ABB CCT75-480-120 Industrial Motor Starter Assembly

ABB CCT75-480/120 is a 75 VA control transformer designed for ABB combination starters and enclosed motor-starter assemblies. It provides a 120 VAC control supply from a 460–480 VAC line to power coil circuits for contactors and overload relays within 480 V motor-start configurations. This transformer is part of ABB's family of 75 VA control transformers and is typically specified when a 120 VAC control circuit is required in a 460–480 VAC system. Key specifications include a 75 VA rating, primary voltage 460–480 VAC, and secondary voltage 120 VAC. The unit is intended as a starter accessory to be used with ABB starter components, enabling compact, integrated motor control in industrial panels. In ABB catalogs, alternate primary voltages are available in the same 75 VA family (for example 208/120, 240/120, and 600/120), allowing selection to match the system supply. Common applications include machine control panels, conveyors, pumps, fans, and other 480 VAC motors that require a dedicated 120 VAC control supply for relays and control devices. When selecting a transformer, ensure the primary voltage matches the power source and that the 120 VAC secondary is compatible with the control circuitry in your ABB starter assembly.
