Built for demanding industrial environments, the Square D FIL36030 is a 3-pole, 30A current-limiting circuit breaker. It utilizes thermal-magnetic trip technology to deliver exceptional 200kAIC protection at 480VAC, safeguarding downstream equipment from high fault currents. This F-Frame MCCB features a unit-mount configuration for integration into Square D switchboards and individual enclosures. For modern panelboard upgrades, this legacy breaker is replaced by the HRL36030.

Product FAQs
7 answers
What types of enclosures or panels accept the FIL36030 breaker?
The FIL36030 is a unit-mount F-frame breaker designed for use in Square D switchboards, motor control centers, and individual enclosures. It is not compatible with I-Line panelboards.
What wire sizes and materials are compatible with the lugs on the FIL36030?
The factory-installed line and load lugs accept 14 AWG to 4 AWG copper or aluminum conductors.
What does the current-limiting designation mean for the FIL36030?
As a current-limiting breaker, the FIL36030 clears faults extremely fast, reducing the let-through energy and peak current during a short circuit. This helps protect downstream equipment from severe thermal and mechanical stress.
Can I install the FIL36030 in a Square D I-Line panelboard?
No. The FIL36030 is a unit-mount breaker with line and load lugs. It does not have the plug-on jaw required for I-Line bus systems.
What type of trip unit is installed in the FIL36030?
This breaker features a non-interchangeable thermal-magnetic trip unit with fixed long-time and fixed instantaneous trip functions.
How is the FIL36030 physically mounted?
The FIL36030 is a unit-mount breaker that bolts directly to a mounting pan or enclosure backplate. It does not plug onto a busbar system.
Can the FIL36030 be used in IEC applications?
Yes, the FIL36030 carries CE approval and is rated for use on 415VAC systems with a 6kA interrupting capacity under IEC standards.
