What does the -1021 suffix mean on the Square D KAL36175-1021?

The -1021 suffix indicates that this circuit breaker includes a factory-installed 120/240VAC shunt trip for remote tripping applications.

What is the modern replacement for the legacy Square D KAL36175-1021?

The KAL series is a legacy K-Frame breaker. The modern equivalent is the PowerPact J-Frame series, such as the JGL36175. Upgrading to a PowerPact breaker requires a separate shunt trip accessory and may require a retrofit kit depending on your enclosure.

What wire sizes are accepted by the lugs on the KAL36175-1021?

The factory lugs on this K-Frame breaker accept 4 AWG to 350 kcmil aluminum or copper wire.

Is the trip unit on the KAL36175-1021 adjustable?

This breaker features a thermal magnetic trip unit with a fixed thermal element for long-time protection and an adjustable magnetic element for instantaneous short-circuit protection.

What does the LI trip function code mean on this breaker?

The LI designation indicates that the thermal magnetic trip unit provides Long-Time (L) overload protection and Instantaneous (I) short-circuit protection.

What types of equipment is the KAL36175-1021 compatible with?

This unit-mount breaker is designed for use in compatible Square D enclosures, switchboards, motor control centers, and industrial control panels.

How is the KAL36175-1021 mounted in a panel?

This is a unit-mount, or feed-thru, circuit breaker. It is secured using mounting hardware rather than plugging in or bolting onto a busbar like I-Line breakers.
