The MP 204 monitors the following parameters
• System insulation resistance to earth before start
• Motor temperature. Only possible if the motor is fitted with an operational Tempcon temperature transmitter, a
Pt100/
Pt1000 or a PTC sensor
• Current consumption and unbalance, supply voltage, phase sequence, missing phase, power factor (cos phi),
harmonic distortion, starting capacitor (single-phase operation only), run capacitor (single-phase operation only)
The MP 204 protects against
• Overload, dry running in pumping systems, incipient motor defect, too high motor temperature, supply failure
Rated voltage 1/3 x 100-480V
Current range 3-120A
For higher current, MP204 must be fitted with a CT current transformer
