Description
Engineered for demanding environments, the Square D FAL320301021 is a 3-pole, 30A molded case circuit breaker delivering reliable thermal-magnetic (LI) protection. This F-Frame breaker utilizes a unit-mount design for Square D enclosures and control panels. It can be replaced by the modern PowerPact B-Frame (BDL36030). The factory-installed 120-240VAC shunt trip allows remote circuit tripping. It provides a 10kAIC rating at 240VAC and carries an HACR rating for HVAC equipment.Specifications

Product FAQs
6 answersWhat does the "1021" suffix indicate on the FAL320301021?
The "1021" suffix denotes a factory-installed 120/240VAC shunt trip. This accessory allows the circuit breaker to be opened remotely via an external control signal, which is commonly used for emergency stops or automated safety systems.
What is the modern replacement for the obsolete FAL320301021?
Schneider Electric has replaced the legacy F-Frame series with the PowerPacT B-Frame. The direct modern equivalent is the BDL36030. To maintain the remote trip functionality of the original "1021" suffix, you will also need to add a compatible 120/240VAC shunt trip accessory to the new B-Frame breaker.
How is the FAL320301021 mounted in a system?
This is a unit-mount, feed-thru circuit breaker. Instead of plugging into a load center bus or bolting onto an I-Line panelboard, it mounts individually to a backpan or mounting plate within Square D enclosures, switchboards, or control panels, and wires directly to the line and load lugs.
Can I use aluminum wire with the FAL320301021?
Yes, the factory lugs are dual-rated for both copper and aluminum conductors. They accept 14 to 4 AWG copper wire or 12 to 4 AWG aluminum wire.
Are the thermal and magnetic trip settings adjustable on this breaker?
No, the FAL320301021 features a fixed thermal-magnetic trip unit. Both the long-time (overload) and instantaneous (short-circuit) trip thresholds are factory-set and cannot be adjusted in the field.
What does the "LI" trip function code mean for this MCCB?
The "LI" designation indicates that the thermal-magnetic trip unit provides Long-Time (L) protection against sustained overloads and Instantaneous (I) protection against severe short circuits.
