Product FAQs

6 answers
What panelboards are compatible with the KH36100 circuit breaker?

This breaker is designed exclusively for use in Square D I-Line panelboards and switchboards. It features an I-Line style plug-in connection on the line side.

How does the I-Line mounting style work on this breaker?

The I-Line design uses a plug-on connection for the line side that attaches directly to the panelboard bus. The load side uses standard mechanical lugs for wire termination.

What wire sizes do the lugs on the KH36100 accept?

The factory lugs accept aluminum or copper wire ranging from 4 AWG to 350 kcmil.

What does the LI trip function mean on this breaker?

The LI designation indicates it has a thermal magnetic trip unit providing Long-Time and Instantaneous protection. The thermal element is fixed, while the magnetic instantaneous trip is adjustable to tune the short-circuit response.

Can the KH36100 be used in DC power systems?

Yes, in addition to its AC ratings, this breaker is rated for 250VDC systems with an interrupting capacity of 10kAIC.

Is the Square D KH36100 still in active production?

The KH36100 is a legacy K-Frame breaker. For new installations or modern upgrades, the manufacturer recommends crossing this over to a newer PowerPact series breaker, such as the JJA36100, depending on your specific panel requirements.
