About the 239

239 Multilin Motor Management Relay Device Functionality

Motor Protection Relay 239 was designed by General Electric to fully protect three-phase AC motors against damaging conditions. This model can:

• protect motors
• protect the mechanical equipment the unit is being used with (optional) 
• sound off an alarm prior to any damage occurring; if a potential process malfunction has occurred .
• help lower and assist with various installation costs through an aerodynamic design

If enhanced protection of any kind is needed this model will incorporate other thermal models to help with the protection feature. Due to a collective group of setpoints, the 239 model allows for settings on this model to be more flexible. If diagnostic issues occur during the operation of this model verification is needed so the relay’s operation can be corrected during the routine maintenance of the motor.

239 Multilin Motor Management Relay Hardware Specs

For simple easy testing, the 239 comes with built-in simulation features. This unit has:

• temperature asset monitoring
• a separate flash memory
•  two primary ground faults
  • alarm
  • trip
• thermal overload with fifteen selectable curves
• an option of single-phasing and current unbalance

The 239 has multi-speed motor protection as well as motor start supervision. This unit is equipped with a display that can focus on temperature, current, and status. There is a trip record on this device that has the ability to save up to the last five events.
