Product Description

Shunt Test Unit -STU for VD4 EL

STU Shunt Test Unit

Due to the particular construction of these releases, checking the functionality of the shunt closing (-MC) and opening (-MO1, -MO2) releases is not possible with dedicated relays (e.g. TCS Test Control Supervision, CCC Control Coil Continuity) or with the REF control and protection unit. The only device able to carry out a check of the functionality is the STU device. Please contact us if you want to carry out this control with devices other than STU.

This device can be combined with the shunt opening release (-MO1; -MO2) or with the shunt closing release (-MC) to check functionality and continuity.

The control/monitoring Shunt Test Unit allows the continuity of releases with a rated operating voltage between 24 V and 250 V (AC and DC) to be checked, as well as the functionality of the electronic circuit of the release.

Checking continuity is carried out cyclically with an interval of 20 seconds between one test and the next.
