WS… and WS…-8000 series split-core type measuring current transformers can be opened using the interlock knob to enclose the conductors to be monitored. That allows easy retrofitting in existing installations.

WS… und WS…-8000 series measuring current transformers are highly sensitive measuring current transformers of split-core type which in combination with RCM series residual current monitors and RCMS residual current monitoring systems convert AC currents into evaluable measurement signals.

In addition, the measuring current transformers can be used in combination with insulation fault locators (EDS) for IT systems. They are designed to measure the test current generated by a PGH locating current injector or an ISOMETER® IRDH. In combination with EDS series insulation fault locators the test current is converted into evaluable signals.

Connection to the respective devices is via a two-wire cable.
