Product FAQs
5 answersWhat is the difference between the FDB2020 and FDB2020L catalog numbers?
The "L" suffix in FDB2020L indicates that the breaker comes factory-equipped with both line and load side lugs. The base FDB2020 catalog number often refers to the breaker body alone, which may require ordering terminals separately.
Which panelboards and enclosures accept the FDB2020L circuit breaker?
This F-frame breaker is designed for use in Eaton Series C panelboards, legacy Westinghouse panelboards, motor control centers, and switchboards that accept unit-mount, feed-thru breakers.
Can the FDB2020L be used in DC electrical systems?
Yes, this thermal magnetic breaker is rated for up to 250VDC with a 10kAIC interrupting capacity, making it suitable for industrial DC control panels and compatible DC applications.
What wire sizes and materials are compatible with the standard lugs on the FDB2020L?
The included line and load lugs accept 14 AWG to 1/0 AWG wire and are dual-rated for both copper (Cu) and aluminum (Al) conductors.
Does the FDB2020L feature adjustable trip settings?
No, this breaker uses a non-interchangeable thermal magnetic trip unit with fixed long-time and fixed instantaneous (LI) trip functions. The trip curve cannot be adjusted in the field.
