Federal Pacific PSI/II Pad-Mounted Switchgear is designed to meet the switching and isolating requirements of electrical distribution systems with 15 pre-engineered switching configurations. There are UL®-listed standard units available to cover almost every situation – radial feed, loop feed and manual primary-selector switching. Special configurations and designs are available upon request. The three-time fault-close ratings, with the laboratory and field-proven Auto-jet® system can solve both your “near substation” high fault-current and mid-point loop switching applications as well as “distant end-point” standard fault-current requirements.

Installations with concentrated loads can now be served from a single switchgear assembly. The six-compartment configurations require less land space than two four-compartment units, which was the only choice in the past. In addition, the 6-compartment units are more economical than two four-compartment units both in initial and installed costs. There is no sacrifice in operating flexibility and as a result, an outage on the main-feeder cable can be readily isolated and sectionalized. For 8-compartment designs, consult the factory.
