Description
Engineered for reliable power distribution, the FH26030AC is a 30A, 2-pole molded case circuit breaker from Square D. It features an AC phase connection and provides thermal-magnetic protection for 600VAC and 250VDC electrical systems. With a 25kAIC rating at 480VAC, this legacy F-Frame unit easily installs into I-Line panelboards using a plug-on mounting style. When replacing older equipment, this breaker is superseded by the modern HGA260302 H-Frame model for continued facility safety.Specifications

Product FAQs
5 answersWhat does the AC suffix indicate on the FH26030AC part number?
The AC suffix designates the specific phase connection for the I-Line bus. This breaker is configured to connect to the A and C phases in a Square D I-Line panelboard.
How are the line and load connections configured on this breaker?
The line side features an I-Line plug-on connection that mounts directly onto the panelboard bus stack. The load side is equipped with mechanical lugs for terminating the branch circuit conductors.
Is the Square D FH26030AC still in active production?
The FH frame is a legacy F-frame molded case circuit breaker. For new installations or panel upgrades, it is typically superseded by the modern Square D PowerPact H-frame or B-frame series, which offer updated trip units and higher interrupting capabilities.
Can the trip settings on the FH26030AC be adjusted in the field?
No, this breaker features a fixed thermal-magnetic trip unit. Both the long-time overload and instantaneous short-circuit trip functions are factory-set and cannot be modified by the user.
What type of conductors can be used with the load side lugs?
The factory-installed load lugs accept 14 AWG to 4 AWG copper or aluminum wire. Ensure conductors are sized appropriately for the 30A rating and terminated according to local electrical codes.
