LINETRAXX® CTAS seriesDivisible measuring current transformer Hr BENDER CTAS120

Divisible measuring current transformers Device features Product description The divisible measuring current transformers of the CTAS series allow the measuring current transformer to be opened by means of a locking button and place them around the conductors to be monitored. This enables easy retrofitting in existing systems. The divisible, highly sensitive CTAS series measuring current transformers in combination with RCM or RCMS series residual current monitors and evaluators convert AC currents into an evaluable measurement signal. They are also suitable for use in insulation fault location...
