Abstract
A medium voltage controller for electrical equipment, having cast fuse holders, a disconnect switch, a switch illuminator, low power current transformers, and an optical temperature measuring system. The fuse holder includes a cast housing with smooth rounded surfaces that reduce corona. The disconnect switch has cast components that provide terminal points, mounting surfaces, and contact surfaces. The switch illuminator provides illumination of the disconnect switch internals. The contactor assembly is mounted in a truck and moves on a rail system that includes a pull-down handle with rails. The truck rolls out of the cabinet on the extended rails for easy removal from the cabinet. The truck, and contactor assembly, is racked in by pushing the truck into the cabinet and then raising the handle, which forces the draw-out fingers to engage the contact stabs.
