Description

Designed to operate strictly as a disconnect, this 800-amp three-pole component ensures safe manual switching for industrial applications. The bolt-on configuration installs easily into classic Westinghouse motor control centers and PRL4 panelboards without requiring modern adapters. Delivering a 30kA withstand rating at 480VAC, this legacy M-frame switch provides reliable isolation. Facility managers often utilize this exact match before transitioning to the newer MDL3800K series.
