Product FAQs
6 answersWhat equipment is compatible with the FD63B100 breaker?
This unit-mount breaker is designed for use in Siemens P1 (as a subfeed), P2, P3, P4, and P5 panelboards, as well as compatible switchboards and motor control centers.
What wire sizes do the standard lugs on this breaker accept?
The standard lugs accommodate 6 AWG to 350 kcmil copper conductors, or 4 AWG to 350 kcmil aluminum conductors.
How is the trip unit configured on this Sentron FD-frame breaker?
It features a thermal-magnetic trip unit with fixed thermal protection for long-time overloads and an adjustable magnetic setting for instantaneous short-circuit protection.
Can I use the FD63B100 to replace an older ITE breaker with the same catalog number?
Yes. Siemens acquired ITE and continued manufacturing the Sentron series. A Siemens FD63B100 is a direct replacement for an older ITE FD63B100.
How does this breaker mount into the enclosure?
The FD63B100 is a unit-mount, or bolt-on, circuit breaker. It bolts directly to the equipment chassis or mounting pan rather than plugging into a busbar.
Is this breaker suitable for direct current applications?
Yes, this model is rated for DC systems up to 500VDC, providing an interrupting capacity of 18kA for direct current installations.
