Product Description

The GE Multilin 469-P5-HI-A20-T is a high-performance motor management relay designed for demanding industrial environments. It delivers comprehensive protection, advanced diagnostics, and real-time monitoring for medium and large motors. Moreover, the relay is widely used in oil and gas, mining, power generation, and heavy manufacturing, where continuous motor availability is essential.

Its protective functions rely on integrated CT, VT, and RTD inputs that track electrical and thermal conditions with high accuracy. In addition, its thermal modeling and ground-fault monitoring help prevent costly motor failures. The relay also supports multiple communication protocols, allowing seamless integration with DCS and PLC systems across diverse facilities. Engineers value its reliability because it combines protection, control, and analytics in one compact enclosure.
