The Siemens 3RA2110-0AA15-1BB4 is a SIRIUS non-fused load feeder — a pre-assembled direct starter combining a contactor, overload relay, and circuit breaker in one package. Rated for motor starting duty (AC-3) up to 690 V, it integrates a thermal bimetallic overload release (CLASS 10 trip class) and a magnetic short-circuit trip. The 24 VDC coil draws 4 W holding power. The feeder ships with a 3RT2015-1BB41 contactor, a 3RA1921-1DA00 link module, and a 3RV2011-0AA10 circuit breaker pre-wired and tested. An auxiliary switch is available as a product extension.
