Product FAQs
6 answersCan I use both aluminum and copper wire with the standard lugs on the DK2250?
Yes, the factory-installed line and load lugs are dual-rated for both aluminum and copper (Al/Cu) conductors. They accommodate wire sizes from 3 AWG up to 350 kcmil. Ensure proper torque specifications are followed during installation.
Is the DK2250 suitable for use in motor control centers?
Yes, this K-Frame molded case circuit breaker is compatible with Eaton Series C motor control centers, as well as standard Series C panelboards and switchboards.
Can the Eaton DK2250 be used in direct current (DC) applications?
Yes, this thermal-magnetic breaker is rated for DC systems up to 250VDC, providing an interrupting capacity of 10 kAIC for direct current applications.
Are the thermal and magnetic trip settings adjustable on the DK2250?
No, the DK2250 features a fixed thermal and fixed magnetic trip unit. If your application requires adjustable trip settings, you will need to select a different Series C K-Frame model with an adjustable magnetic or electronic trip unit.
Does the Eaton DK2250 replace older Cutler-Hammer models?
Yes, Eaton and Cutler-Hammer are the same brand for this product line. The DK2250 directly replaces older Cutler-Hammer DK2250 breakers, maintaining the exact same physical dimensions and Series C K-Frame footprint.
What type of fault protection does the LI trip function provide?
The LI designation indicates Long-Time and Instantaneous trip functions. The long-time thermal element protects against sustained overloads, while the instantaneous magnetic element provides immediate tripping during short-circuit faults.
