220.127.116.11.1 Semantic definition
Tripping curves are applied to thermal, thermal magnetic or MCB_RCD tripping units (i.e. tripping units having type property sets for thermal, thermal magnetic or MCB_RCD tripping defined). They are not applied to electronic tripping units.

The type of tripping curve that is represented by the property set.
A curve that establishes the release time of a tripping unit when a particular prospective current is applied. Note that the tripping curve is defined within a Cartesian coordinate system and this fact must be asserted within the property set:
(1) Defining value is the Prospective Current which is a list of minimum 2 and maximum 16 numbers providing the currents in [x In] for points in the current/time log/log coordinate space. The curve is drawn as a straight line between two consecutive points. (2) Defined value is a list of minimum 2 and maximum 16 numbers providing the release_time in [s] for points in the current/time log/log coordinate space. The curve is drawn as a straight line between two consecutive points. Note that a defined interpolation.
