Description
Part of the Square D I-Limiter series, the IF34100 is a 3-pole, 100A molded case circuit breaker engineered for commercial and industrial applications. It features thermal-magnetic trip technology to protect downstream equipment from overloads and short circuits. This breaker mounts into Square D I-Line panelboards, utilizing a plug-on connection for rapid installation. For modern upgrades, this legacy IF-frame unit is replaced by the HRA36100. It delivers a robust 200kAIC rating at 480VAC.Specifications

Product FAQs
7 answersWhat panelboards accept the Square D IF34100 circuit breaker?
The IF34100 is designed specifically for installation in Square D I-Line panelboards and switchboards. It features an I-Line style plug-in connection that mounts directly to the bus assembly.
What wire sizes are compatible with the terminal lugs on the IF34100?
The breaker accepts 14 to 1/0 AWG copper (Cu) conductors or 12 to 1/0 AWG aluminum (Al) conductors.
What does the LI trip function indicate on this I-Limiter breaker?
The LI designation means the thermal magnetic trip unit provides Long-Time (L) protection for sustained overloads and Instantaneous (I) protection for short circuits. Both the thermal and magnetic trip points are fixed and cannot be adjusted in the field.
Is the IF34100 a current-limiting circuit breaker?
Yes, the IF34100 is part of the Square D I-Limiter family. It is engineered to clear high-level fault currents rapidly, reducing the let-through energy to protect downstream electrical components.
What is the modern replacement for the legacy IF34100 breaker?
The IF34100 is a discontinued IF-frame breaker. For modern upgrades, it is commonly replaced by the Square D PowerPact H-frame series, such as the HRA36100, depending on the specific interrupting capacity required for your application.
How is the IF34100 installed into an I-Line panelboard?
The breaker utilizes a plug-on mounting design. The line-side jaws engage directly with the panelboard bus stack, which eliminates the need for individual line-side wire connections and speeds up the installation process.
What applications require the 200kAIC rating of the IF34100?
The 200kA interrupting capacity at 480V makes this breaker suitable for commercial and industrial facilities with high available fault currents, ensuring the breaker can safely clear severe short circuits without sustaining catastrophic damage.
