DK2250W - 250Amp Circuit Breaker

DK2250W - 250 Amp Circuit Breaker

The DK2250W circuit breaker is a high-capacity 250 amp, 2-pole thermal magnetic circuit breaker built on a dependable K-Frame platform and engineered for consistent protection in demanding electrical distribution systems. Designed to interrupt fault currents up to 65kA at 240VAC, this breaker helps safeguard panelboards, switchboards, and industrial equipment from overloads and short circuits. Its thermal-magnetic trip mechanism provides dual protection—thermal sensing for prolonged overload conditions and magnetic response for instantaneous fault interruption. Rated for 40°C environments and HACR applications, the DK2250W is well suited for HVAC systems and other heavy electrical loads. The non-interchangeable trip unit ensures calibrated performance and dependable operation within the breaker’s designed parameters. Built for professional electrical environments where reliability and safety matter, this breaker is commonly used in commercial and industrial power distribution systems. Please note that line and load lugs are not included, allowing installers to configure connections according to their specific application requirements.
