Selling Policy 25-000 - Distribution and Control Products and Services
Feature → Business Impact → Application: Totally enclosed non-ventilated design reduces cooling needs and enclosure heat management, enabling simpler installation in compact or crowded control panels and substations. This translates to lower energy use and higher reliability for machine controls and distribution blocks in manufacturing environments. Feature → Business Impact → Application: 75 kVA single-phase transformer with 480 V primary and 120/240 V secondary supports mid-load feeder duties and machinery feeding with clean, regulated power. Ideal for control panels, motor starters, and machine tools where precise voltage regulation matters for uptime and performance. Feature → Business Impact → Application: Aluminum windings and DS-3 frame 814N provide corrosion resistance and structural robustness, improving service life in harsh industrial settings and reducing maintenance intervals for long-term equipment reliability. Feature → Business Impact → Application: Tap settings of 2 at +2.5% and 4 at -2.5% enable fine voltage adjustment to compensate for line drop and voltage fluctuations, reducing nuisance trips and protecting sensitive electronics across varied supply conditions. Feature → Business Impact → Application: Compact footprint with dimensions of 33.97 in L / 62.91 in H / 29.97 in W and a 1271 lb weight balances installation practicality with required thermal capacity, making it suitable for panel rooms and service enclosures in factories and facilities. Feature → Business Impact → Application: UL Listed certification and Eaton warranty policy provide safety assurance and supplier accountability, supporting regulatory compliance, risk management, and faster project approvals for industrial build-outs.

FAQs
Yes. The T48M11S75NV is specified as a DS-3 design, and its Totally Enclosed Non-Ventilated construction is well-suited for narrow or enclosed panels where external cooling is limited. When planning installation, verify panel dimensions (33.97 in L, 62.91 in H, 29.97 in W) and weight (1271 lb) to ensure proper mounting clearances and support.
Key specs include a 75 kVA rating, single-phase configuration, 480 V primary and 120/240 V secondary, 60 Hz, aluminum windings, and a 150°C rise. Taps are provided: 2 at +2.5% FCAN and 4 at -2.5% FCBN, enabling voltage adjustment to accommodate line drop and load variations.
Ideal for machine tooling, control panels, panel boards, and general distribution in manufacturing and facilities. The DS-3 design and 480 V to 120/240 V outputs support motor control, instrumentation, and power distribution in spaces where reliability, compact footprint, and simplified cooling are priorities.
The unit is UL Listed, providing recognized electrical safety certification. Warranty follows Eaton's policy 25-000, offering one year from installation or eighteen months from shipment, whichever occurs first, helping mitigate long-term maintenance risk.
Account for its dimensions and weight (33.97 in L, 62.91 in H, 29.97 in W; 1271 lb) in room and rack layouts, and ensure compatible mounting and electrical connections for 480 V to 120/240 V distribution. Aluminum windings offer corrosion resistance, reducing maintenance needs in damp or industrial environments.
