Mini Power-Zone®

Class 7440 / Refer to Brochure 7440BR9401

Sealed Mini Power-Zone® Transformers

Square D® Mini Power-Zone® power supply from Schneider Electric provides the answer to requirements for a portable, compact power supply for small loads. Because the Mini Power-Zone is furnished as a complete package, considerable savings in installation time and costs can be realized. Its NEMA 3R enclosure is suitable for both indoor and outdoor use. The transformer is copper wound, 115° C rise, and epoxy-resin encapsulated. The panel section has copper bus and uses Square D QO® style circuit breakers.

Mini Power-Zone centers are furnished with factory-installed primary main and secondary main circuit breakers only. Circuit breaker ratings are selected to meet National Electrical Code requirements and to coordinate with transformer magnetizing inrush current. Feeder circuit breakers are standard QO plug-on type which should be ordered, as required, from your local Schneider Electric distributor's stock. If ground fault protection is required, Qwik-Gard® circuit breakers may be used in all sizes. Tandem breakers are not permitted.

The Mini Power-Zone uses a separate transformer and panel board section. This allows the panel section to be removed and wired first if desired. Also the transformer 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.
