Functionality
A function block for protection tripping is provided for each circuit breaker involved in
the tripping of the fault. It provides the settable pulse prolongation to ensure an one- or
three-phase trip pulse of sufficient length, as well as all functionality necessary for correct
cooperation with autoreclosing and communication logic functions.
The trip function block includes functionality for evolving faults and a settable latch for
breaker lock-out.
