Engineered for commercial power distribution, this 15-amp, two-pole molded case circuit breaker delivers reliable thermal-magnetic protection. The PowerPacT B-Frame design offers robust performance in a compact footprint. This unit installs into standard I-Line panelboards and switchboards. It serves as an exact replacement for legacy FA24015AB breakers, simplifying facility upgrades. Rated 18 kAIC at 480V, it features an AB phase connection and dual-break rotating contacts.
What legacy Square D circuit breakers does the BDA24015Y1 replace?
The PowerPacT B-frame BDA24015Y1 is the direct replacement for legacy 15A, 2-pole FA and FH series I-Line circuit breakers. It maintains the same mounting space dimensions to allow for easy retrofitting in existing I-Line panelboards.
What does the Y1 suffix indicate in the BDA24015Y1 catalog number?
The 1 in the Y1 suffix indicates that this 2-pole I-Line circuit breaker is factory-configured for an AB phase connection. When installed in an I-Line panelboard, it will connect to the A and B phases of the busbar.
How much mounting space does this 2-pole B-frame breaker require in an I-Line panelboard?
This 2-pole PowerPacT B-frame circuit breaker requires 3 inches of mounting space in a standard Square D I-Line panelboard.
Is the BDA24015Y1 rated for 100 percent continuous current?
No, this is a standard-rated circuit breaker. It is designed to be applied continuously at up to 80 percent of its 15A rating in accordance with the National Electrical Code.
What type of wire connections are standard on the load side of this breaker?
The BDA24015Y1 comes factory-equipped with mechanical lugs on the load side (OFF end) that accept 14 AWG to 2/0 AWG copper or aluminum wire. The line side (ON end) features the standard I-Line plug-on jaw connection.
Does this breaker feature adjustable trip settings?
No, the BDA24015Y1 has a fixed thermal magnetic trip unit. Both the long-time overload and instantaneous short circuit trip functions are factory-set and cannot be adjusted in the field.
What is the benefit of the dual-break rotating contacts in this PowerPacT B-frame breaker?
The dual-break rotating contact design reduces the amount of peak current during a short circuit fault. This lowers let-through currents and enhances overall equipment protection.
