Square D 9070T250D15 Industrial Control Transformer
The Square D 9070T250D15 is a 250VA single-phase industrial control transformer from Schneider Electric’s 9070 T Series — engineered for demanding machine tool, motor starter, solenoid, and relay control circuit applications. Low-impedance copper windings provide excellent voltage regulation under load, while the transformer’s design accommodates the high inrush currents associated with contactors, starters, solenoids, and relays without nuisance tripping or voltage sag.
Voltage Configuration
The 9070T250D15 accepts a dual-voltage primary of 240V or 480V (series/parallel jumper selectable) and delivers a dual-voltage secondary of 24V or 120V. This flexible configuration makes it suitable for a wide range of North American industrial control circuit voltages without requiring separate transformer models. Primary and secondary connections are made via screw clamp terminals for reliable, tool-assisted termination.
