Product FAQs
6 answersWhat enclosures and panelboards are compatible with the FXD63B080 breaker?
This 3-pole FD-frame breaker is designed for installation in Siemens P1, P2, P3, P4, and P5 panelboards. It is also compatible with SB switchboards and motor control centers.
What are the accepted wire sizes and materials for the lugs on this breaker?
The factory terminal lugs accept conductor sizes ranging from 6 AWG up to 350 kcmil. They are rated for use with both copper (Cu) and aluminum (Al) wire.
How does the adjustable magnetic trip function operate on the FXD63B080?
The continuous thermal rating is fixed at 80 amps to provide long-time overcurrent protection, while the magnetic trip is adjustable. This allows electricians to fine-tune the instantaneous short-circuit pickup level for better coordination with other protective devices.
Is the FXD63B080 rated for direct current (DC) applications?
Yes, in addition to its AC ratings, this Sentron breaker is approved for DC electrical systems. It provides an interrupting capacity of 30kA at 250VDC and 18kA at 500VDC.
What is the current generation replacement for the FXD63B080?
The Siemens 3VA5 series, specifically the 3VA5280-5ED31-0AA0, serves as the modern replacement for legacy FXD63B080 units. Note that retrofitting the new 3VA breaker into P1, P2, or P3 panelboards will require an appropriate strap kit.
What does the letter B designate in the FXD63B080 catalog number?
The B in the part number indicates that the breaker is equipped with a standard thermal-magnetic trip unit that is calibrated for a 40 degrees Celsius ambient operating temperature.
