Overview:
General Electric IAC-series relays are induction-disc electromechanical protective relays long used in utility and industrial switchgear for overcurrent, ground-fault, and voltage protection. Although newer installations use microprocessor relays, a large installed base of IAC relays remains in service, and utilities, plants, and switchgear shops actively source used IAC units to maintain, repair, and extend legacy protection schemes where exact-match replacements are needed. This lot offers 103 relays across the common 50/51, 50/51G, and 47/27 functions in a single purchase, making it well suited to a buyer maintaining an existing fleet, a relay refurbisher, or a panel shop building repair stock. The two broken-window 47/27 units remain useful for parts or repair. Buyers should budget for testing and calibration.
