The Cutler-Hammer C340EG control transformer provides a 0.225 kVA (225 VA) rating with a 480 V primary and a 120 V secondary, enabling a 480 V-to-120 V step-down for industrial control circuits. It is used to supply low-voltage power to control devices such as relays, contactors, and solenoids within electrical panels, machine controls, and automation enclosures. With this fixed primary/secondary arrangement, the C340EG delivers a reliable source of 120 V control power from a 480 V mains supply, supporting standard control logic and signaling applications in industrial environments.
