TYPE T TRANSFORMERS
The Type T units are designed for the global market and are the best choice
when size and cost are of concern. This is our most popular and complete
offering of industrial control transformers. The following features are
included:
• 50/60 Hz rated
• Customer installed accessories (Finger-Safe covers, fuse blocks, fuse
clips)
• Type T transformers are designed with various temperature classes:
— 25–150 VA with a 55° C temperature rise, 105° C insulation
— 200–350 VA with a 80° C temperature rise, 130° C insulation
— 500–5000 VA with a 115° C temperature rise, 180° C insulation
Schneider Electric manufactures a wide variety of voltage combinations for
control transformers. The voltage combinations are expressed as “Voltage
Codes”, and are embedded within the catalog number of the transformer.
Standard codes are listed. If the voltage combination you need is not listed,
please call your Schneider Electric distributor for assistance.
CE Marking
Industrial control transformers (ICTs) entering the European Union (EU)
after January 1, 1997 are required by EU standards to have CE marking or
Declaration of Conformity to CE. EU documentation requires compliance
with specification EN 61 558 of the Low Voltage Directive. Type T ICTs from
Schneider Electric comply with this specification and are third party tested to
TÜV standards, which adhere to, and are accepted by, EU standards. A
Declaration of Conformity for all Type T units is available upon request.
Because of different overload criteria in the CE specification,
Schneider Elecric dual rates these transformers for UL VA, cUL VA, CSA
VA, NOM VA and CE VA ratings (see “Type T VA Ratings” table). Because
they are widely used with control circuit panels, ICTs are also required to
comply with EN 60 204 and EN 61 558 in these applications. The Type T
transformer line complies with EN 60 204 when Fingersafe
®
covers are
installed.
For more information regarding CE marking, please contact your local
Schneider Electric field sales office.
