Product FAQs
7 answersCan the BDL36125LU be used to replace older Square D F-frame circuit breakers?
Yes, the PowerPacT B-frame series serves as a modern, compact replacement for legacy 125A F-frame breakers like the FAL36125. Because the B-frame has a smaller footprint, retrofitting this unit-mount breaker into existing enclosures may require a DIN rail or a specific adapter plate.
What does the LU suffix indicate on the BDL36125LU catalog number?
The LU suffix specifies the terminal configuration. It indicates that the breaker is equipped with EverLink lugs on both the line and load ends, and includes a factory-installed control wire terminal specifically on the ON (line) end lugs.
How is the BDL36125LU circuit breaker mounted?
This is a unit-mount circuit breaker that offers flexible installation options. It features traditional back-pan mounting using screws, as well as integrated DIN rail mounting that snaps directly onto a standard 15 x 35 mm DIN rail.
What are the benefits of the EverLink lugs included on this breaker?
The EverLink lugs are designed with a patented creep-compensating mechanism that prevents cables from loosening over time. This ensures a durable, long-term connection for both aluminum and copper conductors ranging from 14 AWG to 3/0 AWG.
How does the BDL36125LU handle high short circuit faults?
PowerPacT B-frame breakers utilize dual-break rotating contacts. During a short circuit fault, this design significantly reduces the peak current and let-through energy, providing enhanced protection for downstream electrical equipment.
Does this breaker include a manual testing feature?
Yes, it features an integral push-to-trip button located on the front cover. This allows electricians and panel builders to manually trip the breaker to verify the mechanical integrity of the tripping mechanism during maintenance.
Can the BDL36125LU be installed in an I-Line panelboard?
No, the BDL36125LU features a unit-mount construction intended for back-pan or DIN rail mounting in industrial control panels and switchboards. It does not have the plug-on jaw connections required for Square D I-Line panelboards.
