UL 2808 Certified Current Transformers

Our Split-Core Current Transformers provide a high accuracy current measurement over a wide dynamic sensing range for power metering applications. Unlike the competition, we offer “Safe CT’s”, which provide a 333 millivolt output directly proportional to the input current. These current transformers are safely and easily installed on existing power lines without disconnecting the lines and interrupting service. The standard 15 foot lead wire also fits the vast majority of all installations, eliminating excess material and time spent extending wire-length during installation.

The CT’s are available from 20A to 400A, all of which are UL2808 Certified. Setra is one of the first in the industry to provide CT’s certified to the UL 2808 standard, now required in many applications.

In addition, pairing these CTs with Setra’s Power Meter provides a complete metering solution to meet your demanding applications.
