8536.20.00.40 - Other

This HTS category, 8536.20.00.40, encompasses automatic circuit breakers that do not fall under the "molded case" designation. It covers a variety of protective devices designed to interrupt electrical circuits in the event of overcurrent or short circuits, thereby preventing damage to equipment and potential fire hazards. These devices are crucial for ensuring the safe and reliable operation of electrical systems.

Distinguishing this category from its sibling, 8536.20.00.20, is key. While both fall under automatic circuit breakers, the "molded case" designation implies a specific construction where the breaker's internal components and operating mechanism are encased in a molded plastic or composite housing. This category, "Other," therefore serves as a residual classification for automatic circuit breakers that do not meet the criteria for molded case construction, potentially including those with different housing materials or designs, such as metal-clad or open-frame circuit breakers, as long as they function automatically to protect electrical circuits.

As a leaf node, this category has no further subdivisions. Therefore, classification here relies on carefully examining the physical and functional characteristics of the automatic circuit breaker to confirm it is not a molded case type and meets the general description of automatic circuit breakers for voltages not exceeding 1,000 V. Examples might include thermal-magnetic breakers with metal enclosures or air circuit breakers designed for industrial applications where the construction deviates from the typical molded case format.
