Product FAQs
6 answersWhat does the "C" suffix in the FY14030C catalog number indicate?
The "C" suffix indicates that this 1-pole breaker is factory-configured to connect specifically to the C-phase of an I-Line panelboard busbar.
What type of panelboards accept the FY14030C circuit breaker?
It is designed exclusively for Square D I-Line panelboards and switchboards. The plug-in jaw connects directly to the I-Line busbar stack.
Can the FY14030C be used in direct current (DC) applications?
Yes, this breaker is rated for up to 125VDC with a 10kA interrupting capacity, making it suitable for specific DC control circuits or battery systems.
What type of trip mechanism does this breaker use?
It utilizes a fixed thermal-magnetic trip unit. The thermal element provides an inverse time delay for overloads, known as the Long-Time function, while the magnetic element provides instantaneous tripping for short circuits.
How does the I-Line connection mount to the panelboard?
The breaker features a plug-in jaw that engages directly with the I-Line busbar. A mounting bracket and screw secure the off end of the breaker to the panelboard backpan.
Is the Square D FY frame still in active production?
The FY frame is a legacy molded case circuit breaker that has been discontinued by the manufacturer. It is often replaced by modern PowerPact series breakers or sourced as a direct drop-in replacement to maintain the existing panel configuration without busbar modifications.
