The DPM-20A series microcomputer motor protection device is suitable for the protection and measurement of medium and high voltage asynchronous motors with voltage levels of 35kV and below, and can be directly used

Installed on the switchgear,It can also be installed on a group screen. among whichDPM-20A microcomputer motor protection is used for2000kWThe protection of the following small and medium-sized asynchronous motors;

DPM-21A: No independent measurement CT, measurement data is calculated through protected CT. The current accuracy is level 0.5, and the power accuracy is level 1.0.

DPM-22A: Equipped with independent CT measurement, the measurement data is calculated through CT measurement. The current accuracy is 0.2 level, and the power accuracy is 0.5 level.
