Product FAQs
8 answersWhat does the "B" in the FXD63B175 catalog number signify?
The "B" indicates that this FXD6 circuit breaker ships from the factory without lugs installed. Line and load lugs must be sourced separately.
Which lugs are compatible with the FXD63B175?
You can install Siemens TA1FD350A lugs for aluminum or copper wire ranging from #6 AWG to 350 kcmil, or use TC1FD350 lugs for copper wire only.
Can the FXD63B175 be reverse fed?
Yes. Because it is built with a non-interchangeable trip unit, the FXD63B175 is UL Listed for reverse-fed applications.
What is the difference between the FXD63B175 and the FD63B175?
The FXD63B175 features a non-interchangeable trip unit, which allows it to be reverse fed. The FD63B175 has an interchangeable trip unit. Both are 175-amp, 3-pole, FD-frame breakers that ship without lugs.
What panels are compatible with this Sentron FD-frame breaker?
This breaker is compatible with Siemens P1, P2, P3, P4, and P5 panelboards, as well as SB switchboards and motor control centers.
Is the trip unit on this breaker adjustable?
It features a thermal-magnetic trip unit with fixed thermal (long-time) protection and an adjustable magnetic (instantaneous) trip function to help coordinate with downstream devices.
Is the FXD63B175 rated for both AC and DC applications?
Yes. In addition to its AC ratings, this breaker is rated for DC systems. It provides up to a 30kA interrupting capacity at 250VDC and 18kA at 500VDC.
What does the LI trip function code mean for this breaker?
The LI designation means the breaker provides Long-Time (L) thermal protection against continuous overloads and Instantaneous (I) magnetic protection against short circuits.
