Woodward 8440-2150 LS-5 V2 Circuit Breaker Controller

Product Overview

The Woodward 8440-2150 LS-5 V2 Circuit Breaker Controller is engineered for precise synchronization and dependable breaker protection in demanding power systems.
It supports safe generator and grid interconnection while maintaining stable load sharing across multiple bus segments.
Moreover, the controller combines advanced protection logic with intuitive operation for engineers managing complex electrical networks.
Therefore, it is widely trusted in industrial and utility environments requiring continuous availability and controlled power flow.

Functional Highlights

The controller delivers accurate synchronization, ensuring breakers close only under safe voltage, frequency, and phase conditions.
In addition, integrated mains decoupling protects generators and loads during abnormal grid events or islanding situations.
Moreover, flexible operating modes allow automatic, manual, or stand-alone control depending on system requirements.
For instance, bus segment synchronization enables secure coupling or separation of multiple generator groups.
Therefore, operators gain improved system stability, reduced blackout risk, and predictable power management performance.
