15.1.2 Functionality
M12275-3 v10
A function block for protection tripping is always provided as basic for each circuit breaker
involved in the tripping of the fault. It provides a settable pulse prolongation to ensure a trip pulse
of sufficient length, as well as all functionality necessary for correct co-operation with
autoreclosing functions.
The trip function block also includes a settable latch functionality for evolving faults and breaker
lock-out.
