ABB EHDB280C-YL AC Contactor 4 Pole 24V Coil Type

ABB EHDB280C-YL is a high‑current drive contactor from ABB's EHDB family, engineered to switch motor‑drive loads with a 24 V DC coil. The model implies a substantial main current rating (280 A) and is documented in ABB literature and distributor listings as part of the EHDB drive contactor lineup, which exists in multiple pole configurations. This variant is specified with a 24 V DC input coil, confirming the coil type and control voltage for this device. EHDB drive contactors are designed for demanding DC drive applications, such as motor control panels and inverter‑based systems, where reliable isolation and fast switching of heavy loads are essential. When selecting a unit, match the coil voltage (24 V DC) to the control circuit and verify the applicable pole configuration and current rating for your load, while confirming NO/NC voltage ratings and any dynamic braking requirements as defined in ABB’s drive contactor specifications.
