Motor Protection Analyzer

MPA2 is a micro-controlled based three-phase Motor Protec-

tion Analyzer Relay specifically designed to protect electric

loads and motors from failure and damage due to common

current and voltage faults.

MPA2 constantly supervises current and voltage values.

When any harmful condition occurs, the output connection is

deactivated until the fault disappears, power line conditions

return to an acceptable level and the motor has been totally

cooled. Specific timing such as Start Up Delay (TC) and Trip

Delay (TD) are incorporated to prevent nuisance tripping

due to rapid power fluctuations.

MPA2 provides LCD Display to indicate the output status

voltage, current, unbalance, frequency and load status and

failure conditions. It also provides four (4) push buttons (1

for START, 2 for ADJUST and 1 for SELECT) for operation and

protection parameters adjustment. Besides these mentioned

advantages, a Communication Port with MODBUS RTU proto-

col is included with MPA2.

An innovative mechanical design allows two (2) placement

options:

• Symmetrical Din-Rail mounting.

• Flat Surface mounting, using an exclusive attachable

mounting ear.

MPA2 has been developed using the most advanced technol-

ogy and designed in accordance with the IEEE, IEC and

NEMA protection standards and developed in compliance

with IEC electromagnetic compatibility standards, working

safely under the hardest electrical environments.

When you use a MPA2 Motor Protection Analyzer, you are

working with the best solution to protect your most impor-

tant investments.
