Product Overview
The 369-HI-R-M-F-P1-0-E (ordering code 369HIRMFP10E) is an authoritative Motor Protection Relay from the GE Multilin 369 series. This module is a mechanical necessity for monitoring and protecting medium to large horsepower motors against electrical and mechanical stress. By integrating sophisticated thermal modeling, current sensing, and communication logic into a ruggedized chassis, the 369-HI-R-M-F-P1-0-E ensures deterministic motor operation. It serves as a primary protective barrier, preventing insulation breakdown and mechanical damage due to overloads, ground faults, or phase imbalances in critical industrial sectors like mining, oil and gas, and water treatment.

Engineering and Operational Guidelines
-
Thermal Management Expertise: The 369-HI-R-M-F-P1-0-E utilizes a proprietary thermal algorithm that factors in RTD feedback and current statistics. This expertise allows for maximum motor utilization by calculating the true thermal capacity used, which is essential for protecting against repeated hot starts.
-
Redundant Communication Logic: Featuring the "R" option, this relay provides dual RS485 ports. This trustworthy design ensures that if one communication channel fails, the SCADA system maintains real-time visibility of motor health, preventing unmonitored operation.
-
Authoritative Protection Suite: The unit includes integrated protection for locked rotor, phase reversal, and ground faults. The "P1" 1A input group is optimized for high-sensitivity detection, allowing for rapid fault isolation before localized heat causes permanent stator damage.
-
Harsh Environment Resilience: The "E" designation confirms that the internal circuit boards are conformal coated. This is an engineering requirement for installations in corrosive environments, such as chemical plants or wastewater facilities, where airborne contaminants could lead to logic board degradation.
Technical FAQ
Q: What are the primary differences between the 369 and the 750 series?
A: The 369-HI-R-M-F-P1-0-E is specifically a "Motor Management" system designed for compact integration on motor control centers (MCC). The 750 series is a more comprehensive "Motor Protection" system typically used for larger, more complex utility-scale motors requiring higher I/O counts.
Q: Can this relay be used with 5A CT secondaries?
A: This specific configuration (P1) is designed for 1A Phase CT secondaries. Using it with 5A CTs will result in incorrect metering and protection trips. Professional best practice dictates matching the relay hardware to the CT ratio on-site.
Q: How does the Fiber Optic (F) port improve system reliability?
A: The fiber optic port provides total electrical isolation for communication signals. In environments with high electromagnetic interference (EMI), such as near large variable frequency drives (VFDs), this port ensures that data packets are not corrupted.
