Measuring current transformers of the WS50x80S…WS80x160S series, split-core type Product description The highly sensitive split-core-type WS… series measuring current transformers convert residual currents of 10 mA…100 A into evaluable RCM or EDS signals and can be retrofitted to existing electrical installations where disconnection must be prevented. The CTs are connected to the respective evaluator by two wires. Depending on the connecting lead used, the distance between the CT and the evaluator may be up to 40 m. Make sure that all live conductors are routed through the measuring current...

Installation instructions • Do not pass shielded cables through the measuring current transformer. • s a general principle, the PE conductor and low-resistance conductor loops must not be passed through the measuring current transformer! A It is important that the leads are passed through the measuring current transformer in the right direction The primary conductors may only be bent from the specified minimum distance. The minimum bending radius specified by the manufacturers must be observed. * Distance to 90° angle: 2x transformer The leads must be aligned with the centre of the...
