Product FAQs
5 answersWhat panelboards are compatible with the FC34080-1021 circuit breaker?
This I-Line style plug-in breaker is designed exclusively for use in Square D I-Line panelboards and switchboards. It will not fit in standard load centers.
What does the -1021 suffix indicate on this Square D circuit breaker?
The -1021 suffix designates a factory-installed 120VAC shunt trip accessory. This allows the breaker to be tripped remotely via a separate control circuit, which is often required for emergency shutdown systems.
How much mounting space does the FC34080-1021 require in an I-Line panelboard?
As a 3-pole F-frame breaker, it occupies 4.5 inches of bus space, which equates to 1.5 inches per pole on the I-Line bus assembly.
How does the FC frame compare to other Square D F-frame breakers?
The FC frame designates a higher interrupting capacity tier. While standard FA frames are rated 18kA at 480V and FH frames are 25kA, the FC frame provides a 65kA interrupting rating at 480V for systems with higher available fault currents.
Is the FC34080-1021 part of a current production series?
The FC frame is part of the legacy Square D F-frame series. It is commonly sourced to maintain or expand existing I-Line panelboards without needing to retrofit the panel for the newer PowerPact series replacements.
