Load jam protection

WitrynaLoad jam protection (ANSI 51M) Sudden high loads can cause slowing down and blocking of the motor and mechanical damages. The rise of current due to a load jam is being monitored by this function (alarm and tripping). The overload protection function is too slow and therefore not suitable under these circumstances. Phase-balance current ... WitrynaThermal overload protection (49) Load jam protection (51M) Locked rotor protection (14) Intermittent ground fault protection; Directional intermittent ground fault …
