General Electric 9T58K4357 Industrial Control Transformer

General Electric 9T58K4357 Industrial Control Transformer is a 1.0 kVA, single-phase transformer with a 240 V primary input and a 120 V secondary output. Built by GE, this model (part number 9T58K4357) is designed to supply control circuitry in industrial equipment, providing an isolated source of low-voltage power for relays, timers, sensors, and other control devices inside electrical panels. The 1.0 kVA rating handles modest control loads, while the 1-phase configuration simplifies integration into standard 240 V power circuits found in many industrial settings. Its rugged construction and 240 V-to-120 V configuration align with common control-power practices, reducing the need for additional circuitry and maintaining separation between the main power circuit and control circuitry. This transformer is intended for panel builders and maintenance technicians requiring a dedicated control power source for reliable operation of control devices in industrial applications.
