Product FAQs
6 answersIs the Square D FAL36070 circuit breaker obsolete?
Yes, the FAL series is a legacy F-frame molded case circuit breaker and is considered obsolete by the manufacturer. It has been superseded by the Square D PowerPact H-frame series for new installations. However, exact replacements like the FAL36070 are commonly sourced to maintain existing panels without requiring an equipment retrofit.
Can I replace the FAL36070 with a modern PowerPact H-frame breaker?
While the PowerPact H-frame series is the current generation replacement for legacy F-frame breakers, they do not share the exact same physical dimensions. Upgrading to an H-frame breaker in an existing switchboard or motor control center typically requires a specific mounting adapter or structural modifications to the panel.
What enclosures are compatible with the FAL36070 breaker?
This 70-amp unit mount breaker can be installed in several Square D 100-amp F-frame enclosures. Standard compatible models include the FA100S for NEMA 1 surface mounting, the FA100F for NEMA 1 flush mounting, and the FA100RB for NEMA 3R outdoor applications.
What does the LI trip function indicate on this breaker?
The LI designation indicates a thermal-magnetic trip unit featuring Long-Time (L) and Instantaneous (I) protection. The thermal bimetal element provides delayed inverse-time protection against overloads, while the electromagnetic assembly provides immediate protection against short circuits. Both the thermal and magnetic trip settings on this model are fixed.
How is the FAL36070 mounted within a panel?
This is a unit-mount circuit breaker, frequently referred to as a feed-thru or panel-mount breaker. It bolts directly to the backpan of the enclosure and requires wire connections at both the line and load side mechanical lugs. It is not compatible with plug-on I-Line panelboards.
Are mechanical lugs included with the FAL36070?
Yes, the L in the FAL prefix indicates that this unit-mount breaker comes equipped with factory-installed mechanical lugs on both the line and load sides. These dual-rated terminals accept copper conductors from 14 to 1/0 AWG and aluminum conductors from 12 to 1/0 AWG.
