Product FAQs

6 answers
Which panelboards are compatible with the LXIL36100?

This breaker is designed exclusively for Square D I-Line panelboards and switchboards. It features a plug-on line side connection that engages directly with the I-Line bus stack.

What are the acceptable wire sizes for the load side lugs on this breaker?

The standard load lugs accept either one 1 AWG to 600 kcmil aluminum or copper conductor, or two 1 AWG to 250 kcmil aluminum or copper conductors per phase.

How does the LSI electronic trip unit function on this L-Frame breaker?

The LSI designation indicates adjustable Long-time, Short-time, and Instantaneous trip bands. This allows panel builders to fine-tune the time-current curve for precise selective coordination with downstream devices.

What does the X in the LXIL prefix indicate?

The X denotes an extra-high interrupting capacity. This specific frame provides up to 200kAIC at 480VAC, making it suitable for industrial applications with extremely high available fault currents.

Does this breaker require a separate mounting bracket for I-Line panels?

No. I-Line breakers feature built-in mounting jaws that clamp directly onto the panelboard bus assembly, requiring only a screwdriver to secure the retaining bracket to the deadfront.

Is the LXIL36100 part of the current Square D catalog?

This is a legacy L-Frame molded case circuit breaker. While still widely used and supported in existing I-Line installations, new panel designs typically utilize the modern PowerPact L-Frame series.
