Transformers on El and Ul core

Isolation transformers

Network transformers with transformation ratio 1:1. They are used to protect against electrical shock by touching a live part, i.e. as a safety element, for example on production lines, in workshops, in laboratories, etc.

Type range: TR 9409/4 to TR 9415/4

We also produce atypical transformation ratios according to the customer's request.

Our recommendations

  • protection by "T" tube fuses as indicated on the manufacturer's label
  • based on the customer's request, we can install a thermal fuse for 130 °C - returnable and non-returnable
  • technical changes and transformation ratios are possible based on customer requirements
