5.3.4 Continuous breaker
CAUTION
Due to class requirements, this breaker type is not suitable for marine use. This is because, if the controller failed, then the
breaker would open and the ship would lose power.
You can configure a continuous breaker to use a open breaker signal, an close breaker signal, or an open and a close breaker
signal to open and close the breaker. Configuring both an open and a close breaker signal for a continuous breaker ensures that
synchronisation is precise and that AC protections meet the required operation times.
