Issue:
Can you put the QO-VH or QOB-VH breakers in a Mini Power-Zone (MPZ) indoor/outdoor packaged power supply?
Product Line:
LV Transformers
Environment:
Applies to Mini Power Zone (MPZ) products by SquareD/Schneider Electric
Cause:
QO-VH Breakers are available that have high (22K) AIC levels
Resolution:
While the QO-VH breakers can physically be installed in the Mini Power-Zone (MPZ), there is no valid technical reason to do so. The High AIC rated Mini Power-Zone's are only for the primary breaker that feeds the transformer. The MPZ is a UL listed device in which the available peak let through current of the transformer with an infinite source is less than 10,000 amps. Thus, only 10kAIR rated QO and QOB breakers are required. Anything else is simply a waste of the customer`s money.
