Product FAQs
6 answersCan I install the FWF1050L in a standard residential loadcenter?
No, the FWF1050L is a unit-mount breaker designed specifically for Eaton Pow-R-Line C panelboards, switchboards, and motor control centers. It is not compatible with standard residential plug-on or bolt-on loadcenters.
What does the "L" suffix indicate on the FWF1050L catalog number?
The "L" indicates that the breaker is factory-supplied with both line and load side terminals (lugs). Standard Eaton F-frame breakers typically come with load terminals only.
What is the difference between the Eaton FWF1050L, FD1050L, and FDB1050L?
These are all 50A, 1-pole Series C F-frame breakers, but they feature different interrupting ratings. The FWF1050L is rated at 40kAIC at 240VAC, the FDB1050L is rated at 18kAIC at 240VAC, and the FD1050L is rated at 65kAIC at 240VAC.
How is the FWF1050L circuit breaker mounted?
The FWF1050L is a unit-mount circuit breaker. This means it bolts directly to the mounting pan or chassis of the panelboard or switchboard, rather than plugging onto a busbar.
Can the FWF1050L be used in 277V or 480V systems?
No, the FWF1050L is strictly rated for a maximum of 240VAC. For 277V or 480V applications, a different breaker series such as the FD or HFD must be specified.
Are the trip settings adjustable on the FWF1050L?
No, the FWF1050L features a fixed thermal and fixed magnetic trip unit. It provides standard long-time and instantaneous (LI) protection without adjustable dials.
