FAQs
Begin by selecting a DS-3 or DT-3 enclosure with sufficient clearance for the 23.84 in length, 24.22 in width, and 42.03 in height footprint. Mount the transformer securely to the panel backplane, connect the 380 V primary leads, and wire the 120/240 V secondary outputs to downstream circuits. Verify taps set to the appropriate +2.5% or -2.5% positions, and ensure proper clearance for cooling. Follow UL-listed safety practices and Eaton installation guidelines to complete the setup.
Key specs include a 37.5 kVA rating, single-phase configuration, 380 V primary, 120/240 V secondary, and a 50-60 Hz operating range. Aluminum windings reduce weight and resistance. The transformer offers voltage taps: 2 at +2.5% FCAN and 4 at -2.5% FCBN for voltage adjustment. Temperature rise is rated at 150 °C, and the unit is UL Listed for safety.
Yes. The DS-3 design and totally enclosed non-ventilated construction make it well-suited for panel boards and machine power stages in industrial environments. Its 37.5 kVA rating supports moderate-to-heavy loads, while the 380 V to 120/240 V transformation accommodates control circuits, motors, and automation equipment with reliable voltage delivery and minimal leakage.
The T38M11S37XNV is UL Listed, ensuring compliance with recognized safety standards for electrical equipment. It carries Eaton’s warranty policy of 25-000, offering one year from installation or eighteen months from shipment, whichever occurs first. This warranty supports ongoing reliability and provides a clear benchmark for maintenance planning.
Prioritize solid mounting within a DS-3 enclosure to minimize vibration, allow adequate clearance for cooling, and use voltage taps to maintain stable downstream voltages. Choose the 380 V to 120/240 V configuration aligned with facility loads, and schedule periodic insulation and thermal checks. The aluminum windings and robust enclosure reduce maintenance needs and extend service life, improving overall return on investment.
