8535.90 - Other:

Category 8535.90 encompasses electrical apparatus for switching or protecting circuits, or for making connections, designed for voltages exceeding 1,000 V, that are not specifically classified under other headings within 8535. This broad category includes a variety of specialized electrical components used in high-voltage applications.

While siblings like fuses (8535.10), automatic circuit breakers, and isolating/make-and-break switches (8535.30), as well as lightning arresters, voltage limiters, and surge suppressors (8535.40), cover specific protective and switching functions, 8535.90 acts as a residual category for other high-voltage electrical connection and protection devices. For instance, it would not include devices primarily designed for low-voltage circuits, nor those covered by more specific headings elsewhere in Chapter 85.

Within this category, two subcategories exist to further refine classification. Subcategory 8535.90.40 specifically addresses motor starters and motor overload protectors, essential for controlling and safeguarding electric motors in high-voltage industrial settings. The remaining items fall under 8535.90.80, which represents "Other" apparatus not falling into the motor starter/protector classification, requiring careful examination of their specific function and design to ensure correct classification within this broad "other" designation.
