Description
Built to handle severe electrical faults, this 35A current-limiting breaker protects critical commercial and industrial equipment. The specialized design significantly reduces let-through energy to safeguard downstream devices. It mounts securely into traditional Square D enclosures and motor control centers using standard AL100FA lugs. Facilities looking to modernize can substitute this unit with the newer HJL26035 model. Fixed thermal and magnetic trip elements deliver consistent performance.Specifications

Product FAQs
6 answersWhat types of equipment is the FCL24035 compatible with?
This unit mount breaker is designed for installation in traditional Square D enclosures, switchboards, and motor control centers that accept legacy F-frame circuit breakers.
What does the current limiting designation mean for the FCL frame?
As a current limiting breaker, it is engineered to clear severe electrical faults extremely fast. This significantly reduces the peak let-through energy, providing enhanced protection for downstream devices and wiring against thermal and magnetic stress during a short circuit.
What wire sizes are accepted by the lugs on this breaker?
The included AL100FA line and load side lugs accept 14 to 1/0 AWG copper wire, or 12 to 1/0 AWG aluminum wire.
Does this breaker include lugs for both the line and load sides?
Yes, this feed-thru circuit breaker comes equipped with standard lugs on both the line and load sides for immediate wire termination.
Is the Square D FCL24035 still actively manufactured?
The FCL frame is a legacy molded case circuit breaker. For new installations or modernizations, Square D has superseded this series with the PowerPact H-frame, such as the HJL26035. However, the FCL24035 remains widely used for direct replacements in existing systems.
How does the thermal magnetic trip unit in this breaker operate?
The fixed thermal element provides delayed tripping for sustained overloads, while the fixed magnetic element trips immediately in the event of a severe short circuit. This combination ensures comprehensive protection for commercial and industrial circuits.
