Engineered for industrial applications, this 70A thermal-magnetic device provides reliable long-time and instantaneous (LI) protection. It installs into compatible Square D switchboards, motor control centers, and industrial control panels. For modern upgrades, this legacy component is replaced by the PowerPact H-Frame HGL26070 using a retrofit kit. Delivering 42kAIC at 240VAC, it includes a Visi-Trip indicator and an adjustable magnetic trip mechanism to fine-tune short-circuit response.

Product FAQs
7 answers
What types of panels and enclosures are compatible with the KAL26070?
This K-frame breaker is designed for use in Square D enclosures, switchboards, motor control centers, and industrial control panels that accept unit-mount breakers.
How is the KAL26070 circuit breaker mounted?
It features a unit-mount, feed-thru design. It bolts directly to the backpan or mounting surface rather than plugging onto a busbar like I-Line variants.
What wire sizes are accepted by the lugs on this breaker?
The included line and load lugs accept 4 AWG to 350 kcmil aluminum or copper wire.
Can the KAL26070 be used in DC electrical systems?
Yes, in addition to its AC ratings, this thermal-magnetic breaker is rated for up to 250VDC with a 10kA interrupting capacity.
What does the LI trip function code indicate on this breaker?
The LI designation stands for Long-Time and Instantaneous trip functions. It features a fixed thermal element for long-time overload protection and an adjustable magnetic element for instantaneous short-circuit protection.
Is the Square D KAL series still in active production, or is there a modern replacement?
The KAL series is a legacy K-frame breaker. For modern upgrades or replacements, Square D typically recommends the PowerPact H-frame series, though exact cross-referencing depends on your specific panel and AIC requirements.
What safety precautions should be taken before installing or servicing this breaker?
Always de-energize the switchboard or panel before installation. Verify that power is off using a properly rated voltage sensing device, and ensure the breaker voltage and AIC ratings meet or exceed the available fault current of your system.
