The new REDUR split core current transformer is equipped with a robust and multifunctional polyamide enclosure difficult to inflame (acc. to UL 94 V2) with different fixing possibilities.

Our patented Click-off hinge* can completely be removed which allows to take off the top part of the current transformer completely. This facilitates the mounting even under difficult and tight installation conditions.

Due to our sophisticated spring system a constant contact pressure of the core halves will always be provided. This guarantees long-term stable measuring values.

Mounting feet and snap-on mounting brackets for the installation on DIN rail EN 50022-35 can be supplied optionally.
