It includes 2 normally open and 1 normally closed main contacts, plus 1 NO and 1 NC auxiliary contact set. The 220 A continuous rating governs the main power path — sized for a DC drive's armature or field circuit where the braking resistor dumps energy back. The 300 VDC rating means it safely interrupts the DC bus voltage during a dynamic braking event; DC arc extinction is harder than AC, so that 300 VDC figure is the limiting voltage for this contactor's application. The 120 VAC coil voltage is standard for North American control panels running off a 120 V control transformer. The 3-pole configuration (2 NO + 1 NC) lets one pole switch the braking resistor while the other two isolate the drive output or provide a pre-charge bypass — common in DC drive retrofit and decommissioned-line pulls. Mounting type is Device — meaning it's a panel-mount contactor, not a DIN-rail snap-on. The auxiliary contacts (1 NO + 1 NC) are built in, so no separate aux block is needed for status feedback to the PLC or drive controller. The 120 VAC coil ties directly to the control transformer secondary; verify the coil suppression matches the drive's I/O card if the PLC output drives the contactor directly.","metaTitle":"EHDB220C-1L 220A 3-Pole DC Drive Contactor, 120VAC Coil","metaDescription":"EHDB220C-1L 3-pole DC drive dynamic braking contactor, 220 A, 300 VDC, 120 VAC coil.
