Residual current sensor for retrofit installation in split-core-design with correction factors


The ExxxE-xx current sensor is dedicated for installation on the cables of a gas or air 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. Due to cost effective construction, the sensor has a very high cost-benefit ratio.


  • Passive technology – no active parts are inside, nor power supply is needed
  • Splitable form factor for retrofit installations
  • Easy installation on bushings and cables
  • Big inner diameter for installation on 3 cables
  • Correction factors for amplitude and phase inaccuracy improve the sensor class
