Description
Featuring a factory-installed 120-240VAC shunt trip, the Square D FC340201021 is a 3-pole, 20A molded case circuit breaker. This legacy F-Frame device allows for remote tripping, making it ideal for complex industrial control and safety systems. Designed for commercial power distribution, it mounts into Square D I-Line panelboards and switchboards. For modern replacements, it crosses over to the HJA36020 equipped with a shunt trip accessory. It delivers 65kAIC at 480VAC and is HACR rated.Specifications

Product FAQs
5 answersHow does the FC340201021 connect to the panelboard?
It utilizes the Square D I-Line plug-on mounting system. The line side features plug-on jaws that connect directly to the panelboard busbar, while the load side uses standard mechanical lugs for wire termination.
What does the 1021 suffix mean on the FC340201021 catalog number?
The 1021 suffix indicates that the breaker is equipped with a factory-installed 120VAC shunt trip. This allows the breaker to be opened remotely via a control signal.
What is the modern replacement for the legacy FC340201021?
The F-Frame series has been superseded by the PowerPact H-Frame. The direct functional replacement is the HJA36020 combined with an S29386 shunt trip accessory to match the 120VAC remote trip capability.
How does the FC frame differ from the standard FA frame?
The FC frame provides a higher interrupting capacity. While a standard FA frame is rated for 18kAIC at 480VAC, the FC340201021 is rated for an extra-high 65kAIC at 480VAC, making it suitable for systems with higher available fault currents.
How can I visually verify if the FC340201021 has tripped?
This breaker features a Visi-Trip indicator. When the breaker trips due to an overcurrent or a shunt trip signal, the handle moves to the center position and a highly visible red indicator appears, making it easy to identify the tripped breaker in a crowded panel.
