Description
The Utica-Dunkirk 240005330 Transformer is an electrical component used to convert incoming 120V primary power to a lower 24V secondary output with a 40 VAC rating. It is installed in furnaces, boilers air handlers and other heating and cooling equipment to supply stable, low-voltage control power. It operates as a step-down transformer within HVAC systems’ control circuit enabling thermostats, relays, and safety controls to operate accurately. It serves as a power supply interface between line voltage and low-voltage control circuits, ensuring consistent operation across residential heating and cooling connection systems.
