Product FAQs

7 answers
Can the Eaton KD2400 replace an older Westinghouse or Cutler-Hammer KD2400?

Yes, Eaton acquired the distribution equipment lines from Westinghouse and Cutler-Hammer. The Eaton KD2400 is a direct replacement and shares the same physical footprint and electrical ratings as the legacy Westinghouse and Cutler-Hammer models.

Is the KD2400 suitable for reverse feed applications?

Yes, Eaton Series C K-Frame circuit breakers with non-interchangeable thermal-magnetic trip units, such as the KD2400, are suitable for reverse feed use.

What lug kits are compatible with the KD2400?

The KD2400 typically uses the TA400K lug kit for dual 3/0 AWG to 250 kcmil conductors, or the TA401K lug kit for a single 250 to 500 kcmil conductor. Both kits accept copper or aluminum wire.

What is the recommended tightening torque for the lugs on the KD2400?

Torque values vary depending on the specific lug kit installed (such as TA400K or TA401K) and the conductor material. Always verify the exact torque specifications printed on the circuit breaker nameplate or the lug body before finalizing the installation.

What types of enclosures and panelboards can the KD2400 be installed in?

The KD2400 is a unit-mount breaker designed for use in Eaton Series C panelboards, Pow-R-Line 3a and Pow-R-Line 4 panelboards, as well as compatible switchboards and motor control centers.

Does the KD2400 provide ground fault protection?

No, the KD2400 features a standard thermal-magnetic trip unit that provides long-time and instantaneous (LI) protection only. If ground fault protection is required, you will need an electronic trip breaker or an external ground fault relay system.

How does the KD2400 mount into a panelboard?

The KD2400 is a unit-mount, feed-thru circuit breaker. When installing it into a Pow-R-Line panelboard, a specific mounting strap or connector kit is required to attach the breaker to the panel busbars.
