Eaton Cutler Hammer E2M3800MWWA06U66 800A 3 Pole Molded Case Mining Circuit Breaker – Bolt On – 600VAC

The Eaton Cutler Hammer E2M3800MWWA06U66 is a high-capacity molded case mining circuit breaker designed for demanding industrial and mining power distribution systems. Rated at 800 amps with a 3-pole configuration, it incorporates an interchangeable magnetic-only trip unit that delivers instantaneous short-circuit protection, typically used in systems where overload protection is provided separately. This configuration includes both the A06 auxiliary switch for breaker status indication and the U66 undervoltage release with LED indicator for enhanced operational safety and automatic tripping under low-voltage conditions. Built with a rugged molded case and bolt-on mounting design, it ensures reliable performance in harsh environments up to 600VAC.
