U.S. imports of automatic circuit breakers (not exceeding 1,000 volts) (SITC 77252) totaled $223.7M in April 2026, traded with 57 countries.
Importers of Automatic Circuit Breakers (Not Exceeding 1,000 Volts) paid $14.8M in duties in April 2026 — an effective duty rate of 13% on $117.0M in dutiable value, based on actual customs collections rather than the published tariff schedule. Automatic Circuit Breakers (Not Exceeding 1,000 Volts) imports of $223.7M in April 2026 ran 10% above the year-to-date monthly average of $203.0M.
Last updated: April 2026 dataAutomatic circuit breakers rated at or below 1,000 V are foundational components in residential panels, commercial building electrical systems, and industrial motor-control centers, making them among the most actively traded low-voltage protection devices. Key specification distinctions for classification and procurement include interrupting rating (kA), pole configuration (single, double, triple), and trip mechanism type (thermal-magnetic vs. electronic). Chinese-origin circuit breakers in this category have been subject to Section 301 tariffs, a factor that has driven notable sourcing shifts toward alternative manufacturing countries.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
The interrupting rating (expressed in kiloamperes) is a performance specification rather than a classification criterion under SITC 77252 — all automatic circuit breakers for circuits not exceeding 1,000 V fall within this heading regardless of their kA rating. However, the interrupting rating is commercially critical for procurement and may affect which HTS 10-digit subheading applies under the US tariff schedule, so importers should confirm the correct line with a customs broker.
Yes. Both MCCBs and MCBs are automatic circuit breakers and classify within this heading provided their rated voltage does not exceed 1,000 V. The distinction between them is a commercial and engineering one; for tariff purposes, the voltage threshold is the controlling criterion.
