Description
Providing reliable circuit protection, the Square D KHL36090 is a 3-pole, 90A molded case circuit breaker. This K-Frame device safeguards electrical infrastructure against severe overcurrents. Designed for feed-thru applications, the unit-mount breaker connects via standard lugs within Square D switchboards. For system upgrades, engineers can replace this unit with the PowerPacT J-Frame (JJL36090). With 65kAIC at 240VAC, the thermal-magnetic trip mechanism provides LI functions.Specifications

Product FAQs
8 answersWhat enclosures and panels are compatible with the KHL36090?
This unit-mount breaker is designed for installation in Square D enclosures, switchboards, and motor control centers.
Is the KHL36090 compatible with I-Line panelboards?
No, the KHL36090 is a unit-mount, feed-thru breaker designed to be bolted in place and connected via lugs. It does not have the plug-on jaw connections required for I-Line panelboards.
What wire sizes are supported by the standard lugs on this breaker?
The factory lugs accept 4 AWG to 350 kcmil aluminum or copper (Al/Cu) conductors.
How are the trip settings adjusted on the KHL36090?
This breaker features a thermal-magnetic trip unit with a fixed thermal element for long-time overload protection and an adjustable magnetic dial for instantaneous short-circuit protection.
What is the difference between the KHL36090 and the KAL36090?
The KHL36090 is the high-interrupting version of the standard KAL36090. It offers a higher interrupting capacity, rated at 35kA at 480V compared to the 25kA at 480V rating of the standard KAL frame.
What does the LI trip function code mean on this breaker?
The LI designation indicates that the breaker provides Long-Time (L) protection against overloads and Instantaneous (I) protection against short circuits.
What is the modern replacement for the legacy KHL36090?
The KHL36090 is a legacy K-frame breaker. For new installations or system upgrades, it is typically replaced by the modern Square D PowerPacT H-frame series, though mounting hardware and dimensions will differ.
Does the KHL36090 provide ground fault protection?
No, this breaker is equipped with a standard thermal-magnetic trip unit providing long-time and instantaneous (LI) protection only. It does not include integral equipment ground fault protection.
