Description
Utilizing a compact B-Frame footprint, this 40-amp molded case circuit breaker delivers essential long-time and instantaneous (LI) protection. The design is optimized for commercial facilities. The unit snaps into Square D I-Line panelboards via a specialized AB phase connection. Contractors deploy this configuration to swap out obsolete FA26040AB breakers without modifying the buswork. Carrying a D-interrupting capacity of 18 kAIC at 480VAC, it safely isolates downstream faults.Specifications

Product FAQs
6 answersWhat panelboards are compatible with the BDA260401 circuit breaker?
The BDA260401 is designed exclusively for Square D I-Line panelboards and switchboards. It features an I-Line style plug-on connection for the line side and should not be installed in panels from other manufacturers.
Does the PowerPacT B-frame replace older Square D circuit breakers?
Yes, the PowerPacT B-frame series, including the BDA260401, is the direct replacement for legacy Square D F-frame circuit breakers, such as the FA and FH series. It maintains the same I-Line mounting footprint to allow for easy retrofitting in existing panels.
What is the recommended lug torque for the BDA260401?
For the load side mechanical lugs, the tightening torque is 31.9 to 38.9 lbf-in for 14 to 10 AWG wire, and 44.3 to 54.9 lbf-in for 8 to 2/0 AWG wire. Always verify exact torque specifications on the breaker faceplate before installation.
What do the letters in the BDA260401 catalog number signify?
In the PowerPacT nomenclature, "B" designates the B-frame size, "D" indicates the interrupting rating tier (18kA at 480VAC), and "A" specifies the I-Line plug-on mounting style.
What are the magnetic trip settings for this 40A breaker?
The BDA260401 features a fixed thermal-magnetic trip unit. The instantaneous magnetic trip is factory-set to hold at 400A and trip at 600A.
How does the BDA260401 connect to the panel bus?
It utilizes the Square D I-Line mounting system, which features plug-on jaws on the ON end (line side) that snap directly onto the panelboard bus, and mechanical lugs on the OFF end (load side) for wire termination.
