Indoor-Outdoor
Encapsulated EP design with aluminum windings delivers rugged durability and corrosion resistance, reducing field failures and maintenance costs in harsh environments. This directly improves system uptime for control panels and power-distribution points in factories and outdoor facilities. The NEMA 3R enclosure provides weather protection, enabling safe outdoor installations and flexible siting without compromising performance. For machine controls, the 3 kVA rating at 60 Hz supports consistent voltage delivery to relays, sensors, and logic circuits, improving control reliability and reducing nuisance trips. Tap settings of 2 at +2.5% FCAN and 2 at -2.5% FCBN offer precise voltage regulation under varying loads, mitigating drift and ensuring equipment safety. The 460 V to 120/240 V outputs simplify integration with existing automation modules and legacy equipment, while the 16P wiring connection streamlines harness design and field terminations. A 115 °C rise rating supports continuous operation in hot plants, while UL Listed certification aligns with stringent safety standards. At 66 lb and with compact dimensions, installation fits tight control rooms and outdoor enclosures, reducing installation time and labor costs.
