Thermal memory This function is used to protect components such as transformers and cables against overheat- ing due to overloads. It adjusts the trip time of the protection according to the time elapsed after the first overload, taking account of the overheating caused. It can be activated when a t = k/l 2 (with an inverse long time) curve is used.

Trip Enable The function enables the trip to be excluded so that only the alarm is indicated. This is used in installa- tions where continuity of service is an essential re- quirement.
