ABB 9T58K2812 General Purpose Transformer

The ABB 9T58K2812 General Purpose Transformer is a 1 kVA, single‑phase control power transformer with an open‑core, encapsulated coil construction (Type IP) and epoxy‑encapsulated windings for moisture and dust resistance. It accepts a 240/480 V primary and provides a 120/240 V secondary, making it well suited to derive low‑voltage control power from common industrial mains in compact panel footprints. This dry‑type unit is designed for industrial and light‑duty loads, including machine tools, industrial control panels, HVAC equipment, signaling and alarm systems, and general circuit isolation, where robust performance and electrical isolation are required. The 9T58K2812 is specified for up to a 100°C rise, aligning with typical CPT TB applications, and its encapsulated open‑core design supports reliable operation in everyday industrial environments while offering straightforward integration into panel wiring and control circuits. In practice, it serves as a dependable source of control voltage for relays, contactors, sensors, and other automation loads, delivering consistent power with the simplicity and ruggedness demanded by industrial applications.
