1 Machine Tool and Control Power Description Type IP transformers are core and coil units designed for machine tool, industrial control, panelboard, and general-purpose applications. These designs are now welded core and encapsulated to provide the highest quality electrical performance. The transformer coil is completely surrounded by epoxy, making the unit impervious to external elements. The lamination core is welded to provide superior quiet performance. Several types of terminations are available to simplify installation. These include primary and secondary leads out, integral fuse, and spade-type terminals and our standard which is a touch proof terminal block. Consult your local GE Sales Office for complete technical applications data. Standards: Type IP units conform to NEMA ST20. They are UL listed under UL-506, File E 2739, and C-UL listed. Insulation Classes: Generally, 150 VA and below are 105 C insulation class, 55 C rise. 200 VA and above are 185 C (NEMA), 180 C (UL) insulation class, 115 C rise. Maximum surface temperature rise is 65 C above ambient. Frequency: 60 Hertz is standard; 50 Hertz is available as an option. Voltage Regulation: All designs 2.0 kva and below are compensated for voltage drop. Generally, this compensation ranges from 10% in the smallest rating to 3% for the largest. All machine tool designs meet or exceed NMTBA regulation requirements. Series-Multiple Secondary Connections: Transformers with 120/240 V secondaries (series-multiple) may be connected for 120 V, 240 V or 240/120 V three-wire. Jumpers are provided. Overcurrent Protection: Type IP transformers are low impedance transformers that require overcurrent protection for most applications. They provide for optional integral primary and/or secondary fusing. Mounting Dimensions: Type IP transformers are lightweight, small, and designed for minimum mounting dimensions. Many units will fit competitors mounting footprints.

9 General Purpose Transformers in Enclosures Dry-Type/Cased Isolated General Purpose Single-Phase General Information The complete family of transformers from GE provide quiet, reliable transformer operation. All of the dry-type transformers through 1,000 kva are UL listed under the requirements of Standard 506 and In addition, each transformer meets the requirements of NEMA ST-20, Type QB, QMS, and QMS 3 models are C-UL listed. General-purpose transformers are rated 600 Volts and below for supplying appliance, lighting, and power loads from electrical distribution systems. Standard distribution voltages are 600, 480, and 240 Volts; standard load voltages are 480, 240, 208, and 120 Volts. The transformer is used to obtain the load voltage from the distribution voltage. Since no vaults are required for installation, these transformers can be located right at the load to provide the correct voltage for the application. This eliminates the need for long, costly, low-voltage feeders.
