LINETRAXX® WF… series

Product catalog summary

Overview
The LINETRAXX® WF series consists of flexible measuring current transformers (WF170, WF250, WF500, WF800, WF1200, WF1800) and an RCC420 signal converter. These components are designed for residual current monitoring systems, specifically the RCMS460/490 and RCM420-D9 series.

Device Features

Flexible measuring current transformers available in various lengths.
Space-saving design with easy installation and retrofitting capabilities.
Installation without disconnecting conductors.
Connection monitoring for WF series transformers.
Analogue output for external measuring devices.
Push-wire terminals on RCC420 for easy connections.

Product Description
The WF series transformers are sensitive devices that measure AC currents and convert them into evaluable signals for residual current monitoring systems. They connect to monitors via a two-wire cable.

Applications

Monitoring residual, fault, and nominal currents in non-switchable loads and systems.
EMC monitoring of TN-S systems for stray currents.
Ensuring PE and equipotential bonding conductors are current-free.

Installation Instructions

Pass all live conductors through the transformer.
Ensure conductors pass centrally and at right angles through the opening.
Avoid placing transformers near strong magnetic fields.

Technical Specifications

Electrical safety standards: RCC420 IEC 61010-2-030, WF series IEC 61010-1 and IEC 61010-2-032 CAT III.
