Split-core current transformers are often used in retrofit applications. These transformers have an open core ready for installation. Fitted around the busbars, installation can proceed without interrupting the primary conductor.
Cable-type split-core current transformers are exclusively suited for installation in isolated primary circuit conductors (supply cables) in weatherproof and dry locations. Installation can be done without interrupting the primary conductor (i.e., while operation is ongoing).
The DIN rail current transformer is a unique, highly-compact variant with integrated voltage tap. It includes a terminal strip, current transformer and the voltage tap terminal with fuse. The fuse is fitted directly on the primary conductor. Therefore, the unprotected part of the measurement line is very short, ensuring a high degree of intrinsic safety.
The DIN rail current transformer is simple to wire, resulting in low installation costs, and offers high reliability due to fewer connections. It is also space-efficient and exhibits very few connection faults.
