About the 239

Motor Protection Relay 239 was designed by General Electric to fully protect three-phase AC motors against damaging conditions. This model can protect motors and does also have options to protect the mechanical equipment the unit is being used with. If a potential process malfunction has occurred this model does have the capability to sound off an alarm prior to any damage occurring. 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.

One major upside of the 239 Relay is that the aerodynamic and compact design will help lower and assist with the installation costs. 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. 

For simple easy testing, the 239 comes with built-in simulation features. This unit has temperature asset monitoring and a separate flash memory which allows for product field upgrades. There are two primary ground faults used with this device- alarm, and trip. The 239  has thermal overload with fifteen selectable curves with features such as immediate current and overload alarm. This device also has 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.
