Information About 239-AN
The GE Multilin 239-AN Motor Protection Relay is an advanced device designed to provide reliable protection and monitoring for electrical motors. It belongs to the category of contactors and starters, with a specific focus on solid-state overload and relay functions. This relay is engineered to handle a wide range of applications and provides robust features to ensure motor safety and efficiency.
The 239-AN operates with a communication isolation of 36 VDC, utilizing an active source to maintain clear and reliable communication. It supports communication baud rates ranging from 1200 to 12,000 bps, accommodating various data transmission needs and ensuring compatibility with diverse control systems. This flexibility allows for seamless integration into different operational environments.
One of the key features of the 239-AN is its true RMS conversion capability for ground current inputs. This ensures accurate measurement and protection, as it processes up to 16 samples per cycle, which helps in maintaining precise control and monitoring of motor operations. The relay is equipped with switch inputs that require a minimum duration of 100 milliseconds, allowing it to respond promptly to operational changes.
Thermal modeling is a critical aspect of the 239-AN's functionality. It offers programmable lockout cool rates ranging from 1 to 5000 minutes with a tolerance of ±20% power on/off. This feature enables the relay to effectively manage thermal conditions and prevent overheating by adjusting the cooling period according to the specific needs of the motor.
The relay provides separate start and run protection, enhancing its ability to safeguard motors during different operational phases. Additionally, it includes an unbalance range setting from 5 to 100%, with the option to turn off the protection if necessary. This feature is particularly useful for preventing damage due to voltage imbalances or other issues that could affect motor performance.
The 239-AN does not require specific ventilation requirements, simplifying its installation and operation. This relay is designed to deliver reliable protection and precise monitoring, making it an essential component for maintaining motor health and ensuring operational efficiency in various industrial applications.
