Product FAQs
6 answersWhat does the 8041 suffix indicate on the KAL361258041 catalog number?
The 8041 suffix designates that this breaker includes factory-installed control wire tapped lugs. This feature allows electricians to easily connect control circuits directly at the breaker terminals.
What is the modern replacement for the legacy Square D KAL361258041?
Square D has superseded the legacy K-Frame series with the PowerPact H-Frame for 125A applications. However, using the original KAL361258041 ensures an exact fit for existing enclosures and switchboards without the need for retrofit kits or modifications.
How does the trip unit function on this breaker?
The KAL361258041 features a thermal-magnetic trip unit with a fixed thermal element for long-time overload protection and an adjustable magnetic element. The adjustable magnetic trip allows panel builders to fine-tune the instantaneous short-circuit response based on the specific load.
Can this breaker be installed in direct current (DC) systems?
Yes, while it is primarily used in AC systems up to 600VAC, this breaker is also rated for 250VDC applications, providing 10kA of interrupting capacity for DC infrastructure.
What does unit mount mean for the KAL361258041?
As a unit mount breaker, it is designed to be bolted directly to the mounting pan or backplate of compatible Square D enclosures, switchboards, and motor control centers, rather than plugging onto a busbar system like I-Line breakers.
Is this breaker physically interchangeable with other K-Frame models?
Yes, as part of the Square D K-Frame family, it shares the same physical dimensions and mounting footprint as other KAL, KHL, and KCL breakers. This makes it a direct drop-in replacement for existing 3-pole K-Frame units.
