About the 369-HI-R-M-0-0

Equipped with an optional metering feature and twelve RTD inputs, this model of General Electric Multilin’s 369 Motor Protection series safeguards and controls motors and accompanying motor equipment of medium size. The 369-HI-R-M-0-0 employs technology like ground overcurrent protection and start inhibiting to protect motors and extend system life. Users are able to use this unit’s metering capabilities to track quantities like voltage, watts, power factor, frequency, and energy. Users can then create setpoints to enable protective functions related to these parameters, adding to the versatility of the system.

The relay runs on highly configurable setpoints that guide the protective functions of the system and generally establish system functions. The Multilin 369-HI-R-M-0-0 features the 369 Motor Settings Auto-Configurator, making setpoint creation easier than ever. Users can further modify these setpoints after auto-configuration, further specifying and refining setting files. Setpoints can be created, edited, or deleted through the relay’s 40-character LCD and keypad, or more efficiently modified through the EnerVista 369 software program. Computers running EnerVista 369 can connect to the relay through the RS232 port, and the software program offers a better display for system metrics and a generally improved User Interface.

This 369-HI-R-M-0-0’s optional twelve Resistance Temperature Detectors (RTD) are able to assess actual temperatures within the system. In this unit, each RTD’s three wires are composed of 100 Ω platinum, 100 Ω nickel, 120 Ω nickel,10 Ω copper. As temperature shifts in the system, RTDs generate a resistance value that can be reliably measured and converted to Fahrenheit.
