Westinghouse A202K3CZ3Z Lighting Contactor

The Westinghouse A202K3CZ3Z is a 100 Amp, 600 VAC magnetic lighting contactor with a 277 V coil, designed to remotely switch and control lighting circuits and other electrical loads in commercial and industrial power distribution systems. This 3-pole device operates at 50/60 Hz and uses an industrial-grade electromechanical construction, intended for panel or enclosure mounting in lighting control panels, commercial buildings, and automation systems to provide dependable load switching for lighting and related circuits. It supports operations in offices, warehouses, manufacturing facilities, schools, hospitals, and parking structures where reliable remote control of lighting loads is critical to maintain operational efficiency and system protection. Maintenance teams, electricians, and system integrators typically employ the A202K3CZ3Z for lighting control replacement, power switching upgrades, and ongoing electrical maintenance; common replacements include Eaton A202 Series Lighting Contactor, Allen-Bradley Bulletin 500 Lighting Contactor, and Siemens Lighting Contactor.
