Class I Division 2, Groups C and D rating with encapsulated construction enables safer operation in explosive environments, reducing ignition risk and easing regulatory documentation for chemical plants, refineries, and paint facilities. The EPZ design enhances isolation from the surrounding environment, supporting longer service life and lower maintenance costs in tough factory settings. Aluminum windings contribute to lighter weight and improved heat dissipation, which translates to easier handling, faster installations, and reduced structural requirements on switchgear cabinets. The 480 V primary to 120/240 V secondary configuration supports common control-system and instrumentation loads, while 50/60 Hz compatibility aligns with global electrical infrastructure, improving cross-site deployment. The NEMA 3R enclosure and Weathershield labeling guarantee indoor-outdoor suitability, enabling flexible mounting in equipment rooms or exterior utility spaces without compromising protection. At 0.75 kVA, the transformer delivers sufficient headroom for small-mid sized control panels while helping minimize capital and lifecycle costs. Its compact footprint—5.75 in depth, 12.42 in height, and 10.84 in width—paired with a 33 lb weight simplifies mounting on panels and frames, reducing installation time and labor. The 524H wiring connection supports robust, field-terminations with proven Eaton connection standards, while the fixed taps and absence of secondary adjustments simplify configuration and reduce field error potential. Built-in warranty (one year from installation or 18 months from shipment) provides predictable support aligned with project schedules and service plans.

FAQs
Install as a Class I Division 2, Groups C and D device inside its NEMA 3R enclosure. Mount it on a stable surface or within a rated panel, using the 524H wiring connection. Ensure supply is 480 V primary feeding the 120/240 V secondary, and maintain the environment within the enclosure's indoor-outdoor rating. The unit’s dimensions (5.75 in D, 12.42 in H, 10.84 in W) and 33 lb weight simplify mounting in constrained spaces.
Yes. The transformer is designed for a 480 V primary and a 120/240 V secondary in a single-phase configuration, operating at 50/60 Hz. It uses aluminum windings to optimize thermal performance and energy efficiency for instrumentation and control circuits.
Yes. It features an indoor-outdoor Weathershield with a NEMA 3R enclosure, making it appropriate for both indoor switchgear rooms and outdoor equipment pads in hazardous environments, while maintaining protection from dust, moisture, and contaminants.
The unit is UL Listed, confirming compliance with safety standards for hazardous locations. Its Class I Division 2, Groups C and D design and NEMA 3R enclosure further support regulatory alignment for hazardous-area installations, reducing risk during commissioning and operation and simplifying inspection readiness for regulated facilities.
The warranty follows Eaton’s policy 25-000: one year from the date of installation or eighteen months from the date of shipment, whichever occurs first. This covers manufacturing defects and reliability concerns, providing project planners with predictable maintenance windows and support options for lifecycle planning.
