The ABB GJL1211001R8015 is an electrical contactor with a 380-415VAC coil rated for 50/60Hz operation. It sits in the Contactors and Starters category, subcategory Electrical Contactors.
Coil voltage and application fit
The coil is wound for 380-415VAC, 50/60Hz. That places it in the standard European three-phase control voltage range. For a panel already running a 400V control transformer, this contactor drops in without a separate step-down. Verify the control circuit voltage matches before committing the BOM line.
