Product FAQs
7 answersWhat does the 1021 suffix mean on the FAL341001021 circuit breaker?
The 1021 suffix indicates that this breaker includes a factory-installed 120/240VAC shunt trip. This accessory allows the breaker to be tripped remotely for enhanced control and safety, often used with emergency stop buttons or fire alarm systems.
What types of panels or enclosures is the FAL341001021 compatible with?
This unit-mount F-frame breaker is designed for use in Square D enclosures, control panels, and switchboards. It features a feed-thru connection type and mounts using standard lugs, rather than plugging into an I-Line bus.
What wire sizes are accepted by the lugs on the FAL341001021?
The factory lugs accept 14 to 1/0 AWG copper wire or 12 to 1/0 AWG aluminum wire. Ensure proper torque specifications are followed during installation to prevent terminal overheating.
Can the FAL341001021 be used in DC applications?
Yes, this thermal-magnetic breaker is rated for up to 250VDC with an interrupting capacity of 10kA. It is suitable for use in battery systems, solar applications, or industrial DC control panels.
Is the FAL341001021 still manufactured, or is there a modern replacement?
The FAL series is a legacy F-frame breaker. The modern designated replacement is the PowerPact B-frame BDL36100, which will also require a compatible shunt trip accessory to match the 1021 suffix functionality.
What type of protection does the FAL341001021 provide?
This thermal-magnetic breaker provides both long-time overload protection and instantaneous short-circuit protection. Both the thermal and magnetic trip settings are fixed, meaning they cannot be adjusted in the field.
How does the FAL341001021 mount into a panel?
This is a unit-mount, feed-thru circuit breaker. It does not plug onto a busbar. Instead, it fastens directly to the enclosure or backpan and uses lugs on both the line and load sides for wire connections, making it ideal for standalone enclosures or custom control panels.
