Product Description■ Epoxy-encapsulated coils

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 Listed■ CSA certified ■ Epoxy encapsulated (MTG is Open

Core-Coil)■ Laminations of high quality silicon

steel to minimize core losses and optimize performance

■ Copper magnet wire for high quality, efficient operation

■ Secondary fuse clips where applicable

■ Optional primary fusing■ Molded in terminals■ 50/60 Hz operation■ 55°C rise, 105ºC insulation system■ Performance meets/exceeds

requirements of ANSI/NEMA ST-1■ Regulation exceeds ANSI/NEMA

requirements for all ratings■ 25 – 1500 VA ratings■ Molded-in terminals for maximum

durability

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. All 600 volt class transformers are UL listed unless otherwise noted.

Options and AccessoriesPrimary Fuse KitThe primary fuse kit includes a 2-pole class CC fuse block, instructions, and all associated mounting and wiring hardware. Fuses are not included. When installed, the primary fuse kit will add a maximum of 11/16 inch to the transformer depth and 1-15/16 inches to the transformer height.
