Product FAQs
5 answersWhat equipment is compatible with the FXD63B225L circuit breaker?
This 225A FD-frame breaker is designed for installation in Siemens Sentron P1, P2, and P3 panelboards, as well as compatible switchboards and standalone enclosures.
Are lugs included with the FXD63B225L, or do they need to be ordered separately?
The L suffix in the catalog number indicates that line and load lugs (TA1FD350A) are included and factory-installed. These lugs accept 6 AWG to 350 kcmil copper or aluminum conductors.
What is the difference between the FXD63B225 and the FXD63B225L?
The FXD63B225 is the base breaker supplied without lugs. The FXD63B225L is the fully assembled version that includes factory-installed line and load lugs.
Can the trip unit on the FXD63B225L be changed in the field?
No, this breaker features a non-interchangeable thermal-magnetic trip unit. While the magnetic trip is adjustable, the overall trip unit cannot be swapped for a different amperage.
What type of protection does the FXD63B225L provide?
It provides Long-Time (L) and Instantaneous (I) protection against overloads and short circuits using a thermal-magnetic trip mechanism. The thermal element is fixed, while the magnetic trip is adjustable to suit specific application needs.
