MP380
MP380
A rule of thumb in industry to measure the decrease in motor life expectancy is that for each 10 degrees centigrade of operating temperature increase, the life expectancy of the motor insulation decreases by 50%. A fairly comprehensive, microprocessor-based solution to protect expensive motors is offered by E-Labs. MP380 provides the much needed monitoring of the supply before starting the motor and while it is running.
