Tripping logic common 3-phase output
Functionality
A function block for protection tripping is provided for each circuit breaker involved
in the tripping of the fault. It provides a settable pulse prolongation to ensure a three-
phase 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 breaker lock-
