Information About 239-RTD-AN

The 239-RTD-AN is a motor protection relay manufactured by GE Consumer and Industrial, specifically under the Multilin product line. Designed to ensure the safety and reliability of motor operations, this relay utilizes Resistance Temperature Detectors (RTDs) to monitor and protect motors from thermal overloads and other hazardous conditions. The 239-RTD-AN relay is essential in industrial applications where motor safety and longevity are critical, providing comprehensive protection and monitoring capabilities.

This relay is designed to operate with an insulation voltage of up to 300 V, offering robust electrical isolation and protection. It is equipped with a fuse rating of 5 x 20 mm, rated at 250 V and 2.5 A, which safeguards the internal circuitry against overcurrent conditions. The inclusion of these fuses ensures that the relay can handle unexpected electrical surges or faults without compromising its functionality, thereby maintaining the safety of the entire motor protection system.

One of the key features of the 239-RTD-AN is its accurate overload protection capabilities. The relay offers trip time accuracy within ±1% of the displayed value, ensuring precise response to overload conditions. This high level of accuracy minimizes the risk of motor damage due to overheating, protecting the motor by triggering timely shutdowns when abnormal temperature rises are detected. The precise overload curves allow for tailored protection settings, ensuring compatibility with a wide range of motor types and operational requirements.

The 239-RTD-AN provides programmable outputs, allowing users to configure the relay for specific applications. The programmable parameters include thermal capacity, percentage of full load, and phase current. These programmable settings provide flexibility, enabling the relay to adapt to different motor protection strategies and operational demands. This customization capability makes the 239-RTD-AN suitable for a variety of industrial environments, ensuring optimal protection and operational efficiency.

In terms of electromagnetic compatibility, the relay is designed to withstand interference from external radio frequency sources, passing RFI tests with a 50 MHz/15 W transmitter. This capability ensures that the relay operates reliably even in environments with high levels of electromagnetic interference, maintaining its performance and accuracy. The ability to resist RFI is crucial in industrial settings where multiple electronic devices operate simultaneously, reducing the likelihood of false trips and ensuring consistent protection.

The 239-RTD-AN relay features short circuit and ground trip settings with adjustable trip levels ranging from 1 to 11 times the current transformer primary (CT PRI) or can be set to off. This adjustable trip level provides flexibility in configuring the relay to protect against various short circuit and ground fault conditions, enhancing the overall safety of the motor and connected equipment. The ability to fine-tune these settings allows for precise protection, tailored to the specific needs of the motor and application.

The relay operates effectively across a wide storage temperature range, from -40 to 158°F, ensuring reliability in diverse environmental conditions. This broad temperature tolerance makes the 239-RTD-AN suitable for use in various climates, including harsh industrial environments where temperature extremes are common. Its durability under such conditions ensures long-term operational stability, reducing maintenance needs and extending the service life of both the relay and the protected motors.

The 239-RTD-AN also features an adjustable unbalance delay setting, ranging from 0 to 60 seconds. This delay allows the relay to accommodate transient conditions and momentary imbalances without triggering unnecessary trips, thus providing stable and reliable motor protection. The ability to adjust the unbalance delay helps prevent nuisance trips, ensuring continuous operation under normal conditions while still protecting the motor from prolonged unbalanced states that could lead to damage.

Overall, the GE Multilin 239-RTD-AN motor protection relay is a versatile and reliable solution for safeguarding motors in industrial applications. Its combination of accurate overload protection, programmable outputs, and robust construction ensures that it meets the demanding requirements of modern motor protection. By integrating the 239-RTD-AN relay into motor control systems, operators can enhance the safety, reliability, and efficiency of their operations, ensuring the longevity and optimal performance of critical motor assets.
