8535.29.00.40 - Other

This category, HTS code 8535.29.00.40, encompasses automatic circuit breakers designed for voltages exceeding 1,000 volts that do not fall under the specific subheading for circuit breakers rated for 345 kV or more. These devices are crucial for the protection and control of electrical circuits in high-voltage applications, automatically interrupting the flow of current in the event of overloads or short circuits to prevent damage to equipment and ensure safety. The classification here focuses on automatic circuit breakers whose voltage ratings are below the threshold specified in the sibling category.

The primary distinction between this category and its sibling, 8535.29.00.20, lies in their voltage rating. While both cover automatic circuit breakers for voltages exceeding 1,000 V, this specific "Other" category is for those with voltage ratings below 345 kV. This implies that a circuit breaker rated at, for example, 138 kV would be classified here, whereas one rated at 400 kV would be classified under the sibling category. The underlying function of circuit protection remains the same, but the specified voltage rating is the determining factor for proper classification.

As a leaf node within the HTS, there are no further subcategories for HTS code 8535.29.00.40. Therefore, classification at this level relies on identifying automatic circuit breakers for voltages above 1,000 V that are not specifically covered by the "345 kV or more" designation. Importers and exporters should carefully verify the voltage rating of their automatic circuit breakers to ensure accurate classification within the appropriate subheading.
