Siemens 3RA1120-1FA24-0BB4 Starter Combination

Siemens 3RA1120-1FA24-0BB4 Starter Combination is a 460-volt motor starter assembly designed for direct-on-line starting of three‑phase industrial motors up to 7.5 HP, combining a motor starter with overload protection in a compact, ready-to-wire unit. The device integrates a motor starter with overload relay and an auxiliary contact set (1 NO + 1 NC), with screw‑type terminals for the main current circuit and for auxiliary/control wiring. Designed for use in control cabinets, it belongs to Siemens' SIRIUS 3RA family of motor starter combinations and is intended to simplify wiring while delivering reliable protection. Typical configurations support starting small to midsize motors in applications such as conveyors, pumps, fans, and machine tools where 460 VAC direct‑on‑line starting is appropriate.
