DK2300Y - 300Amp Circuit Breaker

DK2300Y - 300 Amp Circuit Breaker

The DK2300Y 300 Amp 2-pole circuit breaker is designed to protect electrical distribution systems where higher current capacity and dependable fault protection are essential. Built on a K-Frame design, this thermal magnetic breaker helps guard equipment and wiring against both overload conditions and sudden short circuits. The thermal portion of the trip mechanism responds to sustained overcurrent, while the magnetic element reacts quickly to high-fault events, helping reduce the risk of damage to connected systems. With an interrupting capacity of 65kA at 240VAC, the DK2300Y is well suited for installations where available fault current levels are higher than standard applications. The breaker includes a non-interchangeable trip unit, meaning its protection settings are matched to the device at the factory for consistent operation. Line-side lugs are included, allowing conductors to be connected quickly during installation. Rated for 40°C environments and HACR applications, this breaker is commonly used in electrical systems that power HVAC equipment and other heavy-duty loads in commercial and industrial facilities.
