Description
Built for commercial power systems, the KAL36070 is a 3-pole, 70A molded case circuit breaker. It provides essential long-time and instantaneous (LI) protection for demanding networks. The unit-mount design allows installation into Square D switchboards and motor control centers. For modern replacements, this legacy K-Frame transitions to the PowerPacT H-Frame (HGL36070). It delivers a 25 kAIC rating at 480VAC and includes an adjustable magnetic trip for precise coordination.Specifications

Product FAQs
7 answersWhat is the modern replacement for the legacy Square D KAL36070?
The KAL36070 is part of the legacy Square D K-Frame family. For modern upgrades, it is typically replaced by a 70A Square D PowerPacT H-Frame unit-mount breaker. Note that retrofitting a PowerPacT breaker into an older enclosure may require a different mounting pan or hardware adaptations.
Which replacement lug kit is compatible with this K-Frame breaker?
The Square D AL250KA mechanical lug kit is the direct replacement for KAL, KHL, KCL, and KIL frame circuit breakers. It includes three lugs rated for 4 AWG to 350 kcmil wire.
What wire sizes are compatible with the standard lugs on the KAL36070?
The standard line and load lugs on this breaker accept 4 AWG to 350 kcmil aluminum or copper (Al/Cu) conductors.
How does the LI trip unit function on this breaker?
The "LI" designation means this thermal-magnetic breaker provides Long-Time (L) and Instantaneous (I) protection. The long-time thermal element is fixed for standard overload protection, while the instantaneous magnetic element is adjustable for short-circuit protection.
Is the KAL36070 rated for use in DC electrical systems?
Yes, in addition to its AC ratings, this breaker is rated for DC applications up to 250VDC, delivering a 10kAIC interrupting rating at that voltage.
How does the mounting style of the KAL36070 differ from KA-frame breakers?
The KAL36070 is a unit-mount (feed-thru) breaker designed to be bolted directly to a backpan or enclosure. In contrast, KA-frame breakers feature a plug-on design specifically for Square D I-Line panelboards.
Where is this unit-mount breaker typically installed?
It is designed for installation in compatible Square D enclosures, switchboards, and motor control centers that accommodate legacy unit-mount K-Frame breakers.
