Product FAQs
5 answers
What enclosures or panelboards are compatible with the FDE308033?
This F-frame breaker is designed for use in Eaton Series C panelboards, switchboards, and motor control centers (MCCs). It shares the same physical footprint as standard FD thermal-magnetic breakers.
What does the LS trip function on the FDE308033 allow me to adjust?
The LS designation indicates it features a Digitrip electronic trip unit with adjustable Long-Time (overload) and Short-Time (short circuit) pickup settings. The 33 suffix specifically provides an I2t response for the short delay time function to aid in system coordination.
What wire sizes do the standard lugs on this 80A breaker accept?
The standard line and load terminals accept 14 AWG to 1/0 AWG copper or aluminum wire.
Can the FDE308033 replace an older FD or FDC thermal-magnetic breaker?
Yes, the FDE electronic breaker has the exact same dimensions, footprint, and connector style as the standard FD and FDC breakers. However, you may need to replace the panelboard filler plate when upgrading to the electronic trip version.
Does the FDE308033 include ground fault protection?
No. The 33 suffix indicates Long-Time and Short-Time (LS) protection only. If ground fault protection is required, you must use a breaker with an LSG or LSIG trip unit, such as those with a 35 or 36 suffix.
