The 3RA2110-1KS17-1BB4: Designed for snapping onto 60 mm busbar systems, this starter mounts vertically and occupies a 45 mm wide footprint — three units fit in a standard 145 mm DIN cutout, leaving room for a line-side breaker or fuse. Clearance requirements: 50 mm above, 20 mm below, 20 mm to the side, and 20 mm forward — no space needed behind the unit (0 mm backwards). The 155 mm depth fits most 200 mm deep enclosures with room for wiring. The supplied contactor (3RT2017-2BB41) and link module (3RA2911-2AA00) are pre-assembled and tested — no separate wiring between the contactor and overload block, which eliminates a common source of loose-terminal callbacks.
Motor ratings across common voltages
At 400 V AC-3, the starter is rated 12 A, corresponding to 5.5 kW (7.5 hp) — a common size for small conveyors, pumps, and fans. At 230 V it delivers 3 hp, and at 575/600 V it reaches 10 hp. The maximum AC-3 operating voltage is 690 V, and the unit carries an 11 A rating at both 480 V and 600 V — useful for 480 V North American installations and 600 V Canadian industrial plants. Ambient operating range is -20 to +60 °C, with storage and transport limits from -50 to +80 °C — suitable for unheated warehouses and shipping in winter conditions.
The supplied contactor and link module are standard SIRIUS components, so spares are widely stocked.
