This value is indicated in the following diagrams as a function of the progressive system short-circuit current. Protected Min. The maximum possible tripping current is substantially lower than in fused overload protection. Short-circuit protection is provided by the non-adjustable magnetic release which is capable of opening the main contacts very quickly.

The short total breaking time limits temperature rise in the lead to a minimum in the event of a short-circuit. ForwardEnergyidt[10As] In equipment at operating temperature, release time is less than or equal to release time from the cold state. The precise routine test guarantees motor protection even when a phase is interrupted. Such protection equipment must ensure motor protection even in the event of a phase failure.

In motors with a rated output greater than 3 kW, additional protection devices must be provided which ensure motor protection even in the event of a phase failure. At the upper thermal release setting, this tripping current is 11 times MN or 14 times CMN the set current; at a lower setting it is correspondingly higher.
