The MP 204 is an electronic motor protector, designed for the protection of an asynchronous motor or a pump.

The motor protector consists of:

  • A cabinet incorporating instrument transformers and electronics
  • A control panel with operating buttons and display for reading data.


The MP 204 operates with two sets of limits:

  • A set of warning limits
  • A set of trip limits.


The MP 204 motor protection unit was developed to bring you pump protection that is as simple to use as it is efficient. Pump specialists crammed it full of all the protection features you need – but kept it easy to install, set up, and use.

The MP 204 monitors the following parameters:

  • Insulation resistance before start-up
  • Temperature (Tempcon, Pt sensor and PTC/thermal switch)
  • Overload/underload
  • Overvoltage/undervoltage
  • Phase sequence
  • Phase missing
  • Power factor
  • Power consumption
  • Harmonic distortion
  • Run and start capacitor (single-phase)
  • Operating hours and number of starts.
