Product FAQs
8 answersWhat panelboards are compatible with the FC34015G?
This breaker is designed exclusively for Square D I-Line panelboards and switchboards. It features an I-Line style plug-in connection for the line side.
What does the G suffix in the FC34015G catalog number indicate?
The G suffix indicates that the breaker includes a factory-installed ground fault shunt trip. It is designed to be used in conjunction with an external Square D ground fault sensor module, such as the GFM100FA.
Can I use this breaker to replace a standard FA or FH I-Line breaker?
Yes, the FC frame shares the same physical dimensions and I-Line mounting as FA and FH breakers, but offers a higher interrupting capacity of 65kA at 480V. However, ensure your application requires the G suffix ground fault shunt trip before substituting.
Is the FC34015G still manufactured, or is there a modern replacement?
The FC34015G is a legacy F-frame breaker. The modern equivalent is the PowerPact H-frame series, such as the HJA36015. However, because this specific breaker has a G suffix for external ground fault modules, you must verify compatibility with your existing ground fault system before upgrading.
How does the I-Line connection work on the FC34015G?
The breaker features a blow-on plug-in jaw connection on the line side that attaches directly to the I-Line busbar. The load side uses standard mechanical lugs for wire termination.
What wire sizes are accepted by the lugs on this breaker?
The factory-installed load side lugs accept 14 AWG to 1/0 AWG copper wire, or 12 AWG to 1/0 AWG aluminum wire.
Can the FC34015G be used in DC power systems?
Yes, this thermal magnetic breaker is rated for DC applications up to 250VDC, with an interrupting capacity of 10kA.
What type of trip unit does this breaker use?
It uses a fixed thermal magnetic trip unit with Long-Time and Instantaneous functions to protect against overloads and short circuits.
