Sealed, Mini Power-Zone™ Unit Substation The Square D™ brand Mini Power-Zone ™ unit substation from Schneider Electric provides the answer to requirements for a compact unit substation at low amperage ratings.. This complete package yields considerable savings on floor space, installation, and overall cost. NOTE: Mini Power-Zone unit substations are UL 1062 Listed File E92978 design in a Type 3R enclosure allowing for indoor or outdoor applications. Designed for wall mounting, the unit substation leverages Schneider Electric components integrated into one device. • Epoxy resin encapsulated low voltage transformer • H-frame main circuit breaker • Secondary main circuit breaker • Square D panel board or load center allowing for QO™ or QOB™ branch circuit breakers New MPU solution leverages the latest load center interiors, giving customers more flexibility for branch circuit requirements. Additionally design with a tiered dead front construction. The first dead front allows access to the secondary main circuit breaker, distribution panel board, and the second dead front. The second dead front allows access to the primary main circuit breaker and incoming voltage connection points.
