About the 239-RTD-AN-H

GE Multilin 239-RTD-AN-H Relay Features:
  • The 239-RTD-AN-H Relay distinguishes itself from other relays in the series by possessing a harsh environmental conformal coating, in addition to being an analog resistance temperature detector (RTD).
  • As an analog unit, it provides an analog output compatible with automated equipment, programmable controllers, and chart recorders.
  • The 239-RTD-AN-H supports continuous monitoring of parameters such as:
    • Average Phase AMPS
    • Motor Load
    • Thermal Capacity
  • Each phase has a corresponding percentage of full load.
  • Temperature options under RTD1, RTD2, or RTD3 are also required.
  • All associated values for the 239-RTD-AN-H relay can be accessed digitally via its communication interface.
  • It is crucial to know the connected motor load when using the 239-RTD-AN-H to prevent unnecessary relay tripping.
  • The analog output can be used with a remote meter (sold separately), which can be calibrated from 0% to 100% of the motor's capacity.
  • This remote meter, ideally placed near the operator and connected to the relay, indicates the amount of memory charged, corresponding to the motor's heat buildup.
  • If the meter approaches 100% capacity during operation, it signals that the relay is close to tripping.
  • The meter features a lockout time and displays the remaining charge in memory, indicating the potential duration of the lockout.

Frequently Asked Questions about 239-RTD-AN-H

What differentiates the GE Multilin 239 motor protection relay from the motor protection relay with the 239-RTD-AN-H options for the order code?
The difference in the 239-RTD-AN-H order code from the parent motor protection relay is that the H order code signifies the additional featrue of the harsh environment conformal coating. 
What are the analog options for the GE Multilin 239-RTD-AN-H?
The analog options for the GE Multilin motor protection relay with part number 239-RTD-AN-H come in three options: 0-1 mA, 0-20 mA, and 4-20 mA. Output relays for the voltage are either resistive or inductive.
What are some faults that the Multilin 239-RTD-AN-H can protect against? What are typical applications for this motor protection relay?
Typical applications and reasons for installation of this relay are to protect against some common mechanical faults. For example this product can detect a closed discharge valve or loss of suction. This product can also protect against mechanical jam and protect from operator fault by using a thermal memory lockout feature. The GE 239-RTD-AN-H has these and other features making this product an ideal choice for electrical protection of motors.
