Description

Engineered for remote shutdown applications, the FAL340801021 includes a factory-installed 120VAC shunt trip alongside its standard thermal-magnetic protection. This legacy F-frame MCCB from Square D provides long-time and instantaneous (LI) trip functions for commercial and industrial systems. It mounts into standard enclosures, switchboards, and motor control centers. Delivering an 18 kAIC rating at 480VAC, this breaker is replaced by the modern PowerPact HGL36080 series.

Product FAQs

5 answers
What does the 1021 suffix indicate on the FAL340801021 catalog number?

The 1021 suffix signifies that this breaker comes with a factory-installed 120V to 240V AC shunt trip. This accessory allows for remote tripping of the breaker, which is commonly used for emergency shutdown systems or remote control applications.

Will the FAL340801021 fit into a Square D I-Line panelboard?

No, this is a unit-mount circuit breaker designed for feed-thru connections. It must be hard-mounted using screws in standard enclosures, switchboards, or motor control centers. It lacks the plug-on brackets required for I-Line panelboard installations.

Are the trip settings on the FAL340801021 field adjustable?

No, this breaker is built with fixed thermal and fixed magnetic trip elements. The long-time and instantaneous protection parameters are factory calibrated and cannot be modified by the user.

How should the shunt trip on the FAL340801021 be wired?

The factory-installed shunt trip requires a dedicated 120V to 240V AC control power source. When voltage is applied to the shunt trip coil terminals, it mechanically trips the breaker to open the primary contacts. All control wiring must comply with local electrical codes.

What modern breaker series replaces the legacy Square D FAL frame?

The legacy F-frame breakers, including the FAL series, have been superseded by the modern Square D PowerPact series, such as the B-frame or H-frame. When crossing over to a PowerPact replacement, you must add a separate shunt trip accessory to match the remote tripping functionality of the 1021 suffix.
