GE General Electric 12CEH51A1A | CEH 51A1A Loss of Excitation Relay 115V 5A 60Hz

GE General Electric 12CEH51A1A | CEH 51A1A Loss of Excitation Relay 115V 5A 60Hz NSMP Model Number: 12CEH51A1A Type Code Designation: Type CEH Primary Signal Loop: 115 Volts AC | 5 Amps | 60 Cycles (Hz) Auxiliary Control Voltage Range: 125–250 VDC Condition Class: NSMP – New Surplus Manufacturer Package (OEM) Product Overview Up for sale is a brand-new, unused General Electric (Model: 12CEH51A1A) Type CEH loss-of-excitation power utility protection relay module. This industrial switchgear asset is engineered to continuously monitor the magnetic field excitation of large synchronous generators and motors. Operating within a 115V AC / 5A measurement loop, the relay automatically detects abnormal field drops or partial short-circuit losses, triggering disconnect safety breakers via its 125–250V DC auxiliary control network loop to safeguard heavy power infrastructure from overheating and slip-out-of-synchronism structural stress. Highly sought after for retrofitting legacy electrical substations, hydro/thermal turbine installations, and industrial switchgear lines. Manufactured in Malvern, Pennsylvania, USA.
