Industrial T-2A-53313-3S Three-Phase Transformer

ACME T-2A-53313-3S is a 45 kVA three-phase low-voltage distribution transformer that steps a 480 V three-phase supply (primary) down to a 208Y/120 V, three-phase secondary at 60 Hz. This model is specified for North American power systems and is commonly used to derive 120 V and 208 V service from a 480 V feeder, enabling outlets, lighting, controls, and equipment rated for 120/208 V to be powered from a single 480 V source. The 3-phase, 60 Hz design supports balanced loading across phases and is suited for installation in electrical rooms, equipment enclosures, or switchgear arrangements where a dedicated 480 V-to-208/120 V step-down is required. With a 45 kVA rating, it provides ample capacity for a range of loads such as motors, drives, controllers, and power distribution blocks while maintaining stable voltage under typical load profiles. Primary configuration is 480 V delta, while secondary is 208V line-to-line in a 208Y/120 V arrangement, ensuring compatibility with standard 120 V devices and 208 V equipment that accepts a 120 V neutral reference. The part number T-2A-53313-3S identifies this exact 45 kVA, 480 V-to-208/120 V transformer within ACME’s three-phase distribution lineup.
