AC/DC sensitive measuring current transformer (Type B)

Device features • Multicolour LED for operation, fault and status messages • Electronic module can be exchanged without mechanical separation of the primary conductors • Monitoring of the connection to the measuring current transformer AC/DC sensitive measuring current transformer (Type B)Product description The AC/DC sensitive measuring current transformers of the CTUB103 series convert system leakage and fault currents into an evaluable measurement signal. The devices are suitable for detecting fault currents with smooth DC components. They consist of a CTBC... measuring current transformer...

Installation instructions • Do not route any shielded cables through the measuring current transformer. * Distance to 90° angle: 2x external diameter of the current transformer The primary conductors may only be bent from the specified minimum distance. The minimum bending radius specified by the manufacturers for the conductors used must be observed. The cables must be aligned with the centre of the measuring current transformer. Bender GmbH & Co.
