Product FAQs

8 answers
What does the -1380 suffix indicate on the FAL34070-1380?

The -1380 suffix denotes that this breaker includes a factory-installed 120-240V AC shunt trip and a 1A/1B auxiliary switch for remote tripping and status signaling.

What wire sizes are accepted by the lugs on the FAL34070-1380?

The factory-installed lugs accept 14 AWG to 1/0 AWG copper wire, or 12 AWG to 1/0 AWG aluminum wire.

Are the trip settings adjustable on the FAL34070-1380?

No, this F-Frame breaker features a thermal-magnetic trip unit with fixed long-time and fixed instantaneous trip functions. It does not have adjustable dials.

How is the FAL34070-1380 mounted?

This is a unit-mount, feed-thru circuit breaker. It is designed to be surface-mounted or installed in Square D enclosures, switchboards, and motor control centers using its line and load side lugs, rather than plugging onto a busbar.

Is the FAL34070-1380 part of the current Square D product line?

The FAL series is a legacy F-Frame molded case circuit breaker. For new installations, Square D typically recommends crossing this to the modern PowerPacT B-Frame series, though the FAL remains widely used for direct replacements.

Can the FAL34070-1380 be used in DC applications?

Yes, this circuit breaker is rated for DC applications up to 250V DC, with an interrupting capacity of 10kA.

Can this 3-pole breaker be used on a single-phase system?

Yes, 3-pole molded case circuit breakers can generally be used on single-phase systems by wiring through two of the three poles, provided the voltage and amperage ratings meet the application requirements.

What type of protection does the FAL34070-1380 provide?

It features a thermal-magnetic trip unit that provides long-time (thermal) protection against overloads and instantaneous (magnetic) protection against short circuits.
