GE Multilin 239-AN-H | Motor Protection Relay Conformal Coated

GE Multilin 239-AN-H 3-Phase Motor Protection Relay 250VAC 10A

The 239-AN-H (Model: 239-AN-H) is a high-performance microprocessor-based relay designed to provide comprehensive protection for three-phase AC motors and their associated mechanical equipment. As part of the GE Multilin 239 series, the 239-AN-H (Part Number: 239-AN-H) specifically safeguards against conditions that cause motor damage, such as thermal overload, phase unbalance, and ground faults. This specific "-H" variant is equipped with a Harsh Environment Conformal Coating, protecting the internal circuitry from moisture, dust, and chemical contaminants common in industrial processing.

Beyond electrical protection, the 239-AN-H (Model: 239-AN-H) serves as a diagnostic tool for maintenance engineers. It provides pre-emptive alarms before a process malfunction results in physical damage and allows for detailed post-fault analysis through event recording. By integrating a sophisticated thermal model with programmable logic, the relay prevents motor overheating while allowing for maximum operational efficiency, ensuring long-term reliability for medium-sized motors in manufacturing and utility sectors.
