Description
Part of the I-Limiter series, the Square D IF36030 is a 3-pole, 30A molded case circuit breaker built for commercial power distribution. It provides thermal-magnetic protection with long-time and instantaneous trip functions. This unit features a plug-on connection, allowing for rapid installation into compatible Square D I-Line panelboards. It serves as the legacy predecessor to the PowerPact HRA36030. Rated at 200 kAIC at 480VAC, its current-limiting design minimizes let-through current.Specifications

Product FAQs
8 answersWhat panelboards are compatible with the IF36030?
This breaker is designed exclusively for Square D I-Line panelboards and switchboards. It features a plug-on jaw connection that mounts directly to the I-Line bus stack.
What does the current limiting feature of the IF36030 do?
As part of the Square D I-Limiter family, this breaker clears faults in under a half-cycle. This rapid response significantly reduces peak let-through current and energy, providing enhanced protection for sensitive downstream equipment.
How does the I-Line mounting system work during installation?
The IF36030 utilizes a plug-on jaw connection on the line side that snaps directly onto the panelboard bus. The load side uses standard mechanical lugs for wire termination, allowing for fast and secure installation.
What is the modern replacement for the legacy IF36030?
The IF-frame is a legacy series. The direct modern equivalent is the PowerPact H-frame series, specifically catalog number HRA36030, which matches the 30A, 3-pole, I-Line mounting, and 200kAIC at 480VAC specifications.
What type of protection does the LI trip unit provide?
The breaker features a thermal-magnetic trip unit with fixed Long-Time (L) and Instantaneous (I) functions. The thermal element protects against sustained overloads, while the magnetic element provides immediate tripping during short circuits.
What wire sizes are accepted by the load lugs?
The standard mechanical lugs accept 14 to 4 AWG copper (Cu) conductors or 12 to 4 AWG aluminum (Al) conductors. Always ensure proper torque specifications are met during termination.
Can the IF36030 be used on 480V industrial systems?
Yes, the breaker is rated for a maximum of 600VAC. When applied to 480VAC systems, it provides a high interrupting rating of 200kAIC, making it suitable for heavy commercial and industrial applications.
Are the trip settings adjustable on the IF36030?
No, this breaker features a fixed thermal and fixed magnetic trip unit. The Long-Time and Instantaneous trip thresholds are factory set and cannot be adjusted in the field.
