ABSTRACT:
The inventions solves the problem of convenient mounting of parts of controllers, and solves the problem of interchangeability of vacuum and air break contactors within a controller. A controller has a housing, an isolation switch mounted within the housing, a contactor mounted within the housing and connected electrically downstream from the isolation switch, and the controller has a receptacle which can accept either a vacuum contactor or an air break contactor. Also, the contactor has an operating coil and control components mounted on a side facing a door of the housing so that the coil can be replaced and the control components serviced without disturbing the contactor.
