PZC Transformer Enclosures

Power Zone Center house is installed over the standard ventilated units to provide additional security and environmental protection.

Type 3R enclosure Option No, 1 constructed of 304 stainless steel for corrosive protection.

Designed to allow energy efficient transformers to be installed in environments requiring more protection.


Type 3R enclosure Option No. 2 constructed of painted galvanized for safety

Designed to allow energy efficient transformers to be secured with a padlockable handle for security, which is ideal for school yards.


PZC transformer enclosures are shipped separately from transformers so they can be pre-installed on the job site.

Four standard enclosures of each type material are available for installation of transformer enclosure types D and H.

Drawings are in the Classic Technical Library. Search by catalog number, which is the same as the drawing number.
