Transformadores actuales con salida de relé XAC ... / XAT

New CT with programmable output range.
This innovative product permits to set an overcurrent threshold on the some CT withou interposing any measuring relays and without any auxiliary supply source.
The electronic board is fitted inside the CT frame. Two miniature trimmers are available to set the threshold value and the alarm intervention delay.
These new CTs characteristics allow to get a cost reduction and a very simple wiring.

Current transformers with relay output XAC… / XAT… are modern devices that, thanks to a split core or openable core and a built-in sensor, allow accurate current measurement in AC and DC installations, both in three-phase and single-phase systems. The primary and secondary windings work with measuring equipment and automation systems, providing current monitoring in conductors, DIN rails, and other electrical installation elements.

Thanks to high accuracy, class 1, and a wide range of current values (from 5A to 200A), these transformers enable precise secondary current measurement, easy connection via terminals, and integration with monitoring and automation systems. The offer includes models providing reliable measurement in both industrial and energy applications, ensuring safety and operational stability in any installation.
