Appleton ADR20033 U ANSI Rated Circuit Breaker

Appleton ADR20033‑U is a Powertite 200 A, 600 V pin‑and‑sleeve receptacle designed for rugged industrial power connections. This three‑pole, three‑wire device uses grounding style 1 construction and accepts 2/0 AWG through 250 MCM conductors via solid brass pressure‑wire terminals with BeCu springs for durable, repeatable terminations. Rated for 50–400 Hz and 250 VDC, the ADR20033‑U is intended for portable or fixed equipment such as motor generators, welders, pumps, compressors, and cellular relay stations, and it mates with ADR20033 receptacle bodies and ARC20033E connector bodies to form a complete Powertite system. The housing is copper‑free (4/10 of 1 percent max), contributing to resistance in demanding environments, while the 600 VAC rating suits heavy‑duty distribution in industrial facilities. The unit accommodates a 2‑inch hub and maintains the 3P3W arrangement to ensure proper alignment with mating plugs. Widely used in industrial power distribution, ADR20033‑U provides a robust, high‑current receptacle option for 600 V service when paired with compatible Appleton components.
