Product FAQs
5 answersWhat is the modern replacement for the legacy Square D KAL36150-1021?
The legacy K-Frame breakers have been superseded by the Square D PowerPact J-Frame series. However, the KAL36150-1021 remains a direct fit for existing K-Frame setups without requiring panel modifications.
What does the -1021 suffix indicate on this breaker?
The -1021 suffix signifies that the breaker includes a factory-installed 120VAC shunt trip accessory. This allows the breaker to be tripped remotely by applying a 120V control voltage signal, which is commonly used for emergency stops or automated safety shutdowns.
Can the KAL36150-1021 be installed in an I-Line busway system?
No, this is a unit-mount (feed-thru) breaker designed for lug-to-lug connections. For I-Line busway installations, an I-Line specific breaker, such as the KCA or JJA series, is required.
How does the Push-to-Trip feature work on this breaker?
Square D K-Frame breakers include a Push-to-Trip button that allows you to manually trip the breaker. This verifies the mechanical operation of the tripping mechanism without exposing personnel to live parts.
Is the KAL36150-1021 compatible with modern Square D enclosures?
Yes, this K-Frame breaker mounts into compatible Square D enclosures, switchboards, and motor control centers that are designed to accept legacy K-Frame unit-mount breakers.
