FAQs
Plan for a secure mounting using the 179 frame, allow clearance for cooling, and connect using the 16D wiring configuration. The NEMA 3R enclosure provides weather protection, so place the unit to minimize exposure to direct streams while ensuring accessible taps and terminations for maintenance.
The transformer provides 7.5 kVA with a 380 V primary and 120/240 V secondary, operating at 50-60 Hz in a single-phase configuration. It includes taps at +2.5% FCAN and -2.5% FCBN, enabling voltage regulation under supply fluctuations and aiding precise load planning for mixed equipment.
Yes. The S38D11S07X uses a NEMA 3R enclosure suitable for indoor-outdoor service, offering weather and dust protection. This makes it ideal for outdoor pad-mounted or semi-enclosed applications and reduces the need for frequent enclosure-related maintenance.
The transformer is UL Listed, which confirms electrical safety and compliance with recognized standards. The aluminum winding and EP encapsulation further support durability and reliability in industrial settings. Enclosure rating and warranty terms also reinforce reliability for procurement and compliance teams.
The S38D11S07X carries a one-year warranty from installation or 18 months from shipment, whichever comes first. Its encapsulated EP design and aluminum windings reduce oil leakage risk and maintenance frequency, delivering lower total cost of ownership in ongoing operations.
