FAQs
For installation, ensure a clean, dry mounting surface with adequate clearance for a 5.75 in by 11.28 in footprint. Use proper enclosure protection and terminate wiring with the 536B connection, taking into account 480 V primary and 208 V secondary. The NEMA 3R enclosure supports indoor-outdoor service, reducing the need for additional weatherproofing.
Yes. The unit is designed for 60 Hz operation with a 480 V primary and 208 V secondary, single-phase configuration. This makes it suitable for panel boards, automation controllers, and OEM equipment that rely on 480/208 V electrical architectures.
It is ideal for control panels, automation racks, and OEM equipment requiring compact, rugged power conversion. Its 0.5 kVA rating supports small-to-moderate control loads, while the NEMA 3R enclosure allows indoor-outdoor deployment in factories, warehouses, and outdoor electrical rooms.
The transformer is UL Listed and features a NEMA 3R enclosure, designed for indoor-outdoor service. This combination supports regulatory compliance for many industrial and commercial installations and aligns with typical safety and reliability requirements in automation projects.
With a robust encapsulated design, aluminum windings, and a compact footprint, maintenance is minimized and lifecycle reliability is enhanced. The UL listing and rugged enclosure reduce downtime risk, while a 0.5 kVA rating aligns with efficient power distribution, supporting faster ROI in panel builds and retrofits.
