Description
Designed for complex control schemes, this 100A current-limiting breaker features a factory-installed 120-240VAC shunt trip for remote disconnect applications. The unit-mount configuration integrates seamlessly into Square D commercial enclosures, switchboards, and panelboards. Delivering a massive 200kAIC interrupting capacity at 480VAC, it restricts let-through current to protect sensitive downstream circuits. For modern replacements, use the HRL36100 paired with an S29386 shunt trip.Specifications

Product FAQs
6 answersWhat does the 1021 suffix indicate on the FIL361001021 catalog number?
The 1021 suffix designates that this circuit breaker includes a factory-installed 120-240VAC shunt trip. This allows the breaker to be opened remotely via an external control signal.
Can the FIL361001021 be installed in a Square D I-Line panelboard?
No. The FIL361001021 is a unit-mount circuit breaker designed for base mounting in standard enclosures, switchboards, and panelboards. It does not have the plug-on jaw connections required for I-Line distribution panels.
How does the current-limiting design of the FIL361001021 benefit a power distribution system?
Current-limiting breakers are engineered to clear high-magnitude short circuits in less than half a cycle. This rapid operation significantly reduces peak let-through current and thermal energy, protecting sensitive downstream equipment from severe damage.
What type of trip unit is equipped on the FIL361001021?
This breaker uses a fixed thermal-magnetic trip unit with Long-Time and Instantaneous (LI) functions. The thermal and magnetic trip points are factory set and cannot be adjusted in the field.
What are the wire size requirements for the FIL361001021 lugs?
The factory lugs are rated for dual-rated (Cu/Al) conductors and accept wire sizes from 14 AWG to 1/0 AWG. Always apply an approved oxide inhibitor when terminating aluminum conductors.
Is the FIL361001021 part of a current production series?
The FIL361001021 belongs to the legacy Square D F-frame family, which has been largely transitioned to the modern PowerPact H-frame series. Sourcing this exact legacy breaker is ideal for direct replacements in existing panels, as it eliminates the need for retrofit hardware.
