DK2250Y - 250Amp Circuit Breaker

DK2250Y - 250Amp Circuit Breaker

When your electrical distribution system calls for a 250 Amp, 2-pole molded case circuit breaker, the Eaton DK2250Y delivers the form, fit, and function needed to help keep existing equipment operating as intended. Part of Eaton's trusted DK Series K-Frame lineup, this thermal magnetic circuit breaker is designed to protect circuits from overloads and short circuits while meeting the electrical requirements of compatible commercial and industrial systems.

The DK2250Y features a 65 kAIC rating at 240 VAC, making it suitable for applications where higher available fault current levels must be addressed. Its thermal magnetic trip mechanism provides dependable protection by responding to both sustained overload conditions and instantaneous fault events. Because it utilizes a non-interchangeable trip unit, the breaker maintains the trip characteristics originally specified for the equipment, an important consideration when replacing an existing unit.

Whether you're performing routine maintenance, restoring existing equipment, or replacing a failed breaker, the Eaton DK2250Y offers a practical solution for maintaining system compatibility without altering the original design of the electrical distribution system. Built to last and engineered for long-term service, it remains a dependable choice for keeping critical power systems protected and operating efficiently.
