Description
Engineered for industrial applications, the Square D KAL361251380 is a 3-pole, 125A molded case circuit breaker. It delivers reliable thermal-magnetic protection for heavy-duty electrical systems and motor control centers. This unit-mount breaker installs into standard Square D enclosures. As a legacy K-Frame component, it is replaced by the modern PowerPacT J-Frame (JGL36125) for system upgrades. Rated 25kA at 480VAC, this model includes a 120VAC shunt trip and 1A/1B auxiliary switch.Specifications

Product FAQs
6 answersWhat does the 1380 suffix indicate on the KAL361251380?
The 1380 suffix designates a factory-installed 120VAC shunt trip and a 1A/1B auxiliary switch. This configuration allows for remote tripping of the breaker and provides remote status signaling.
How is the KAL361251380 installed in a power system?
This is a unit-mount, feed-thru circuit breaker. It bolts directly to the backpan of compatible Square D enclosures, switchboards, or motor control centers, and requires wire connections at both the line and load lugs. It is not compatible with I-Line plug-on panelboards.
Can the trip settings on the KAL361251380 be adjusted?
The thermal-magnetic trip unit features a fixed thermal element for long-time overload protection and an adjustable magnetic element for instantaneous short-circuit protection.
Is the KAL361251380 suitable for DC voltage systems?
Yes, in addition to its standard AC ratings, this breaker is rated for 250VDC applications with a 10kA interrupting capacity.
What type of wire can be used with the standard lugs on this breaker?
The factory lugs are rated for both aluminum and copper conductors, accepting wire sizes from 4 AWG up to 350 kcmil.
What protection is provided by the LI trip functions?
The LI code indicates that the breaker provides Long-Time (L) protection against sustained overloads and Instantaneous (I) protection to immediately clear severe short circuits.
