Unit substation, Mini Power-Zone, bolt on, 25kVA, 1 phase, 480V primary, 120/240V secondary, 18kA, BB

Square D™ brand Mini Power-Zone™ unit substation from Schneider Electric provides the answer to requirements for a portable, compact power supply for small loads. The Mini Power-Zone unit substation uses a separate transformer and panel section. This allows the panel section to be removed and wired first if desired. These transformers can be replaced without disturbing the panel section and associated wiring. The new transformer simply slides into the top of the panel section and primary and secondary leads are reconnected to the main circuit breakers. The panel section uses Square D™ brand QO™ style circuit breakers. Use Qwik-Gard™ circuit breakers for required ground fault protection.
