Description
Engineered for commercial power distribution, the Square D FH16020C is a 1-pole, 20A molded case circuit breaker. It utilizes thermal-magnetic trip technology to provide reliable long-time and instantaneous (LI) protection. This legacy F-Frame breaker mounts into Square D I-Line panelboards and features a factory-configured Phase C connection. It serves as an exact maintenance component, though it is officially replaced by the PowerPact B-Frame series (BGA160205) for new installations.Specifications

Product FAQs
7 answersWhat panels are compatible with the FH16020C?
This breaker is designed exclusively for use in Square D I-Line panelboards and switchboards. It features a plug-on mounting design that connects directly to the I-Line bus.
Is the Square D FH16020C still manufactured?
The FH16020C is a legacy F-Frame circuit breaker and is no longer in active production by Schneider Electric. For new installations, it has been replaced by the PowerPact B-Frame series, though the FH16020C remains available as an exact maintenance replacement for existing I-Line panels.
How does the FH16020C mount into the panel?
It utilizes an I-Line plug-on mounting style. The breaker features plug-on jaws that grip the panelboard bus securely, along with a mounting foot and retaining screw to lock it in place.
What is the difference between the Square D FA and FH series breakers?
The primary difference is the interrupting capacity. While both are F-Frame breakers with identical physical dimensions, the FA series offers standard interrupting ratings. The FH series provides high interrupting ratings, making the FH16020C suitable for systems with higher available fault currents.
Does this breaker provide adjustable trip settings?
No, the FH16020C features a fixed thermal magnetic trip unit. Both the long-time thermal overload and instantaneous magnetic short circuit trip functions are factory-calibrated and cannot be adjusted in the field.
Can I install a standard F-Frame lug-to-lug breaker in place of this I-Line breaker?
No. While they may look similar in size, a standard lug-to-lug F-Frame breaker lacks the specialized plug-on jaws and mounting foot required to connect to an I-Line panelboard bus. You must use an I-Line specific breaker like the FH16020C.
What does the "C" at the end of the FH16020C catalog number signify?
The "C" indicates that this single-pole breaker is factory-configured to connect specifically to the C-phase of the I-Line panelboard bus.
