Product Description P/N: 12IAV51A1A
Description
The General Electric 12IAV51A1A is a heavy-duty single-phase power directional time-delay relay from the GE Multilin IAV series, designed for protective relaying in high-voltage transmission and distribution systems. Operating at 115 VAC,60 Hz, this electromechanical protective unit monitors power flow direction and voltage levels to execute selective tripping during ground faults, reverse power conditions, or abnormal system phase-angle shifts.

Information About 12IAV51A1A
The 12IAV51A1A protective relay belongs to General Electric's time-tested IAV family of induction-disk voltage and directional relays. Weighing 5.75 kgs, it features a drawout case design that simplifies routine maintenance, testing, and calibration without disturbing permanent panel wiring. Built with precision electromagnetic induction elements and adjustable time-dial settings, it delivers predictable inverse-time operating characteristics to safeguard transformers,generators, and distribution feeders from system disturbances.
Key Features:
-
Reliable 115 VAC 60 Hz Operation: Engineered for standard secondary voltage inputs from substation voltage transformers (VTs).
-
Induction-Disk Directional Sensing: Precision electromechanical mechanism provides dependable directional power detection.
-
Protective Relay Coordination: Features adjustable time-dial calibration to ensure proper trip coordination with downstream protection.
-
Drawout Case Design: Allows quick unit withdrawal for inspection, testing, or replacement without disconnecting panel cables.
-
Robust 5.75 kgs Construction: Heavy-duty metal chassis built to withstand demanding utility substation thermal and mechanical stress.
-
Dual System Protection: Effective for both reverse power monitoring and directional ground-fault protective schemes.
-
High Dielectric Isolation: Superior internal coil insulation protects sensitive control loops against high-voltage surges.
-
Clear Target Indication: Integrated visual targets provide immediate flag indication following a relay trip event.
The 12IAV51A1A power directional relay delivers the mechanical precision, voltage endurance, and trip accuracy required for mission-critical utility power protection.
