ExxxT-0x

Product description

The ExxxT-xx current sensor is dedicated for installation on the cables of a gas or insulated switchgear in the primary or secondary energy distribution. The design is splitable, which makes it easy to put the sensor on an existing cable. Earthing could be done at the current sensor, or through the shielding of the cable or through the S2 connection inside the IED.
