DK2350Y - 350Amp Circuit Breaker

DK2350Y - 350 Amp Circuit Breaker

The DK2350Y 350 Amp circuit breaker is built to handle demanding electrical distribution systems where dependable overcurrent protection is critical. Designed on the K-Frame DK platform, this 2-pole thermal magnetic breaker responds quickly to both overload conditions and sudden short circuits, helping protect wiring, equipment, and connected loads from electrical damage. With a 65kA interrupting rating at 240VAC, it is suitable for installations where available fault current levels are high and safety margins matter.

This breaker is HACR rated, making it a practical choice for heating, air-conditioning, and refrigeration equipment, as well as other large electrical loads commonly found in commercial and industrial environments. It operates at 40°C ambient conditions, supporting consistent performance in electrical rooms and equipment spaces where temperatures can rise above standard room levels. The non-interchangeable trip unit keeps protection settings fixed and reliable, while the included line-side lugs allow for straightforward wiring during installation. For facilities that require a dependable 350-amp protection device within the DK frame family, the DK2350Y offers a simple and effective solution.
