Product FAQs
7 answersWhat legacy circuit breakers does the BGA261001 replace?
The PowerPacT B-Frame BGA261001 is a direct upgrade and exact replacement for legacy 100A, 2-pole FA and FH series breakers, specifically the FA26100AB and FH26100AB. It maintains the same mounting space dimensions for seamless retrofits in existing I-Line panelboards.
What is the phase connection for the BGA261001?
This breaker is factory-configured for an AB phase connection. It is designed to plug directly into the A and B phases of a Square D I-Line panelboard or switchboard bus.
How is the line and load connection configured on this breaker?
The line side (ON end) utilizes the I-Line plug-in jaw connection that mounts directly to the panelboard bus. The load side (OFF end) is equipped with mechanical lugs that accept 14 AWG to 2/0 AWG copper or aluminum wire.
Can I install this PowerPacT B-Frame breaker in a standard QO or Homeline load center?
No. The BGA261001 features an I-Line style plug-in connection designed exclusively for commercial and industrial Square D I-Line panelboards and switchboards. It is not compatible with residential QO or Homeline load centers.
Are the trip settings adjustable on the BGA261001?
No, this breaker features a non-interchangeable, fixed thermal-magnetic trip unit. Both the long-time (thermal overload) and instantaneous (magnetic short-circuit) trip functions are factory-set and cannot be adjusted in the field.
What does the LI trip function code indicate on the BGA261001?
The LI designation indicates that the thermal-magnetic trip unit provides Long-Time (L) and Instantaneous (I) protection. The Long-Time function protects the circuit against sustained overloads, while the Instantaneous function provides immediate tripping during severe short circuits.
Does the BGA261001 support field-installable accessories?
Yes, Square D PowerPacT B-frame breakers support a variety of field-installable accessories, including auxiliary contacts, alarm switches, shunt trips, and undervoltage releases. These accessories can be added without increasing the overall footprint of the breaker.
