8536.20.00.20 - Molded case

This HTS category, 8536.20.00.20, specifically covers "molded case" automatic circuit breakers. These are designed for switching or protecting electrical circuits with a voltage not exceeding 1,000 volts. The defining characteristic of items classified here is their construction: they are enclosed within a molded plastic or composite case, providing robust protection and insulation for the internal circuit-breaking components. This design is typical for circuit breakers used in residential, commercial, and industrial electrical distribution systems.

It is crucial to distinguish this category from its sibling, 8536.20.00.40, which is designated for "Other" automatic circuit breakers. While both fall under the umbrella of automatic circuit breakers, the "molded case" designation is for those specifically constructed with a molded enclosure. The "Other" category would encompass automatic circuit breakers that do not meet this specific construction criteria, perhaps those with open frames, metal enclosures, or other specialized designs not falling under the molded case definition.

As this is a leaf node, there are no further subcategories. Therefore, classification within 8536.20.00.20 hinges on accurately identifying an automatic circuit breaker whose primary housing is formed by a molded case. This includes a wide array of thermally or magnetically tripped devices intended for overcurrent and short-circuit protection, provided they are encased in a molded material.
