Multilin 369-HI-0-0-0-0-0-E | GE Fanuc | Motor Management Relay

Description

The Multilin 369-HI-0-0-0-0-0-E is a GE Fanuc motor management relay designed to protect and monitor three-phase motors and their associated systems. It operates on a flexible control power range of 50-300 VDC / 40-265 VAC, making it compatible with diverse industrial power setups. Equipped with 12 optional RTD inputs, it supports temperature monitoring from sources like bearings, stators, and environmental sensors to detect overheating and prevent motor damage. This model does not include metering or anti-spin detection features, and has no optional fiber optic ports. A key adaptive feature is its ability to “learn” individual motor parameters, allowing users to adjust surge current, cooling rate, and acceleration time to match specific application requirements. Its comprehensive protection suite includes over 30 functions, such as under-voltage auto-restart, reverse power detection, starter fault monitoring, kVA/kvar/kW demand tracking, reverse rotation detection, self-test/service diagnostics, trip counters, open/damaged RTD alerts, mechanical jam protection, over/under frequency protection, over/under voltage protection, power factor monitoring, overload protection, ground fault and ground fault backup, short circuit backup, current imbalance protection, and undercurrent/underpower protection, ensuring robust, multi-layered defense for critical motor systems.
