Product FAQs
7 answersWhat panelboards accept the BGA260504 circuit breaker?
This breaker mounts directly into Square D I-Line panelboards and switchboards. It utilizes a plug-on I-Line connection on the line side and mechanical lugs on the load side.
Can I use the BGA260504 to replace legacy F-frame breakers?
Yes, the PowerPacT B-frame is the modern replacement for legacy Square D FA and FH series breakers. It maintains the same 1.5-inch per pole width, allowing direct substitution in I-Line panels without requiring blank fillers.
What does the 4 at the end of the BGA260504 catalog number signify?
The 4 indicates the specific phase connection for the I-Line bus. For this 2-pole breaker, it specifies a BC phase connection.
What interrupting capacity does the G rating provide on this B-frame breaker?
The G performance level delivers 65 kAIC at 240VAC, 35 kAIC at 480VAC, and 18 kAIC at 600VAC. It also carries a 20 kAIC rating for 250VDC systems.
What is the required lug torque for the BGA260504 terminals?
The load-side mechanical lugs should be torqued to 31.9 to 38.9 lb-in for 14 to 10 AWG wire, and 44.3 to 54.9 lb-in for 8 to 2/0 AWG aluminum or copper wire.
How does the thermal-magnetic trip unit operate on this 50A breaker?
The breaker uses a fixed thermal element for long-time overload protection and a fixed magnetic element for instantaneous short-circuit protection. The dual-break rotating contacts also help reduce peak let-through current during a fault.
Is the BGA260504 HACR rated?
Yes, this PowerPacT B-frame circuit breaker is HACR rated, making it suitable for use with heating, air conditioning, and refrigeration equipment.
