E3050 50 Amp Circuit Breaker

E3050 50 Amp Circuit Breaker

The E3050 circuit breaker is a 3-pole, 50-amp thermal-magnetic breaker designed for use in electrical distribution systems that require dependable circuit protection in legacy panelboards and switchgear. Built with a non-interchangeable trip unit, this breaker provides fixed trip characteristics that help safeguard conductors and connected equipment from overloads and short circuits. Rated 10k A.I.C. at 240VAC, the E3050 is intended for applications where moderate fault current interruption capacity is required. With a 40°C ambient temperature rating and included load terminals, this breaker is engineered for consistent operation in commercial and industrial electrical systems where maintaining proper form, fit, and function with existing equipment is essential. Its durable construction reflects the long service life expected of molded-case circuit breakers used in established electrical installations.
