Frequently Asked Questions about 239-RTD
How does the 239-RTD Multilin relay protect from damage to motors?
The GE Multilin 239-RTD actually sounds an alarm prior to damage from a process malfunction. It can also diagnose and verify correct function.
Does it matter what voltage is for the motor being protected by the 239-RTD?
No, the voltage does not matter. The 239-RTD system will protect a motor regardless of the specific voltage.
How many relays are needed?
One 239-RTD relay is needed for each motor, even though motors can be guarded no matter which voltage they are.
What differentiates the 239-RTD from the 239-RTD-AN and from the 239-RTD-AN-H?
The GE multilin 239-RTD is different from the 239-RTD-AN and from the 239-RTD-AN-H in terms of its composition. The 239-RTD is made to protect three motors, and has a programmable feature. It is also composed of copper, nickel, and platinum.
