Description
Built for demanding commercial environments, the Square D KHL36100 is a 3-pole, 100-amp molded case circuit breaker. It utilizes fixed thermal and adjustable magnetic trip elements to deliver precise LI protection for heavy-duty electrical networks. Designed for unit mounting, this device integrates seamlessly into Square D enclosures and switchboards. For facilities updating their infrastructure, this legacy K-Frame model transitions to the newer PowerPacT H-Frame (HGL36100).Specifications

Product FAQs
8 answersWhat type of enclosures and panels are compatible with the KHL36100?
This unit-mount breaker is designed for use in compatible Square D enclosures, switchboards, and motor control centers. It is not compatible with I-Line panelboards, which require plug-on I-Line breakers.
What wire sizes do the standard lugs on the KHL36100 accept?
The standard lugs accept aluminum or copper wire ranging from 4 AWG to 350 kcmil.
How does the adjustable magnetic trip function work on this breaker?
The KHL36100 features a thermal-magnetic trip unit with a fixed thermal element for overload protection at 100A and an adjustable magnetic element. The adjustable magnetic setting allows you to fine-tune the instantaneous short-circuit trip threshold to suit your specific application.
What does the H in the KHL frame designation indicate?
The H indicates that this is a high-interrupting capacity breaker within the legacy Square D K-Frame family. It provides a 35kA interrupting rating at 480VAC and 65kA at 240VAC, which is higher than standard KAL or KDL frame breakers.
Is the KHL36100 suitable for direct current (DC) applications?
Yes, in addition to its AC ratings, this breaker is rated for use in DC systems up to 250VDC, where it provides a 10kA interrupting rating.
Is the KHL36100 an I-Line circuit breaker?
No, the KHL36100 is a unit-mount, feed-thru circuit breaker. If you need a plug-on breaker for an I-Line panelboard, you will need an I-Line specific K-Frame breaker.
What is the modern replacement series for the legacy KHL36100?
The KHL36100 is a legacy K-Frame breaker. For new installations or modern upgrades, Square D has transitioned to the PowerPact series, where the H-Frame or J-Frame typically serves as the modern equivalent depending on your panel requirements.
Is the KHL36100 HACR rated?
Yes, this breaker is HACR rated, meaning it is approved for use with heating, air conditioning, and refrigeration equipment.
