Type AP Transformer
Product Description■ Resin-encapsulated designs
Application DescriptionTransformers provide stepped down voltages to machine tool control devices enabling control circuits to be isolated from all power and lighting circuits. This allows the use of grounded or ungrounded circuits that are independent of the power or light-ing grounds; greater safety is afforded the operator. The control transformer line is particularly adaptable on appli-cations where compact construction is demanded.
Features, Benefits and Functions■ UL recognized ■ Resin encapsulated■ 60 Hz operation■ 115°C winding rise■ Convenient screw-type terminal
board■ Bottom or side/wall mounting
designs■ Performance meets/exceeds
requirements of ANSI/NEMA ST-1■ Regulation exceeds ANSI/NEMA
requirements for all ratings
Standards and CertificationsIndustry StandardsAll Cutler-Hammer dry type distribution and control transformers are built and tested in accordance with applicable NEMA, ANSI, and IEEE Standards.
Product SpecificationsOverload CapabilityShort-term overload is designed into transformers as required by ANSI. Dry type distribution transformers will deliver 200% nameplate load for one-half hour; 150% load for one-hour; and 125% load for four-hours without being damaged provided that a con-stant 50% load precedes and follows the overload. See ANSI C57.96-01.250 for additional limitations.
Continuous overload capacity is not deliberately designed into a trans-former because the design objective is to be within the allowed winding tem-perature rise with nameplate loading.
Insulation System and Temperature RiseIndustry standards classify insulation systems and rise as shown below:
Table 9-133. Insulation System Classification
The design life of transformers having different insulation systems is the same — the lower temperature systems are designed for the same life as the higher temperature systems.
Sound LevelsAll Cutler-Hammer 600 volt class general purpose dry type distribution transformers are designed to meet NEMA ST-20 levels listed here.
Table 9-134. Sound Levels
1 Applies to general purpose transformers only.
Winding Terminations
Cutler-Hammer recommends external cables be rated 90ºC (sized at 75°C ampacity) for encapsulated designs.
Series-Multiple WindingsSeries-multiple windings consist of 2 similar coils in each winding which can be connected in series or parallel (multiple). Transformers with series-multiple windings are designated with an “X” or “/” between the voltage ratings, such as voltages of “120/240” or “240 X 480.” If the series-multiple winding is designated by an “X,” the winding can be connected only for a series or parallel. With the “/” designa-tion, a mid-point also becomes avail-able in addition to the series or parallel connection. As an example, a 120 X 240 winding can be connected for either 120 (parallel) or 240 (series), but a 120/240 winding can be connected for 120 (parallel), or 240 (series), or 240 with a 120 mid-point.
