Product catalog summary

Product Description
The W0-S20…W5-S210 series measuring current transformers are designed to convert residual currents up to 100 A into RCM or EDS signals. They connect to evaluators via two wires, with a maximum distance of 40 m depending on the connecting lead. It is crucial that all current-carrying conductors pass through the CT without shielding, and PE conductors should never be routed through the transformer.

Typical Applications

Residual current monitors (RCM)
Residual current monitoring systems (RCMS)
Insulation fault locators with additional EDS in AC and DC systems

Standards and Approvals
The transformers comply with IEC 61869-1 standards. Various models have different approvals, such as UL and EAC.

Technical Data

Insulation coordination: IEC 60044-1
Highest system voltage: AC 720 V
Rated transformation ratio: 600/1
Rated burden: 180 Ω
Accuracy class: 3
Operating temperature: -10 to +50 °C
Degree of protection: IP40 (internal), IP20 (terminals)

Installation Instructions

Do not pass shielded cables through the transformer.
Ensure all current-carrying leads pass through the transformer in the correct direction.
Maintain specified minimum bending radius for primary conductors.

Dimensions and Weight
Various models have different dimensions and weights, ranging from 85 g for W10/600 to 2500 g for W5-S210.

Connection Details

Connection via screw-type terminals.
Conductor sizes range from 0.2 to 4 mm².
Recommended shielded cable: J-Y(St)Y min. 2 x 0.6.

Environmental and Mechanical Specifications

Shock resistance: 15 g/11 ms
Vibration resistance: 1 g/10…150 Hz
Climatic class: 3K22

Measuring current transformers Product description The highly sensitive W0-S20...W5-S210 series measuring current transformers convert residual currents up to 100 A into evaluable RCM or EDS signals. 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. Care should be taken that all current-carrying conductors are passed through the CT and that these conductors are not shielded. Never route a PE conductor through the measuring current transformer!
