Description
Built for commercial environments, the Square D IF36100 is a 3-pole, 100A molded case circuit breaker from the I-Limiter family. It operates at up to 600VAC with thermal-magnetic trip technology. The I-Line plug-on mounting style allows for quick installation into compatible Square D panelboards. It serves as the predecessor to the HRA36100 replacement model. With a 200kAIC rating at 480VAC, its current-limiting design reduces let-through energy to protect downstream components.Specifications

Product FAQs
5 answersWhat panelboards are compatible with the IF36100 circuit breaker?
This breaker is designed exclusively for Square D I-Line panelboards and switchboards. It utilizes an I-Line plug-on mounting connection and will not fit in standard residential load centers like QO or Homeline.
What does the Current Limiting designation mean for the IF36100?
As part of the Square D I-Limiter family, this breaker is engineered to clear faults in a fraction of a cycle. This rapid response significantly reduces the peak let-through current and energy during a short circuit, providing enhanced protection for downstream electrical components.
Is the Square D IF36100 still manufactured, or is there a direct replacement?
The IF-frame series is obsolete and no longer in active production. It is typically replaced by the newer Square D PowerPact H-frame series, such as the HRA36100, which provides the same 100A capacity, 200kAIC rating at 480V, and I-Line mounting style.
How much bus mounting space does this 3-pole breaker require in an I-Line panelboard?
The IF36100 requires 4.5 inches of mounting space on the panelboard bus, which is standard for 3-pole F-frame and IF-frame I-Line circuit breakers up to 250A.
How does the thermal-magnetic trip unit function on this breaker?
The IF36100 features fixed long-time (L) and instantaneous (I) trip functions. The thermal bimetal element safely clears sustained overloads that develop over time, while the magnetic element trips the breaker instantly in the event of a severe short circuit.
