ABSTRACT:
Solid state circuitry designed to protect three phase electrical equipment operating from two hundred forty (240) to four hundred eighty (480) volt power from loss of any phase, phase reversal, or under voltage or over voltage of the power supply. The circuitry is designed so that if phasing and voltage are correct, then the device will energize an output relay thus enabling the load to operate the protected equipment. This circuitry accomplishes all of the above with much lower power dissipation than other monitoring devices.
