Engineered for industrial applications, the Square D KAL36225-1021 is a 3-pole, 225A molded case circuit breaker from the legacy K-Frame family. This unit-mount breaker installs into Square D enclosures, switchboards, and motor control centers. It serves as an exact replacement for existing KAL installations, though it is officially replaced by the JGL36225. Rated for 42kAIC at 240VAC, this MCCB includes a factory-installed 120-240VAC shunt trip and a Visi-Trip indicator.Specifications

Product FAQs
6 answersWhat does the -1021 suffix indicate on the KAL36225-1021?
The -1021 suffix designates that this breaker comes with a factory-installed 120-240VAC shunt trip, allowing the breaker to be opened remotely via a control signal.
What is the direct modern replacement for the legacy KAL36225-1021?
The Square D PowerPact J-Frame JGL36225 is the modern equivalent. However, because the J-Frame has different dimensions, upgrading requires a retrofit kit, and the shunt trip must be ordered as a separate field-installable accessory.
Can I install the KAL36225-1021 in an I-Line panelboard?
No, the KAL36225-1021 is a unit-mount, feed-thru breaker designed for standard enclosures, switchboards, and motor control centers. For an I-Line plug-on connection, you would need the KA36225-1021 equivalent.
How does the trip adjustability work on this K-Frame breaker?
The KAL36225-1021 features a thermal-magnetic trip unit with a fixed thermal element for continuous overload protection at 225A, and an adjustable magnetic element that allows electricians to fine-tune the instantaneous short-circuit response.
Can the shunt trip on the KAL36225-1021 be removed or swapped in the field?
No, the 120-240VAC shunt trip indicated by the -1021 suffix is factory-installed inside the breaker housing and is not designed to be field-replaceable or modified.
How can I tell if the KAL36225-1021 has tripped?
When the breaker trips due to an overcurrent, short circuit, or a remote shunt trip signal, the handle moves to a center position to clearly indicate the tripped status.
