What it is

The catalog number is on the transformer nameplate inside the enclosure. Photograph the nameplate, the open interior with the main breakers visible, and the outside of the enclosure so we can judge rust and door condition.

How to read a Square D Mini Power-Zone mini power center catalog number.

MPZ is the Mini Power-Zone with a plug-on QO branch interior. MPZB is the bolt-on branch version. Next is the kVA, then S for single-phase or T for three-phase, then a voltage code: 40 is 480 V to 120/240 single-phase and 2 is 480 V to 208Y/120 three-phase on these units. The F that follows is the class 180, 115 C rise insulation code. A trailing 25K marks a 25 kA interrupting rating.

What drives the number
  • Complete units with both main breakers and the interior intact are worth more than stripped shells.
  • Branch breakers left in the interior add value. QO plug-on breakers are common and easy to resell.
  • Bolt-on MPZB units and 25 kA versions are less common than the standard MPZ.
  • Outdoor units with rusted enclosures still sell for the transformer and breakers.
  • We do not publish prices. Metal, demand, and condition move them. You get a written number for your unit.
From the yard

The Mini Power-Zone is a whole package, so a unit missing its FAL primary main or QO secondary main is quoted as parts. The voltage code on these does not match the general purpose line: a three-phase 480 to 208Y/120 Mini Power-Zone uses 2 where an EE or EXN uses 3. Do not cross-reference the two by code alone. Units pulled from parking lot lighting or temporary power often come back with weathered doors but sound transformers.
