Challenger CE2020 U is a two‑pole molded‑case circuit breaker rated for 20A on 480V circuits, designed to interrupt fault currents and protect conductors in electrical panel installations. This Challenger device is intended for panelboard use to provide protective switching for two conductors in 480V systems. As part of Challenger’s legacy line, the CE2020 U offers a compact, reliable MCCB solution for industrial and commercial distribution applications where 480V service is present. Typical uses include safeguarding branch circuits and motor control feeders within 480V distribution panels, where a 20A maximum current rating is required.
