The pulse length should be long enough to securethe breaker opening.For three-pole tripping logic common 3-phase output, SMPPTRC (94) has a single input(TRINP_3P) through which all trip output signals from the protection functions within theIED, or from external protection functions via one or more of the IEDs binary inputs, areSection 13 1MRK 506 335-UUS ALogic530Technical manual
