DK2350 - 350Amp Circuit Breaker

DK2350 - 350 Amp Circuit Breaker

The DK2350 thermal magnetic circuit breaker is engineered for dependable protection in high-demand electrical distribution systems where consistent performance and safety are essential. Built on a K-Frame platform and rated at 350 amperes with a 65kA interrupting capacity at 240VAC, this two-pole breaker helps safeguard equipment and conductors from overloads and short circuits. Its thermal magnetic trip mechanism responds to both prolonged overcurrent and instantaneous fault conditions, offering balanced protection for commercial and industrial power systems. Designed for operation in 40°C ambient environments and carrying an HACR rating, the DK2350 is suitable for heating, air conditioning, and refrigeration equipment as well as other heavy-duty electrical applications. With non-interchangeable trip units and included line and load lugs, installation is straightforward while maintaining the integrity and reliability expected from a K-Frame breaker.
