Description
Engineered for remote operation, the FIL36070-1021 includes a factory-installed 120-240VAC shunt trip alongside its standard thermal-magnetic protection. This 3-pole, 70A current limiting MCCB mounts into Square D enclosures, switchboards, and panelboards. It provides robust fault protection with a 200 kAIC rating at 480VAC, effectively limiting let-through energy to safeguard downstream industrial equipment. For modern replacements, the HRL36070 can be used with an S29386 shunt trip accessory.Specifications

Product FAQs
5 answersWhat does the -1021 suffix indicate on the FIL36070-1021 part number?
The -1021 suffix designates that this circuit breaker includes a factory-installed 120/240VAC shunt trip. This accessory allows the breaker to be tripped remotely by applying a voltage signal to the shunt trip coil.
What is the difference between the FIL36070-1021 and a standard FAL36070-1021?
The FIL series is the current-limiting version of the Square D F-frame breaker, offering significantly higher interrupting ratings (up to 200kA at 480VAC) compared to the standard FAL series. Both share the same physical dimensions and unit-mount configurations.
How does the current-limiting design affect this breaker's performance?
The current-limiting FIL frame restricts the peak let-through current and clearing time during a fault. This minimizes thermal and mechanical stress on downstream electrical components and enables the breaker to safely interrupt severe short circuits.
Can this 600V-rated breaker be applied to 480V or 240V systems?
Yes, the FIL36070-1021 can be safely applied to lower voltage AC systems. When used on 480VAC or 240VAC systems, the interrupting capacity increases to 200kA, compared to its 100kA rating at 600VAC.
How does the thermal-magnetic trip unit operate on this 70A breaker?
The Long-Time and Instantaneous (LI) trip unit provides dual-level protection. The thermal bimetal element responds to sustained overloads with an inverse-time delay, while the magnetic electromagnetic assembly trips the breaker instantaneously when high-level short circuits are detected.
