Last updated: April 2026 dataMolded-case circuit breakers and other automatic overcurrent interruption devices rated at or below 1,000 V are among the most widely specified components in commercial, industrial, and residential electrical distribution panels. The US tariff schedule separates molded-case designs (8536200020) — the dominant commercial form factor — from other automatic circuit breakers (8536200040), a distinction that aligns with industry-standard product families from major switchgear manufacturers. Mexico leads US imports under this heading, with the Dominican Republic a notable second-tier supplier reflecting nearshore assembly operations. Italy and France also appear among top sources, representing European brand-name manufacturers with established US distribution networks.

A molded-case circuit breaker (MCCB) is defined by its insulating housing — the case and cover are formed from molded insulating material that also serves as the structural enclosure. This distinguishes it from open-frame or other breaker designs. The molded-case designation is a recognized industry term aligned with UL 489 and IEC 60947-2 standards, and its use in the tariff line generally tracks that technical definition.
The Dominican Republic hosts assembly operations for major electrical equipment brands serving the North American market, benefiting from geographic proximity and trade preference arrangements. This makes it a competitive nearshore alternative to Asian manufacturing for certain breaker product lines, particularly for brands that have established local production facilities.
