Trip Curves
Cold curve: represents the performance of the relay without any previous current flow, first start. Warm curve: the tripping times decrease as the current flows, and are adapted to the motor heating condition based on the thermal memory, the warm condition (IEC-255) is reached after a current of 0.9 x IN (motor rated current) flows during 2 hours approximately.
