Description
Built to handle demanding electrical loads, this 50A thermal-magnetic breaker ensures reliable long-time and instantaneous overcurrent defense. It integrates into Square D I-Line panelboards requiring a BC phase connection. When modernizing equipment, engineers typically replace this legacy F-Frame unit with the current HGA260504 model. The device supports 14-1/0 AWG wiring and includes a high interrupting capacity of 25kA at 480VAC for robust industrial power distribution.Specifications

Product FAQs
7 answersWhat does the "BC" suffix mean in the FH26050BC catalog number?
The "BC" suffix indicates that this 2-pole I-Line circuit breaker is factory-configured to connect to the B and C phases of the panelboard bus. This is critical for balancing loads across the phases in your Square D I-Line panelboard.
How does the FH26050BC mount into a panelboard?
It utilizes an I-Line style plug-in connection on the line side, which snaps directly onto the bus stack of a Square D I-Line panelboard. The load side features standard mechanical lugs for wire termination.
What wire sizes are compatible with the load-side lugs on the FH26050BC?
The factory-installed load lugs accommodate 14 AWG to 1/0 AWG copper wire, or 12 AWG to 1/0 AWG aluminum wire.
What is the modern replacement for the legacy FH26050BC circuit breaker?
When modernizing equipment, engineers typically replace this legacy F-Frame unit with the current PowerPact H-Frame equivalent, such as the HGA260504 model.
Can the FH26050BC be used in DC applications?
Yes, this thermal-magnetic breaker is rated for use in DC circuits up to 250V DC, providing an interrupting capacity of 10kA.
Are the trip settings adjustable on the FH26050BC?
No, this breaker features a fixed thermal-magnetic trip unit. Both the long-time (thermal) and instantaneous (magnetic) trip functions are factory set and cannot be adjusted in the field.
What does the "LI" trip function code indicate on this breaker?
The "LI" designation means the breaker provides Long-Time (thermal) protection against overloads and Instantaneous (magnetic) protection against short circuits.
