Square D Overload Relay Thermal Unit B2.65 (Lot of 3)

The Square D B2.65 thermal unit is a critical component for overload relays in motor control systems, designed to protect electric motors from overheating due to prolonged overload conditions. These units are part of the Class 9065 series and are compatible with Square D NEMA-style overload relays, such as those in motor starters for industrial applications like pumps, conveyors, and machinery. They operate by melting a eutectic alloy when excessive current generates heat, tripping the relay to disconnect power and prevent motor damage. Key features include reliable thermal protection, easy installation via plug-in design, and precise calibration for specific full-load ampere (FLA) ranges. Advantages over similar products include Square D's reputation for durability and compatibility with a wide range of NEMA sizes, offering better longevity in harsh environments compared to generic alternatives. Drawbacks may include the need for exact matching to motor FLA to avoid nuisance trips or insufficient protection. This lot includes three new-in-box units, ideal for maintenance stock or replacements in manufacturing, HVAC, or water treatment facilities. Based on image analysis, the units appear unused with intact packaging, featuring engraved markings like 'B2.65' and 'OF' on the device. No parent/child assets are attached.
