14 Tripping Characteristic Curves
The tripping characteristic curves refer to a 3-pole load from cold state at an ambient
temperature of + 20 °C and any position.
The deviation of the tripping time (from a current three times higher than the rated current)
is max. 20 % according to EN 60079-14.
The following tripping characteristic curves show the tripping time depending on the
current ratio l

.
Legend:
1) Multiples of the rated current
2) Tripping time
3) 2-pole
4) 3-pole
5) Electromagnetic release
