    Woodward’s LS-4 is a breaker control and protection module used to expand the number of controlled breakers in a power generation and distribution system. The LS-4 is applied when you need to control, synchronize, and protect multiple main feeders or bus tie breakers.

    An automatic adjustment in frequency, voltage, and load is handled by the LS-4 and the connected GCP-30 genset controls. You are able to operate up to 14 GCP genset controllers and 8 LS-4 circuit breaker controllers in one networked application.

    Features include:

    • True RMS current and voltage sensing
    • Synch-check and synchronization features
    • Dead bus start functionality
    • Soft loading and Unloading sequencing
    • Breaker Monitoring features
    • Mains Decoupling features
