Cutler Hammer-Eaton A200MACAC 3-Pole Contactor 9A 120V

The Cutler-Hammer Eaton A200MACAC 120V 9A 3Pole Contactor is an electrically actuated switch intended for use in HVAC systems. It regulates the flow of electricity to different components in a manner similar to a heavy-duty relay. When powered, a contactor's internal contacts close by means of electromagnetism, enabling current to flow through the circuit and power devices such as pumps in hydronic heating systems, compressors in chillers, and motors in air handlers. On the other hand, de-energizing the contactor cuts the electricity supply, shutting off the machinery. This contactor is ideal for applications needing coordinated control of several components because of its 3-pole architecture, which allows it to simultaneously control three distinct circuits. Its 9A capacity and 120V rating also guarantee compatibility with a range of low-voltage HVAC devices.
