ABB EHD220 Contactor

ABB Spectrum EHD220 is a high-current drive contactor designed for DC motor drive circuits, delivering reliable switching for demanding industrial power electronics. It carries up to 220 A in its main circuit and withstands up to 600 VDC, making it suitable for switching high-energy DC loads in motor drives and braking circuits. The coil is a 120 VAC control input, enabling direct interfacing with standard control logic without the need for additional power conversion. The EHD220 sits within ABB’s Spectrum drive-contactor lineup, a family of components intended for integration with ABB drive systems and other power-control equipment. This model is commonly used for DC bus switching in motor drives and for controlling high-current DC loads in manufacturing, material handling, and process automation environments. When selecting a drive-contactor, ensure the coil voltage matches the control circuit (120 VAC in this model) and that the main-connection ratings are compatible with the load current and the maximum DC voltage present in the system.
