Premium 30 Energy Efficient Transformer
Features and Benefits
NEMA Premium Compliant
Complies with NEMA Premium Efficiency Transformer Program specifications.
Energy Efficient
Contributes to LEED® certification through reliable reduction in energy.
Easy to Spec and Install
Mounting dimensions consistent with Square D TP1 and general
purpose transformers.
Safe and Reliable
All Distribution Transformers are tested per NEMA ST-20, NEMA TP-2, and
10 C.F.R. Part 431 (“Test Procedures for Distribution Transformers”) requirements
in a laboratory that participates in UL’s Client Data Test Program (UL File DA643).
Compact Footprint
Three inch clearances from all ventilated openings require less overall installation
floor space compared to the industry standard of six inches.
Intuitive Design
• Routine terminal location and wiring compartment designs meet the National
Electrical Code (NEC) bending requirement.
• Large terminals allow lugs to handle cables of 250% on the primary and 125%
on the secondary.
• Neutral terminals allow cables for 250% of nameplate current – accommodating
loads requiring 200% neutrals.
• Lug kits available in three or five lug packets to easily match cable sizes.
