Product FAQs
6 answersWhich panelboards are compatible with the F3070 circuit breaker?
This bolt-on breaker is designed for use in legacy Westinghouse panelboards, Eaton Pow-R-Line C panelboards, and compatible motor control centers.
What wire gauge range do the load side lugs on the F3070 accept?
The standard load side lugs accommodate wire sizes from 14 AWG up to 1/0 AWG. Ensure proper torque specifications are followed during installation.
Can the F3070 be used to replace an FDB3070 breaker?
Yes, the F3070 shares the same physical dimensions and mounting configuration as the FDB3070, allowing it to serve as a direct replacement in existing enclosures without modification.
Is the F3070 circuit breaker suitable for reverse feed applications?
Yes, this breaker features reverse feed compatibility, allowing it to be back-fed in applications where the power source is connected to the load terminals.
How does the thermal-magnetic trip unit in the F3070 protect electrical circuits?
The fixed thermal-magnetic trip unit uses a bimetallic strip to provide Long-Time (L) protection against sustained overloads, while an electromagnet provides Instantaneous (I) protection to quickly clear short circuits.
Is the F3070 still actively manufactured by Westinghouse?
No, Westinghouse circuit breakers are legacy products. However, Eaton acquired the Westinghouse distribution equipment line and continues to support these legacy F-frame applications.
