DK2300Y - 300Amp Circuit Breaker

DK2300Y - 300Amp Circuit Breaker

When keeping an electrical distribution system operating safely and reliably, using the correct replacement breaker matters. The Eaton DK2300Y is a 300 Amp, 2-pole thermal magnetic circuit breaker designed for applications that require the form, fit, and function of an Eaton K-Frame breaker. Whether you're installing it in commercial facilities, industrial operations, or HVAC-related equipment, this breaker provides the overcurrent and short-circuit protection needed to help safeguard electrical systems and connected equipment.

In the field, breakers like the DK2300Y are commonly found protecting feeder and distribution circuits that serve larger electrical loads. When an existing breaker needs replacement, matching the original amperage, interrupting rating, and frame size helps maintain the system exactly as it was designed. That's one reason this breaker is frequently used during maintenance projects, equipment repairs, and facility upgrades where preserving compatibility is the primary goal.

The DK2300Y also includes line-side lugs, making it suitable for applications where compatible connection hardware is required. Rated for operation in 40°C ambient temperatures and carrying an HACR rating, it is often used in heating, ventilation, air conditioning, refrigeration, and general power distribution systems throughout commercial and industrial facilities.
