ABB DC Drive Contactor EHDB110

Used in solid state DC adjustable speed drive systems, the ABB Spectrum EHDB110 is a 3-pole DC drive contactor rated for 110A continuous current at 600 VDC. The unit carries the ABB Spectrum "Drive Contactor" designation and is designed for applications where the contactor is not required to make or break the load under normal operating conditions. The coil is rated at 110V AC at 50Hz and 120V AC at 60Hz, as confirmed by the visible nameplate. Terminal markings visible on the unit include poles 1 through 4 on the main contacts, with 5(+) and 6(-) designations consistent with the EHDB series polarity-dependent NC contact configuration used for dynamic braking circuits. An auxiliary contact block is mounted to the unit, marked CAL 16-11A, rated 600V AC and 10A per the visible label. The full catalog reference visible on the back label reads EHDB 110C. UL and CSA listings are confirmed by visible marks on the nameplate. ABB positions the Spectrum EHDB series as a purpose-built solution for solid state DC drive environments, where standard AC contactors are not suitable due to DC arc interruption requirements.
