Product FAQs

6 answers
What panelboards are compatible with the FH26020 circuit breaker?

This breaker is designed specifically for Square D I-Line panelboards and switchboards. It utilizes the specialized I-Line plug-on mounting system for its phase connections.

What is the difference between Square D FH and FA frame circuit breakers?

The FH series offers a higher interrupting capacity compared to the standard FA series. The FH26020 delivers up to 65kA at 240VAC and 25kA at 480VAC, making it appropriate for electrical systems with higher available fault currents.

Is the FH26020 rated for direct current applications?

Yes, this breaker is rated for use on DC systems up to 250VDC, where it provides a 50kA interrupting rating.

What wire sizes do the terminals on the FH26020 accept?

The standard lugs on this breaker accommodate wire gauges from 14 AWG to 4 AWG. Both copper and aluminum conductors are accepted.

Has the Square D FH26020 been replaced by a newer series?

Yes, the legacy F-frame series is obsolete. For modern upgrades in existing I-Line panelboards, Schneider Electric replaced these with the PowerPact B-frame and H-frame series circuit breakers.

How does the trip unit function on this breaker?

The breaker features a fixed thermal-magnetic trip unit. The thermal element provides long-time protection against sustained overloads, while the magnetic element delivers instantaneous protection against short circuits.
