An industry standard for industrial control power transformers Control power transformers are designed with low impedance windings for voltage regulation, and can accommodate the high inrush current associated with contactors, starters, solenoids, and relays.

120 V power for auxiliary or isolated loads Transformer disconnects provide a source of 120 V power for auxiliary or isolated loads, such as panel lighting, portable power tools, and programmable controller equipment.

Used for measurement and control of distribution equipment Available in multiple window sizes and configurations to maximize applications. Square D offers 3 models of voltage transformers.
