Description
Part of Square D's legacy F-frame lineup, the FCL34030 provides robust current-limiting protection for commercial and industrial applications. This 3-pole, 30A breaker restricts let-through energy during a fault, minimizing thermal and magnetic stress on downstream components. It mounts into standard Square D enclosures, switchboards, and motor control centers. Rated for 65 kAIC at 480VAC, it features fixed thermal-magnetic trip units and is the predecessor to the modern HJL36030.Specifications

Product FAQs
6 answersWhat equipment is compatible with the FCL34030?
This unit-mount breaker is designed for installation in traditional Square D enclosures, switchboards, and motor control centers.
What wire sizes are supported by the standard lugs on this breaker?
The terminals accept 14 to 1/0 AWG copper conductors or 12 to 1/0 AWG aluminum conductors.
How does the current-limiting feature of the FCL34030 protect downstream devices?
During a severe short circuit, the breaker clears the fault extremely fast to restrict let-through current. This minimizes thermal and magnetic stress on downstream electrical components.
What is the modern replacement for the legacy FCL34030?
The FCL series is a legacy F-frame breaker. Facilities looking to modernize can substitute this unit with the newer PowerPact H-frame series, specifically the HJL36030 model.
Does this breaker plug onto a busbar?
No. The FCL34030 utilizes a unit-mount, feed-thru connection. It must be bolted or fastened directly to the mounting surface or backpan rather than plugging into an I-Line bus.
Are the trip settings adjustable on this model?
No. This breaker features a thermal-magnetic trip unit with fixed thermal and fixed magnetic elements for its Long-Time and Instantaneous (LI) protection functions.
