and transport range: -50 to +80 °C. Terminal capacity: 2 × (0.5 to 1.5 mm²) or 2 × (0.75 to 2.5 mm²) solid or stranded. Main contact screw size: M3.
Lifecycle and Sourcing
Lifecycle stage is current production — this is an active catalog item, not phased out or NRND. The 3RV2411-1HA15 is sourced and quoted to order against an RFQ through independent distribution; availability and current pricing are confirmed at quote time.
