Description
Providing essential long-time and instantaneous protection, this 30-amp, 3-pole molded case circuit breaker is built for demanding commercial environments. This unit-mount breaker integrates smoothly into legacy Square D switchboards and enclosures. When upgrading, the HDL36030 serves as a suitable replacement alongside the S29450 auxiliary switch. A factory-installed 1A/1B auxiliary switch provides reliable feedback on breaker status. The device carries a 25kAIC rating at 240VAC.Specifications

Product FAQs
8 answersWhat does the -1212 suffix mean on the FAL34030-1212?
The -1212 suffix indicates that this breaker includes a factory-installed 1A/1B auxiliary switch. This provides one normally open (NO) and one normally closed (NC) contact for remote status signaling and control circuit integration.
Can I install the FAL34030-1212 in a Square D I-Line panelboard?
No. This is a unit-mount, feed-thru circuit breaker designed for standard enclosures, switchboards, and traditional panelboards. It lacks the plug-on jaw connections required for I-Line distribution panels.
What wire sizes are accepted by the AL50FA lugs on this breaker?
The factory-installed AL50FA line and load lugs are rated to accept 14 AWG to 4 AWG copper wire, or 12 AWG to 4 AWG aluminum wire.
Can the FAL34030-1212 be used in direct current (DC) systems?
Yes, this breaker is rated for DC applications up to 250VDC, where it provides a 10kA interrupting capacity.
Are the trip settings adjustable on the FAL34030-1212?
No. This breaker utilizes a fixed thermal-magnetic trip unit. The long-time (thermal overload) and instantaneous (magnetic short-circuit) trip points are factory-calibrated and cannot be adjusted in the field.
What is the modern replacement for the legacy FAL34030-1212?
The legacy Square D F-frame series has been largely replaced by the modern PowerPact B-frame series. When upgrading or replacing, a PowerPact B-frame breaker with equivalent auxiliary switch accessories is typically used, though mounting modifications may be required.
Does the FAL34030-1212 provide ground fault protection?
No. This is a standard thermal-magnetic molded case circuit breaker designed for overload and short-circuit protection. It does not feature integrated ground fault or arc fault protection.
How is the FAL34030-1212 mounted?
This breaker is a unit-mount device, meaning it is secured using mounting screws or brackets rather than plugging onto a busbar. It is commonly installed in standalone Square D enclosures or bolted into switchboards.
