Product FAQs
5 answersWhat is the modern replacement for the Square D FA34080-1021?
The FA34080-1021 is a legacy F-frame circuit breaker. The direct modern replacement is the Square D PowerPact H-frame series, specifically the HDA36080. To match the -1021 suffix functionality, the replacement requires a field-installable or factory-installed 120/240VAC shunt trip accessory.
What does the "-1021" suffix mean on this Square D circuit breaker?
The "-1021" suffix indicates that the breaker includes a factory-installed 120/240VAC shunt trip. This allows the circuit breaker to be tripped remotely for emergency shutdowns or control system integration.
Does the FA34080-1021 provide a visual indication when it trips?
Yes, Square D FA series breakers feature a Visi-Trip indicator. The handle drops to a distinct mid-position to provide a clear visual indication when the breaker has tripped due to an overcurrent or short circuit condition, separating a fault trip from a manually opened breaker.
Can I install the FA34080-1021 in a standard QO or Homeline load center?
No. This breaker features an I-Line plug-in connection and is designed exclusively for commercial and industrial Square D I-Line panelboards and switchboards. It will not fit in residential QO or Homeline load centers.
How does the shunt trip mechanism wire into the control circuit?
The factory-installed 120/240VAC shunt trip includes control wires that exit the breaker housing. These wires must be connected to an external control switch or relay that provides the required voltage to activate the trip coil during an emergency or automated shutdown.
