Abstract: The present invention provides a single housing assembly for a reduced voltage motor starter assembly. The housing assembly has a medium voltage compartment and a low voltage compartment. In this configuration the housing assembly ins structured to enclose both the medium voltage portion and the low voltage portion of the starter assembly.

Abstract: A contactor for connecting a medium voltage load, such as a medium voltage three-phase motor, to a medium voltage electrical source, such as a medium voltage three-phase electrical source, and for providing protection functionality for the load includes one or more electrical conductors each having separable contacts such that the load is selectively electrically connected to the source, and one or more current transducers each operatively coupled to a respective one of the electrical conductors for measuring a current thereon. A processor is in electronic communication with the one or more current transducers, and a memory is in electronic communication with the processor. The memory stores one or more routines executable by the processor that are adapted to perform one or more protection functions for the load based on the current measured by each of the one or more current transducers and to selectively open and close the separable contacts of each of said electrical conductors.
