Product FAQs
6 answersWhat does the -1021 suffix mean on the KAL36110-1021?
The -1021 suffix indicates that this breaker includes a factory-installed 120/240VAC shunt trip. This accessory allows the circuit breaker to be tripped remotely by applying a voltage signal to the shunt trip coil.
Is the KAL36110-1021 still manufactured, or is there a modern replacement?
The KAL36110-1021 is a legacy K-Frame breaker. For modern panel upgrades, it is typically replaced by the Square D PowerPact H-Frame series. A common direct cross-reference with a 120VAC shunt trip is the HDL36110SA, though you should verify that its interrupting ratings meet your specific system requirements.
Can I install the KAL36110-1021 in an I-Line panelboard?
No. The KAL36110-1021 is a unit-mount, feed-thru circuit breaker designed to be bolted to the backplate of Square D enclosures, switchboards, and motor control centers. For an I-Line plug-on connection, you would need a KA-frame breaker, such as the KA36110.
What does the LI trip function code mean on this breaker?
The LI trip function code indicates that the breaker provides Long-Time (L) and Instantaneous (I) protection. The long-time function protects against sustained overloads, while the instantaneous function provides immediate tripping during short-circuit faults.
Is the trip unit on the KAL36110-1021 adjustable?
The KAL36110-1021 features a thermal-magnetic trip unit with a fixed thermal (overload) setting and an adjustable magnetic (short-circuit) setting, allowing you to fine-tune the instantaneous trip response to your specific load requirements.
Does this breaker include a Push-to-Trip feature?
Yes, the KAL36110-1021 features a Push-to-Trip button on the face of the breaker. This allows you to manually trip the breaker to verify the mechanical operation of the trip mechanism without exposing yourself to live parts.
