Siemens 75LCC277A Lighting Contactor Coil 277V

Siemens 75LCC277A Spare Coil for Class LC Electrically Held Lighting Contactor is a 277V AC coil accessory that powers the control side of Siemens LC lighting contactors. Designed as a replacement coil to energize the Class LC contactor in lighting and heating-load applications, it replaces a failed coil without replacing the entire unit. The coil is specified for 277V at 60 Hz and is also compatible with 240V at 50 Hz systems, reflecting Siemens' multi-voltage LC coil lineup. Catalog number 75LCC277A identifies this coil as the 277V variant within the LC family. Use with Class LC electrically held lighting contactors to switch lighting circuits in commercial, industrial, and institutional environments. When selecting, ensure your system’s control voltage matches 277V 60 Hz (or 240V 50 Hz) and that the host device is a Siemens Class LC lighting-contactor coil assembly. This spare coil option supports quick maintenance—stocking a coil replacement on-site minimizes downtime while keeping the existing contactor and wiring intact. It is part of Siemens’ LC product line that covers a range of coil voltages for varied electrical infrastructures, offering a reliable path for lighting-control installations.
