PMX Modular Metal-Enclosed Switchgear is offered in manual, remote supervisory, and source-transfer versions.

In source-transfer applications, the entrance modules are provided with power-operated switches and an S&C Micro-AT® Source-Transfer Control.

In remote supervisory applications, the entrance modules are provided with power-operated switches and an S&C 5802 Automatic Switch Control, which provides sophisticated RTU functionality and supports a variety of user-specified communication devices. Alternately, a user-specified RTU can be furnished.

Entrance and feeder modules can be furnished with Type SM-20, SM-4Z, SM-40, or SM-5S Power Fuses or Fault Fiter® Electronic Power Fuses. These modules can be provided with an enhanced fuse handling option featuring S&C’s patented TransFuserTM Mountings. Each mounting effortlessly unlatches and pivots to the open position, making the de-energized and isolated power fuse accessible for replacement.

All modules can be furnished with optional barriers that separate the cable termination sections from the main bus and switching sections.
