DK2250 - 250Amp Circuit Breaker

DK2250 - 250 Amp Circuit Breaker

The DK2250 thermal magnetic circuit breaker is designed to deliver dependable circuit protection for demanding electrical distribution systems operating at up to 240VAC. Built on the K-Frame DK platform, this 2-pole, 250-amp breaker provides strong interruption capability with a 65kA A.I.C. rating, helping safeguard equipment and conductors from overloads and short circuits. Its thermal magnetic trip mechanism responds accurately to both sustained overload conditions and instantaneous fault events, making it a practical solution for commercial and industrial environments where reliable protection is critical. Rated for 40°C operation and HACR applications, the DK2250 supports installations involving heating, air conditioning, and refrigeration systems. The unit features a non-interchangeable trip unit for consistent protection settings and includes line and load lugs, helping simplify installation and ensure secure conductor connections in panelboards and switchboards.
