The encapsulated construction provides protection from moisture, dust, and contaminants typical of industrial environments. Mounting is supported through integrated knockouts and slotted holes for wall hanging. Date code Z0812 and serial number 0014 are visible on the unit nameplate. The transformer is supplied in original Jefferson Electric packaging with internal protective wrap. Job number CH10016 appears on the factory label.
