8536.30.40.00 - Motor overload protectors

This HTS category, 8536.30.40.00, specifically covers motor overload protectors. These devices are designed to safeguard electric motors from damage caused by excessive current, typically due to overloads, short circuits, or phase imbalances. They function by interrupting the electrical circuit to the motor when predefined current limits are exceeded, thereby preventing overheating and potential burnout. Examples include thermal overload relays and electronic overload relays integrated into motor control systems.

This classification is distinguished from its sibling category, 8536.30.80.00 (Other), which encompasses a broader range of protective apparatus for electrical circuits not specifically identified as motor overload protectors. While both fall under the broader heading of apparatus for protecting electrical circuits, 8536.30.40.00 is narrowly defined for devices whose primary and sole function is the protection of electric motors.

As this is a leaf node within the HTS structure, there are no subcategories to introduce. Therefore, classification within this specific code relies on accurately identifying the apparatus as a motor overload protector based on its intended purpose and operational characteristics. Items that protect general electrical circuits but are not specifically designed for motor protection would fall under the residual category.
