Eaton RT12M12F2116CU Ventilated Transformer - UL
Part Number: RT12M12F2116CU
Quick Summary
The Eaton RT12M12F2116CU is a general purpose ventilated transformer for marine-duty power distribution. In harsh industrial environments, uptime and reliability are non-negotiable, and equipment must tolerate vibration, moisture, and temperature swings. UL Listed, ABS Certified, and DOE 2016 Efficient conformance signal strong regulatory readiness and long-term cost savings. This design uses copper windings and a 60 Hz, 120 V primary to deliver 22.5 kVA with selectable taps (+2.5%, -2.5%), enabling precise voltage regulation. The rugged enclosure, frame 818, and WS11 weather shield provide installation flexibility and lower maintenance needs.
