Product FAQs
8 answersWhat does the 1021 suffix indicate on the KAL361101021 catalog number?
The 1021 suffix means this breaker comes equipped with a factory-installed 120/240VAC shunt trip, allowing the breaker to be tripped remotely by an external voltage signal.
What is the difference between the KAL36110 and the KAL361101021?
The KAL36110 is the standard base model K-Frame breaker. The KAL361101021 is the exact same 110A breaker but includes the factory-installed 120/240VAC shunt trip accessory.
Is the magnetic trip setting adjustable on this 110A breaker?
Yes, while the thermal (long-time) protection is fixed at 110 amps, the magnetic (instantaneous) trip setting is adjustable to help coordinate with other protective devices in your electrical system.
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) protection for overloads and Instantaneous (I) protection for short circuits.
What type of wire can be used with the factory lugs on the KAL361101021?
The included lugs are rated for both aluminum and copper (Al/Cu) conductors, accepting wire sizes from 4 AWG up to 350 kcmil.
Can this K-Frame breaker be used in DC applications?
Yes, the KAL361101021 is rated for 250VDC systems and provides up to 10kA interrupting capacity for direct current applications.
Can I install the KAL361101021 in a Square D I-Line panelboard?
No, this is a unit-mount (feed-thru) breaker designed for individual enclosures, switchboards, and control panels. It does not have the plug-on jaw connections required for I-Line panelboards.
How do I safely test the mechanical operation of this breaker?
You can use the push-to-trip feature to manually trip the breaker. This verifies the mechanical linkage is operating correctly without requiring exposure to live electrical parts.
