WL Circuit Breaker

Introduction and Overview

The demands regarding communications capability, data transparency, flexibility and integration in power distribution systems are increasing all the time. The WL Circuit Breaker is a modular circuit breaker that fulfills the requirements of the future today.

Brief Description of the WL Circuit Breaker

Circuit breakers today are no longer simply devices for protecting plants, transformers, generators and motors. Many users now require a complete overview of the plant from a central control room and round-the-clock access to all available information. Modern power distribution systems are characterized by the methods used to network circuit breakers— both with each other and other components. The circuit breakers in the

WL Circuit Breaker family have a lot to offer:

It is possible to carry out analysis and maintenance procedures remotely via the Internet. Operating staff can be given immediate access to information on system status and alarms. This is not just a vision of the future, but reality.

The WL Circuit Breaker covers the entire range from 200A to 5000A. The devices are available with different interrupting ratings, allowing short- circuit currents of up to

200kA to be interrupted reliably.

WL Circuit Breakers can be adapted to different system conditions, which means that a rating plug can be used to adapt each circuit breaker to the appropriate rated current. This ensures that optimum protection is provided, even if changes have been made in the system. The modules (reference Graphic 2-1) can be replaced without the need for the transformer to be changed.

Note: Installation instructions related to the communication modules described in this section can be found in the individual instruction sheets and/or Section 9 of the Operator's Manual
