Product FAQs
7 answersDoes the KDB3400FT32ZGW come with line and load lugs?
No. The "ZGW" suffix in the catalog number indicates this breaker is supplied without terminals. You must source compatible K-frame lug kits separately, such as the 3TA400K or 3TA401K, depending on your required wire size.
What wire sizes can be used with this breaker?
Because the KDB3400FT32ZGW ships without terminals, the wire capacity depends entirely on the lug kit you install. Standard Eaton kits like the 3TA400K accept 3/0 AWG to 250 kcmil conductors, while the 3TA401K accepts up to 500 kcmil.
What protection functions are included in the FT32 trip unit?
The "FT32" designation means this breaker is equipped with a Digitrip 310+ electronic trip unit featuring LSI functions. This allows for adjustable Long-Time, Short-Time, and Instantaneous trip settings for precise system coordination.
Does the Digitrip 310+ trip unit on this breaker require a rating plug?
No. The Digitrip 310+ electronic trip unit used in the KDB3400FT32ZGW features adjustable switches for continuous current settings, eliminating the need for a separate rating plug.
Does the KDB3400FT32ZGW provide ground fault protection?
No. This breaker features an LSI trip unit. If your installation requires equipment ground fault protection, you will need a breaker with an LSIG trip unit, typically indicated by an "FT36" suffix in the Eaton Series C catalog.
Is the KDB3400FT32ZGW suitable for reverse feed applications?
Yes. Eaton Series C K-frame circuit breakers equipped with Digitrip 310+ electronic trip units are suitable for reverse feed installations.
Can I install the KDB3400FT32ZGW in standard Eaton panelboards?
Yes, this breaker mounts in Eaton Series C panelboards, switchboards, and motor control centers configured for K-frame molded case circuit breakers.
