If you’re looking for a reliable, heavy-duty circuit breaker that can handle serious power without breaking a sweat, the Eaton MDL3800 is one you can count on. This 800-amp molded case breaker is part of Eaton’s well-known Series C, built specifically for tough industrial and commercial environments where performance, safety, and long-term durability matter most. Whether you're outfitting a large facility or replacing an older breaker, the MDL3800 gives you the confidence that your electrical systems are protected — even under high load or short-circuit conditions. And despite its power, it doesn’t take up much space, making installation easier in tight electrical panels.
