About heading 8535

Electrical apparatus for switching or protecting electrical circuits, or for making connections to or in electrical circuits (for example, switches, fuses, lightning arresters, voltage limiters, surge suppressors, plugs and other connectors, junction boxes), for a voltage exceeding 1,000 V

Heading 8535 covers high-voltage electrical apparatus used to switch, protect, or connect circuits, meaning apparatus rated above 1,000 V. It is split first by article type: fuses, automatic circuit breakers, isolating and make-and-break switches, lightning arresters and surge suppressors, and a residual other group. The other group separates motor starters and overload protectors from terminals, splices, couplings, and other connectors.
