DK2300 - 300AMP Circuit Breaker

DK2300 - 300 AMP Circuit Breaker

The DK2300 300A 2-pole thermal magnetic circuit breaker is designed to provide dependable overcurrent protection for demanding commercial and industrial electrical systems. Built on the K-Frame DK platform, this breaker combines a high interrupting capacity of 65kA at 240VAC with a non-interchangeable trip unit engineered for stable, predictable protection against overloads and short circuits. The thermal magnetic trip mechanism reacts quickly to fault conditions while maintaining steady performance under normal load variations. With line and load lugs included, installation is straightforward, helping electricians and maintenance teams keep projects moving efficiently. Rated for 40°C operation and HACR applications, the DK2300 is commonly selected for HVAC equipment, panelboards, and heavy-duty distribution systems where reliable circuit protection is essential for safety and uptime.
