3-Pole Luminaire Disconnect Kit is for servicing electricians, and includes two male/line half and two female/load half of the luminaire disconnect polybagged with installation instructions. Oversized electrical contacts improve conductivity and reduce temperature rise, while the integral wire leads to an easy installation. A fool-proof design enables mating halves to be installed in only one way. Contacts made of tin-plated brass. The finger-safe line side prevents installer from touching hot contacts. Rounded compact design is small enough to be used in compact applications, as it fits through 1/2" knockout.
