MMP Series
Thermal heat build-up inverse time/inverse time/definite time selection function
It is possible to select one of two types of inverse time and definite time in order to protect a motor perfectly.
Wide setting range and Dual protection
Providing Ground fault protection by dual detections -Zero-phase current and Residual current levels.
Up to 100A the device can be used without external CT to providing convenience and cost-effective solution.
Various Motor Starting Modes
n a Single Device several starting modes of operation available : Full voltage start, Y- △ start, Reversible start,
Reactor start, Inverter start.
Metering of Current, Voltage and Energy (with 1% accuracy for A V)
Real-time energy metering with high accuracy to support energy-saving Current / Voltage THD
Carrying out complex relay functions related to Current, Voltage, Energy and Power Factor
Overpower alarm supported for energy monitoring
Self-diagnosis and Sequence monitoring
Providing a self-diagnosis function such as internal memory check in order to check fault conditions quickly
Power loss and Restarting
Device restarts after the momentary power loss for less than 30 seconds and returns to the former state.
Time-delay setting between 0 to 300 sec. is available to prevent overload from all the motors' restarting
at the same time.
Frequent-Starting Protection
The number of automatic resets for the set time (20 minutes) is settable to provide frequent-starting protection.
