The DMPR230S000 from MTE is an electronic motor protection relay. This relay together with suitable current transformer monitors motor supply current. Three phase motors generally requires two current transformers. An overload condition causes the unit to trip after a time delay inversely proportional to overcurrent. The protection relay provides independently adjustable time delays for starting and normal running. This allows an extended response time during starting while maintaining a fast response during normal running. By setting the run delay time at minimum (0.2s), shear pin type protection is achieved.
