Siemens 3TA2210-0A Contactor

Siemens 3TA2210-0A Contactor is a 3TA22-series power contactor with a 120 V AC coil (60 Hz) and a 30 A main contact rating, configured with two normally open and two normally closed auxiliary contacts. This Furnas Electric Co variant is designed to switch AC loads in control panels and motor circuits, providing reliable operation in industrial automation applications. The unit’s 3-pole main contacts support multiple circuits, while the auxiliary 2NO/2NC contact set provides signaling and interlocking functionality without additional relays. For integration with standard 120 V AC control systems, the coil voltage aligns with typical automation controls, making it suitable for starting and stopping motors, pumps, fans, conveyors, and other equipment in automated process lines. This model is commonly employed in control panels where remote actuation is required by PLCs, timers, or relays, offering a compact, field-proven solution for medium-load switching tasks.
