90% of total burn out of the motors is mainly caused by unbalanced voltage conditions or phase failure. This fault needs to be detected and trip the motor if it goes beyond the set levels.

Bee Bee Phase Loss Relay is a Micro controller based intelligent circuitry that senses each pulses of voltage sequence of all the three phases continuously and if it detects a change or when it crosses the desire limits, it trips the Starter with time delay and protects the motor from burnout.
