Description
Product Description
The GE Multilin SR469-P5-HI-A20 is a microprocessor-based motor protection and management relay designed to monitor and protect medium- and large-sized AC motors. It combines motor protection, operating measurements, fault diagnostics, thermal modeling, and programmable control functions in a draw-out relay assembly for industrial motor control centers and electrical distribution systems.
The relay supports 5 A phase current transformer (CT) inputs, a wide-range control power supply, and four 4–20 mA analog outputs. Protection capabilities include thermal overload, locked rotor, phase imbalance, ground fault, and start supervision, depending on configuration. Communication and system integration should be verified against the installed firmware and application requirements.
