  • Features

    Model III unit substations leverage Schneider Electric’s expertise across its medium and low voltage product lines to offer a complete solution for the compact substation market.

    • HVLcc primary switch offers proven performance in a compact foot print.
    • Dry type transformers offered from 75kVA to 1000kVA meeting the latest DOE 2016 standards.
    • Available with either an individually mounted secondary main breaker or Schneider Electric's I-Line distribution panelboard. The I-line panelboard is one of the most flexible and trusted power distribution panels in the industry.
    • Seismically qualified units are available.
    • Branch circuit breakers from 15A to 1200A
    • Available options include digital metering, surge arresters, and surge protective devices (SPD).


    • Lower installation costs: the packed unit substation is easier to handle on-site and the low voltage section is pre-connected when it arrives on-site.
    • Easier site handling: arrives as a single shipment, no need to coordinate multiple product deliveries to job site.


    Model III is ideal for data centers, high-rise electrical rooms, renovations, and new construction where space is at a premium.
