The ABB EHDBRC280-1 is a 120 VAC 60 Hz replacement coil, designed for use in ABB contactors and motor starters where the original coil has failed or the line voltage requires this specific pickup rating.
Because this is a coil replacement, the only functional parameter that governs fit is the coil voltage and frequency: 120 VAC at 60 Hz. Verify that the contactor or starter frame accepts this coil — the mechanical interface is specific to the ABB device series it was designed for.
What the 120 VAC 60 Hz rating means for the buyer
The 120 VAC 60 Hz coil rating is the pickup voltage and frequency the coil is wound for. On a 60 Hz supply, the coil impedance is tuned for that frequency.
