SIRIUS S00 direct starter — 45 mm wide, snaps onto 60 mm busbars
The 3RA2110-1BH15-1BB4: It mounts by snapping onto 60 mm busbar systems (the design is explicitly for that busbar pitch), with a vertical mounting position and a 45 mm width that fits standard panel layouts. The control circuit runs on 24 V DC, and the main circuit uses spring-loaded terminals — no screw torque needed, which speeds wiring in production builds.
Panel fit and environmental limits
Dimensions are 155 mm deep, 45 mm wide, 260 mm tall — the 45 mm width is the critical slot dimension for DIN-rail or busbar spacing; the 155 mm depth needs clearance behind the panel door. Clearance requirements: 50 mm upwards, 20 mm forwards, 20 mm at the side, 10 mm downwards — zero backwards clearance means it can sit flush against the backplane. Operating temperature range -20 to +60 °C covers most indoor industrial environments; storage and transport range -50 to +80 °C is wider for cold-chain or desert logistics.
Sourcing and lifecycle — active, quoted to order
It ships as a complete unit: the supplied contactor is 3RT2015-2BB41 and the supplied link module is 3RA2911-2AA00 — no separate ordering of those sub-assemblies needed.
