Hammond Power Solutions SH3T0225KB3S - 3-Phase Transformer 225kVA 480D-208Y/120V

SH3T0225KB3S

Hammond Power Solutions SH3T0225KB3S is a three-phase general duty transformer designed for industrial power distribution applications. This unit features a 480V delta primary configuration with multiple voltage taps and delivers 208Y/120V secondary power through a zig-zag connection with neutral, providing effective K-rated performance with 225 kVA standard capacity and 244.84 EKVA. The transformer is housed in a Type 3R/IP24 rated enclosure with ANSI 61 grey finish, measuring 52 inches high by 37.5 inches wide by 34 inches deep, and operates with a 150°C temperature rise using 220°C insulation class materials. It complies with multiple efficiency standards including DOE 2016, NRCAN 2019, and NMX 2021, features seismic certification per IBC 2018 (Sds=2.0), and maintains a sound level of 58 dBA. Typical applications include industrial facilities, commercial buildings, and institutional power systems requiring reliable three-phase power conversion with robust environmental protection.
