Description
Built for demanding commercial applications, the Square D KIL362258041 is a 3-pole, 225A molded case circuit breaker. As a current-limiting device, it reduces let-through fault currents to safeguard downstream components. This unit-mount breaker installs into Square D enclosures and switchboards. It serves as a replacement for older K-Frame installations, with the JRL36225 acting as a modern substitute. Rated 200kAIC at 480VAC, it features factory-installed control wire taps.Specifications

Product FAQs
6 answersIs the Square D KIL362258041 still in active production?
No, the K-frame series is a legacy molded case circuit breaker and is no longer manufactured. For new installations, it has been superseded by the Square D PowerPact J-frame series, such as the JRL36225.
What does the 8041 suffix mean on the KIL362258041 catalog number?
The 8041 suffix indicates that the circuit breaker comes equipped with factory-installed control wire tap lugs. These tapped lugs are designed to accept small 22-14 AWG wire for control circuit connections.
Is the KIL362258041 compatible with Square D I-Line panelboards?
No, the KIL362258041 is a unit-mount circuit breaker designed for feed-thru applications. It does not have the plug-on jaw connections required for I-Line panelboards.
What equipment is the KIL362258041 designed to be installed in?
This unit-mount breaker is compatible with legacy Square D enclosures, switchboards, and motor control centers designed to accept K-frame circuit breakers.
How does the adjustable magnetic trip work on the KIL362258041?
The thermal-magnetic trip unit features a fixed thermal element for long-time overload protection and an adjustable magnetic element, allowing electricians to set the instantaneous short-circuit trip threshold based on the specific application.
How does the current-limiting feature of the KIL362258041 protect electrical systems?
As a current-limiting breaker, it is designed to clear severe short circuits extremely fast. This limits the peak let-through current and energy, reducing thermal and mechanical stress on downstream equipment.
