Product FAQs
6 answersWhich bus phases does the FH26020AC connect to?
The AC suffix in the catalog number indicates this 2-pole breaker is factory-configured to plug onto the A and C phases of a Square D I-Line panelboard bus.
What is the current replacement for the legacy FH26020AC breaker?
The Square D PowerPacT H-Frame series replaces legacy F-Frame breakers. The HGA260202 is the modern drop-in replacement for the FH26020AC, maintaining the same A and C phase I-Line connection.
Can I install the FH26020AC in a standard Square D QO or Homeline load center?
No. This breaker features an I-Line plug-in mounting style and is exclusively compatible with Square D I-Line panelboards and switchboards.
What wire gauge range do the standard lugs on the FH26020AC accept?
The factory lugs accommodate 14 AWG to 4 AWG copper or aluminum conductors.
Is the FH26020AC suitable for direct current (DC) systems?
Yes, in addition to its AC ratings, this breaker is rated for use in DC systems up to 250VDC, providing 10 kAIC of interrupting capacity.
Are the trip settings on the FH26020AC adjustable?
No. This breaker uses a fixed thermal-magnetic trip unit. Both the long-time (thermal) and instantaneous (magnetic) trip functions are factory-set and non-adjustable.
