Designed for robust equipment protection, this 30A molded case circuit breaker integrates thermal-magnetic trip technology with a ground fault module for commercial systems. This three-pole breaker fits into Square D I-Line panelboards. When crossing over to the newer HRA36030 replacement, ensure the new unit is configured with equivalent ground fault protection. Delivering 200kAIC at 480V, the current-limiting breaker includes a Visi-Trip indicator to quickly identify tripped circuits.

Product FAQs
7 answers
What type of panelboard is the IF36030G compatible with?
This breaker is designed exclusively for Square D I-Line panelboards and switchboards. It uses a plug-on jaw connection to attach directly to the I-Line busbar system.
What does the G suffix in the IF36030G catalog number indicate?
The G indicates that this breaker includes Ground Fault Equipment Protection (GFEP). It is designed to protect equipment from damaging ground faults, typically tripping at a 30mA threshold, rather than the 5mA threshold used for personnel protection.
Is the IF36030G a current-limiting circuit breaker?
Yes, the IF frame is part of the Square D I-Limiter series. It is a current-limiting breaker designed to actively restrict let-through energy during a fault, which minimizes stress on downstream components and provides a high 200kA interrupting rating at 480VAC.
How does the IF36030G mount into the electrical panel?
It features an I-Line mounting style. The line side uses plug-on jaws that press onto the panelboard busbars, while the load side uses standard mechanical lugs for wire connections.
Is the IF36030G still in active production?
The IF frame is a legacy Square D F-frame breaker. For modern facility upgrades, the IF series has been replaced by the PowerPact H-frame series, though IF breakers are still sourced for maintaining existing I-Line panels.
Can I use the IF36030G for personnel ground fault protection?
No. This breaker provides Ground Fault Equipment Protection (GFEP) to prevent equipment damage. It does not provide the 5mA Class A ground fault protection (GFCI) required for personnel safety.
Are the thermal and magnetic trip settings adjustable on the IF36030G?
No, this breaker features fixed thermal and fixed magnetic trip settings. It does not offer field-adjustable trip dials for the long-time or instantaneous functions.
