Description
Serving commercial and industrial facilities, the Square D KH36080 is an 80A, 3-pole molded case circuit breaker. It utilizes thermal-magnetic trip technology to safeguard electrical circuits against overloads and short circuits. This legacy K-frame breaker mounts into Square D I-Line panelboards and switchboards. For modern upgrades, it is replaced by the HJA36080 model. It features a 35kA interrupting rating at 480VAC and includes load side lugs for secure connections.Specifications

Product FAQs
7 answersIs the Square D KH36080 still manufactured, or is there a modern replacement?
The KH36080 is a legacy K-frame breaker. For modern upgrades, Square D recommends replacing it with the PowerPact H-frame series, specifically the HJA36080 model, which fits the same I-Line panelboards and switchboards.
What is the magnetic trip range for the KH36080?
This breaker features a fixed thermal and adjustable magnetic trip. The magnetic trip settings range from a 400A hold to an 800A trip.
What size wire do the standard lugs on the KH36080 accept?
The factory-installed mechanical lugs (catalog number AL250KA) accept one 4 AWG to 350 kcmil aluminum or copper conductor per phase.
What does the H in the KH36080 catalog number indicate?
In Square D legacy K-frame nomenclature, the H designates a High Interrupting capacity. This provides a 35kAIC rating at 480VAC, which is a step up from standard KA-frame breakers.
What type of panels is the KH36080 compatible with?
This breaker features an I-Line style plug-in connection on the line side, making it compatible exclusively with Square D I-Line panelboards and switchboards. It cannot be used in standard QO load centers or unit-mount applications.
Can I use a KH36080 to replace a KA36080?
Yes. The KH36080 shares the exact same physical K-frame footprint and I-Line mounting as the KA36080, but it offers a higher interrupting capacity. It is a direct, safe upgrade for a KA36080 in existing I-Line panels.
Can the KH36080 be used in DC applications?
Yes, the KH36080 is rated for use on direct current systems up to 250VDC, where it provides a 10kA interrupting rating.
