DK2300W - 300Amp Circuit Breaker

DK2300W - 300 Amp Circuit Breaker

The DK2300W thermal magnetic circuit breaker is designed to deliver dependable circuit protection for demanding electrical distribution systems that require high interrupting capacity and consistent performance. Built on a K-Frame platform, this 2-pole, 300-amp breaker provides protection against overloads and short circuits using a proven thermal magnetic trip mechanism with a non-interchangeable trip unit, ensuring stable and predictable operation over time. With a 65kA interrupting rating at 240VAC, the DK2300W is well suited for facilities where higher available fault currents require reliable interruption capability. Engineered for operation in environments up to 40°C, and carrying an HACR rating, this breaker is frequently used in HVAC systems, commercial electrical distribution, and industrial power panels where consistent protection is essential. Its compact K-Frame footprint helps maximize panel space while maintaining strong performance in demanding electrical applications.
