Product FAQs
8 answersDoes the FXD63B200 come with mounting lugs installed?
No. The "B" in the FXD63B200 catalog number indicates that the breaker is supplied without lugs. Lug kits, such as the TA1FD350A, must be purchased separately based on your specific wire type and size requirements.
What wire sizes do the recommended TA1FD350A lugs accept?
When equipped with the standard TA1FD350A lug kit, the breaker accepts one wire per terminal ranging from #6 AWG to 350 kcmil for copper wire, or #4 AWG to 350 kcmil for aluminum wire.
What type of trip unit is installed on this breaker?
The FXD63B200 features a non-interchangeable thermal-magnetic trip unit. It has fixed thermal protection and an adjustable magnetic trip setting, providing long-time and instantaneous (LI) overcurrent defense.
How does the adjustable magnetic trip function on the FXD63B200?
You can tune the instantaneous trip threshold using the dials on the face of the breaker. This allows you to accommodate specific motor inrush currents and coordinate with downstream protection devices to prevent nuisance tripping.
What is the difference between the FXD63B200 and the FD63B200?
The primary difference is the trip unit design. The FXD63B200 features a non-interchangeable trip unit, meaning the thermal-magnetic protection is permanently sealed within the frame. The FD63B200 uses an interchangeable trip unit, allowing you to swap the trip mechanism if your current rating requirements change.
Can the FXD63B200 replace older ITE FD-frame breakers?
Yes. The FXD63B200 serves as a direct drop-in replacement for equivalent older ITE and Siemens FD-frame breakers. It maintains the same physical dimensions and bolt-on mounting configuration, making it ideal for servicing existing distribution systems.
What enclosures or panels is the FXD63B200 compatible with?
This FD-frame breaker mounts in Siemens Sentron P1, P2, and P3 panelboards, as well as compatible switchboards, motor control centers (MCCs), and standalone enclosures. It uses a standard unit-mount, bolt-on connection.
Can I install this breaker in a reverse-feed application?
Yes. The Siemens FXD63B200 is HACR-rated and UL-listed for reverse-feed applications, allowing power to be supplied to the load side terminals if required by your electrical design.
