DIRIS A-40<br />

Multi-functions meters<br />

Connections<br />

Associated current sensors<br />

Various types of current sensors can be connected to the DIRIS A-40: solid-core (TE), split-core (TR/iTR) or Rogowski (TF). This range of sensors is suitable for all<br />

types of new or existing installations. A quick RJ12 connection makes wiring easy and reliable and prevents wiring errors. The DIRIS A-40 automatically recognizes<br />

the sensor type and rating. This guarantees the overall accuracy of the DIRIS A-40 + current sensor measurement chain.<br />
