ABB’s general purpose single-phase dry type transformers are step-down transformers designed for installations that require a 3-wire secondary voltage for 120/240 V systems. These units can also be used in 2-wire, 120x240 V applications. Their primary voltages are 240x480. Optional wall mount brackets are available for most models. Lug kit and copper ground bar are included.
