DK2350 - 350Amp Circuit Breaker

DK2350 - 350Amp Circuit Breaker

When your facility depends on reliable power distribution, replacing a circuit breaker isn't just about matching the amperage rating—it's about maintaining the integrity of the entire electrical system. The Eaton DK2350 is a 350 Amp, 2-pole molded case circuit breaker designed for applications that require the form, fit, and function of an Eaton Series C K-Frame breaker. Commonly found in commercial buildings, industrial facilities, and heavy-duty electrical distribution systems, this breaker provides the overcurrent protection needed to help keep equipment and power systems operating safely.

For maintenance teams, electrical contractors, and facility managers, finding a compatible replacement breaker can help avoid unnecessary modifications to existing equipment. The DK2350 is built to match the original design requirements of systems that utilize Eaton K-Frame breakers, making it a practical solution for repair projects, preventative maintenance programs, and equipment restoration work. Its 350 Amp rating, two-pole configuration, and 65kA interrupting capacity at 240VAC make it suitable for applications where substantial fault-current protection is required.

In the field, breakers like the DK2350 are often found protecting feeder circuits, distribution equipment, and larger electrical loads throughout commercial and industrial facilities. When an existing breaker reaches the end of its service life or has been damaged by a fault condition, replacing it with the correct frame size and electrical ratings helps keep the system configured as originally intended.
