What this SIRIUS starter delivers
The 3RA2110-1GD15-1AP6 is a SIRIUS non-fused direct starter — a pre-assembled combination of a 3RT2015-1AP61 contactor, a thermal bimetallic overload relay, and a busbar adapter (8US1251-5DS10) in a single Size S00 package. It snaps onto 60 mm busbar systems in a vertical mounting position, saving panel space compared to building the same circuit from discrete components.
Motor ratings across common line voltages
At 400 V AC-3, the unit is rated for 2 200 W (roughly 3 hp) — that is the continuous motor load it can switch and protect in a typical 400 V three-phase network. At 480 V the current rating is 4.8 A; at 600 V it steps to 6.1 A — the higher voltage allows a slightly higher current before the thermal element reaches its trip threshold. Horsepower equivalents span from 0.25 hp at 110/120 V up to 5 hp at 575/600 V, covering fractional through small integral motor branches in North American and European supply systems.
Panel footprint and integration
At 45 mm wide × 200 mm tall × 155.1 mm deep, the Size S00 package fits into a standard 200 mm deep enclosure with room for gland plates and wiring ducts on both sides. Clearance requirements: 20 mm upwards, 10 mm downwards, 9 mm at the side — no extra space needed forwards or backwards, which simplifies rail layout in crowded panels. Rated for degree of pollution 3 and operating temperatures from -20 to +60 °C, so it holds up in industrial environments with conductive dust or condensation cycles.
