Description
Built to handle 70-amp loads, this three-pole F-Frame breaker provides essential overcurrent and short-circuit protection. It integrates seamlessly into commercial switchboards and standalone enclosures requiring standard unit-mount hardware. The device utilizes AL100FA lugs for secure wire terminations on both the line and load sides. For modern upgrades, facility engineers often transition to the BDL36070, but this legacy unit remains critical for maintaining existing infrastructure.Specifications

Product FAQs
6 answersWhat is the modern replacement for the legacy Square D FAL32070 circuit breaker?
The FAL32070 is a legacy F-Frame breaker. For modern upgrades, facility engineers and panel builders transition to the PowerPact B-Frame series, specifically the BDL36070, which offers the same 70A, 3-pole configuration with updated features.
What are the recommended lug torque specifications for the FAL32070?
The FAL32070 uses AL100FA mechanical lugs on both the line and load sides. The recommended tightening torque for these lugs is 49.56 lbf-in (5.6 N.m) for the accepted wire range of 14 to 1/0 AWG copper or 12 to 1/0 AWG aluminum.
What types of equipment is the FAL32070 compatible with?
This unit-mount, bolt-on breaker is designed for use in compatible Square D enclosures, switchboards, and unit-mount panelboards. It is not compatible with I-Line panelboards, which require specialized plug-on phase connections.
Does the FAL32070 provide protection for DC circuits?
Yes, in addition to its 240VAC rating, the FAL32070 is rated for 250VDC applications. It provides an interrupting capacity of 5kAIC at 250VDC, making it suitable for specific industrial DC control panels and distribution systems.
Can the trip settings on the FAL32070 be adjusted in the field?
No, the FAL32070 features a thermal-magnetic trip unit with fixed thermal and fixed magnetic settings. The long-time and instantaneous trip functions are factory-calibrated and non-interchangeable to ensure consistent overcurrent and short-circuit protection.
How is the FAL32070 mounted within a panel?
The FAL32070 is a unit-mount circuit breaker, meaning it bolts directly to the back pan or mounting plate of a switchboard or enclosure rather than plugging onto a busbar.
