Overview
The Brad Harrison 32638 is a reliable 3-pole quick-change molded connector designed for industrial motor disconnect and reconnect applications. This connector eliminates the need for hardwiring when replacing fractional to 5HP motors on pumps, conveyors, cooling fans, grinders, saws, and other equipment. The molded construction and quick-change design enable fast, safe electrical connections while protecting against water, dust, oil, and other contaminants in harsh industrial environments.
