Product FAQs
6 answersWhat is the modern replacement for the obsolete FH26100BC circuit breaker?
The legacy F-frame FH26100BC has been discontinued by Schneider Electric. It is directly replaced by the PowerPact B-Frame series, specifically catalog numbers like the BJA261004 or BGA261004, which offer the same 100A, 2-pole, phase BC connection for I-Line panelboards.
What does the "BC" suffix indicate on this Square D circuit breaker?
The "BC" suffix specifies the phase connection for the I-Line busbar. It means this 2-pole breaker is factory-configured to plug directly into the B and C phases of an I-Line panelboard or switchboard.
Can I install the FH26100BC in a standard QO or Homeline load center?
No. This is an I-Line style plug-in molded case circuit breaker designed exclusively for Square D I-Line panelboards and switchboards. It is not compatible with residential QO, Homeline, or standard unit-mount enclosures.
Can the FH26100BC be utilized in direct current (DC) systems?
Yes, this breaker is certified for DC applications up to 250VDC. When used in a DC system, it provides a 10kA interrupting capacity.
What are the conductor requirements for the FH26100BC lugs?
The factory-installed lugs accept wire gauges from 14 AWG to 1/0 AWG. They are dual-rated for both copper and aluminum conductors. Ensure proper torque is applied during installation as specified on the breaker faceplate.
Are the trip settings adjustable on the FH26100BC?
No, this legacy F-frame breaker features a fixed thermal-magnetic trip unit. Both the Long-Time (thermal) and Instantaneous (magnetic) trip functions are factory-set and non-adjustable.
