PRODUCT DESCRIPTION
Control power transformers from Schneider Electric set the industry standard for design innovation and
performance. They are designed with low impedance windings for excellent voltage regulation, and
can accomodate the high inrush current associated with contactors, starters, solenoids, and relays.
A variety of designs are available to meet the diverse needs of panel builders and machinery OEMs.
The versatility of our control transformer line offers unparalleled options for design engineers. We also
have one of the most extensive offering of custom products with no minimum order requirements.
We have a national network of distributors to ensure prompt delivery, including industry leading
delivery on custom products. In most cases, we can design, manufacture, and ship a custom unit in
two weeks or less.
The Global Product Offering—Type T
Type T is our most popular and complete line of control transformers. It comes with unmatched design
innovations for top performance and is manufactured using the most advanced insulating materials.
The Type T control transformer is the best choice if size and cost are of concern.
The Exceptional Regulation Offering —Type EO
Constructed with traditional materials and manufacturing processes, Type EO transformers are UL and
CSA Component Recognized. Units are designed for 55°C rise. All units are 60HZ rated, with
de-rated VA levels for 50HZ.
Transformers with Fuse Block Protection—Types TF and EOF
We offer both product lines with factory installed overcurrent protection fuse blocks.
Type TF and EOF transformers consist of two primary fuse blocks and one secondary fuse block, a
configuration that meets the majority of overcurrent needs by panel builders and machinery OEMs.
Since the fuse blocks are pre-wired and mounted on top of the transformer, the Type TF and EOF
transformers have the same footprint as the Type T and Type EO units, respectively. This design frees
up space normally used for separate fuse blocks
We also have an extensive fuse block offering for custom applications. See the overcurrent section of
this catalog for full details.
Leaded Control Transformer Line
Schneider Electric offers transformers with internally pre-wired 24-inch primary and secondary leads,
instead of terminal boards, to make installation easier and faster for many applications. These are only
available for single voltage primary and single voltage secondary applications.
MultiTap
Schneider Electric offers Type T and Type EO transformers in the MultiTap version. The MultiTap
control transformer was designed to respond to the increased need for voltage and stock flexibility. It
combines multiple primary voltages with one or more secondary voltages, all in a single transfomer.
The most flexible MultiTap voltage is the Universal, available on the Type T product line only. It allows
for standard primary voltages of 208 to 600V and 110, 115, or 120V secondary voltages.
