Product FAQs
6 answersCan I install the FS340150B in older Westinghouse or Cutler-Hammer panels?
Yes. Because Eaton acquired the Cutler-Hammer and Westinghouse distribution equipment lines, this Series C F-frame breaker is backward compatible with legacy Cutler-Hammer and Westinghouse panelboards, switchboards, and motor control centers that accept F-frame breakers.
How is the FS340150B mounted inside an electrical enclosure?
This is a unit-mount, feed-thru circuit breaker. It bolts directly to the chassis or mounting pan rather than plugging onto a busbar, making it suitable for standalone enclosures, switchboards, and motor control centers.
Does the FS340150B require a separate lug kit for installation?
No, this breaker includes factory-installed line and load lugs. The terminals are ready to accept 4 AWG to 4/0 AWG copper or aluminum wiring right out of the box.
What is the current replacement model for the FS340150B?
The Eaton FDB3150 is the direct replacement for this breaker. It shares the exact same F-frame dimensions, 150A rating, and 14 kAIC at 480VAC interrupting capacity.
Is the FS340150B rated for use in direct current (DC) applications?
Yes. In addition to its AC ratings, this thermal-magnetic breaker is rated for 250VDC systems, providing a 10 kAIC interrupting capacity for DC control panels or battery applications.
Does this breaker provide adjustable overcurrent protection?
No, the FS340150B features a non-interchangeable, fixed thermal-magnetic trip unit. Both the long-time overload and instantaneous short-circuit trip points are factory set and cannot be adjusted in the field.
