The Siemens 3RA1110-1GD15-1BB4 is a SIRIUS non-fused load feeder configured as a direct starter, size S00, rated 2.2 kW at 400 V AC. It integrates a contactor, a bimetal overload relay, and a circuit-breaker for short-circuit protection into a single, pre-assembled unit that snaps onto a DIN rail.
The 2.2 kW rating at 400 V defines the maximum motor load this feeder can switch under AC-3 duty. The insulation voltage is rated 690 V. The depth of 128 mm includes clearance for wiring and the supplied busbar adapter.
