Product FAQs
6 answersWhat does the 6139 suffix mean on the KAL361256139 catalog number?
The 6139 suffix indicates that the breaker includes a factory-installed 120-240VAC shunt trip. This accessory allows the breaker to be opened remotely via a control signal for emergency shutdown or interlock applications.
What is the modern replacement for the legacy KAL361256139 breaker?
Square D legacy K-Frame breakers are typically replaced by the PowerPacT H-Frame series, such as the HGL36125, for 125A applications. You will need to add a compatible 120-240VAC shunt trip accessory to the H-Frame to match the functionality of the 6139 suffix, and panel modifications may be required.
Is the trip unit on the KAL361256139 fully adjustable?
No, the thermal-magnetic trip unit features a fixed thermal element for long-time (L) overload protection and an adjustable magnetic element for instantaneous (I) short-circuit protection.
What wire sizes are compatible with the lugs on this breaker?
The factory-installed line and load lugs accept wire gauges from 4 AWG up to 350 kcmil. The terminals are rated for both aluminum and copper conductors.
Can the KAL361256139 be used in direct current (DC) systems?
Yes, it is rated for use in DC systems up to 250VDC, where it provides an interrupting rating of 10kA.
Where is the KAL361256139 typically installed?
This unit-mount, feed-thru breaker is designed for installation in legacy Square D enclosures, switchboards, and motor control centers that accommodate K-Frame dimensions.
