The thermal overload heater identified as W62 from Allen Bradley falls under the Bulletin 500 Accessories series. Its primary function is to safeguard electric motors against overheating caused by overload situations. This device leverages a eutectic alloy for its operation, ensuring that it reacts effectively to excess current conditions, which is critical for motor longevity.

This model is rated under Class 20, making it ideal for specific motor applications. The W62 accommodates a minimum full load current of 23.3 amperes while being capable of managing a maximum full load current of 30.0 amperes. The full load ampere (FLA) ratings vary depending on the NEMA size, facilitating compatibility across different motor configurations: 24.3 A for NEMA sizes 00 to 0, 25.0 A for size 1, 25.7 A for size 2, and 27.5 A for size 3.

Essentially, the W62 thermal overload heater comprises a manual reset mechanism, which is crucial in ensuring safety. After tripping due to excessive load, it requires manual intervention to reset, thus preventing potential damage to the motor from automatic re-engagement. The application of this device extends to motor protection and industrial motor control, making it a reliable choice for various operational needs.
