Description
The KAL36250-1027 is a 3-pole, 250A molded case circuit breaker from Square D's legacy K-Frame series. Built for industrial power distribution, it delivers reliable long-time and instantaneous (LI) thermal-magnetic protection. It installs into standard Square D enclosures, switchboards, and motor control centers. For modern upgrades, this unit is replaced by the PowerPacT J-Frame (JGL36250). This model features a factory-installed 24VDC shunt trip and a 42kAIC rating at 240VAC.Specifications

Product FAQs
5 answersWhat does the -1027 suffix indicate on the KAL36250-1027?
The -1027 suffix means this breaker comes with a factory-installed 24VDC shunt trip. This allows the breaker to be tripped remotely via a 24VDC control signal, which is commonly used for emergency stops or automated control systems.
Can the KAL36250-1027 be installed in an I-Line panelboard?
No. The KAL36250-1027 is a unit-mount breaker designed to bolt directly to a backplate or mounting pan. For I-Line plug-on applications, you need the KA36250 variant instead.
How many conductors can be terminated on each lug of the KAL36250-1027?
The standard line and load lugs are designed to accept a single conductor per phase, accommodating wire sizes from 4 AWG to 350 kcmil in either copper or aluminum.
How do I adjust the trip settings on the KAL36250-1027?
The thermal overload protection (long-time) is fixed at 250A and cannot be changed. However, the magnetic (instantaneous) trip is adjustable via a dial on the front of the breaker, allowing you to coordinate the short-circuit response with other devices in your system.
What is the modern replacement for the legacy KAL36250-1027?
The Square D K-Frame series has been superseded by the PowerPact J-Frame series. If you are upgrading a panel, a 250A PowerPact J-Frame breaker with a 24VDC shunt trip is the modern equivalent, though mounting dimensions and footprint will differ.
