Product FAQs

7 answers
What equipment is the KAL26100 compatible with?

This unit-mount breaker is designed for use in legacy Square D switchboards, motor control centers, and individual enclosures that accept K-Frame breakers.

What is the standard lug kit for the KAL26100?

The standard mechanical lug kit is the AL250KA, which accepts 4 AWG to 350 kcmil aluminum or copper wire.

How does the trip unit on the KAL26100 operate?

It features a thermal-magnetic trip unit with a fixed thermal element for overload protection and an adjustable magnetic element, allowing you to set the instantaneous short-circuit trip threshold.

Is the Square D KAL26100 still in active production?

The KAL series is a legacy K-Frame breaker. While exact replacements depend on your panel mounting hardware, Square D officially transitioned this series to the modern PowerPact H-Frame and J-Frame families.

Can the KAL26100 be reverse fed?

Yes, standard thermal-magnetic KAL breakers can be back-fed because they are not marked with line and load restrictions. However, if equipped with a ground-fault module, reverse feeding is not permitted.

Can this breaker be used in DC applications?

Yes, the KAL26100 is rated for up to 250VDC with a 10kA interrupting capacity, making it suitable for specific direct current systems.

What does the feed-thru connection type mean for installation?

A feed-thru, or unit-mount, configuration means the breaker bolts directly to the mounting surface or enclosure backpan rather than plugging into a busbar. Both the line and load sides require wired lug connections.
