Product FAQs
5 answers
What panelboards accept the FC34060 circuit breaker?
This breaker is specifically designed for installation in Square D I-Line panelboards and switchboards. It is not compatible with standard bolt-on or QO style load centers.
How is the FC34060 installed into the panelboard?
It utilizes an I-Line style plug-in connection. The line side of the breaker features jaws that press directly onto the panelboard bus assembly, while the load side uses standard mechanical lugs for wire termination.
Is the Square D FC34060 still manufactured?
The FC frame is a legacy product that has been phased out of active production by Schneider Electric. For new infrastructure upgrades, it is typically replaced by the PowerPact H-frame series, such as the HJA36060, though the FC34060 remains available for maintaining existing I-Line systems.
What does the C in the FC frame designation represent?
In Square D F-frame breakers, the second letter indicates the interrupting capacity. The C in FC designates a high interrupting rating, providing 65kAIC at 480VAC, which is higher than standard FA or FH frame breakers.
What type of protection does the LI trip function provide?
The LI designation means the thermal-magnetic trip unit includes Long-time and Instantaneous functions. The long-time thermal element protects against sustained overloads, while the instantaneous magnetic element responds immediately to high-level short circuits.
