Product FAQs
6 answersWhat is the modern replacement for the KAL36110-1039?
The legacy K-Frame KAL36110-1039 is replaced by the Square D PowerPacT HGL36110. Because the -1039 suffix indicates a 12VDC shunt trip, you will need to add a compatible 12VDC shunt trip accessory to the new H-Frame breaker to maintain remote tripping functionality.
What does the -1039 suffix indicate on this KAL breaker?
The -1039 suffix designates a factory-installed 12VDC shunt trip. This allows the circuit breaker to be tripped remotely by applying a 12VDC control voltage signal, which is commonly used for emergency stops or automated load shedding.
How is the KAL36110-1039 installed in a system?
This is a unit-mount, feed-thru circuit breaker. It bolts directly to the backpan of legacy Square D enclosures, switchboards, or motor control centers, rather than plugging into an I-Line bus.
How does the adjustable magnetic trip work on this 110A breaker?
While the thermal overload protection is fixed at 110A, the magnetic instantaneous trip is adjustable. This allows panel builders to fine-tune the short-circuit response to coordinate with downstream devices and prevent nuisance tripping from motor inrush currents.
Can I install this K-Frame breaker in an I-Line panelboard?
No, the KAL36110-1039 is a unit-mount breaker designed for individual enclosures or backpan mounting. For an I-Line panelboard, you would need an I-Line specific breaker, such as the legacy KA or modern PowerPacT HGA series.
Is the KAL36110-1039 suitable for DC applications?
Yes, this thermal-magnetic breaker is rated for use in DC systems up to 250VDC, where it provides an interrupting capacity of 10kA. It can be utilized in battery-string or charger feeder applications, provided the system voltage does not exceed 250VDC.
