Product FAQs
6 answersWhat enclosures or panels are compatible with the FAL34070?
This legacy F-frame breaker is a unit-mount device designed for older Square D switchboards, motor control centers, and individual enclosures that accommodate feed-thru wiring.
What are the specific magnetic hold and trip values for the FAL34070?
The instantaneous magnetic protection is fixed, featuring an 800A hold current and a 1450A trip current.
Which standard lugs are used on the FAL34070 and what wire do they accept?
The factory AL100FA lug kit is standard for this amperage range. It accommodates one 14 to 1/0 AWG copper wire or one 12 to 1/0 AWG aluminum wire per terminal.
Is the FAL34070 still in active production?
No, Schneider Electric and Square D have discontinued the legacy F-frame series. For complete system upgrades, this model is typically replaced by the modern PowerPact H-frame line, such as the HGL36070.
Does this breaker plug onto a standard panelboard bus?
No, the FAL34070 is a unit-mount circuit breaker. It mounts independently via mounting screws and relies on wire lugs for both line and load connections rather than plugging or bolting onto a panelboard busbar.
Can the FAL34070 be utilized in DC systems?
Yes, it is rated for up to 250VDC with a 10kA interrupting capacity, allowing integration into industrial DC control panels or specialized distribution systems.
