Product FAQs
6 answersWhat does the -1039 suffix mean on the KAL36150-1039 circuit breaker?
The -1039 suffix indicates that this breaker includes a factory-installed 12VDC shunt trip accessory, allowing the breaker to be tripped remotely.
What is the modern replacement for the legacy Square D KAL36150-1039?
The legacy K-Frame series has been replaced by the Square D PowerPact J-Frame series. A functional equivalent is a 150A, 3-pole PowerPact J-Frame breaker (such as the JJL36150) equipped with a 12VDC shunt trip accessory.
How does the KAL36150-1039 mount into an electrical panel?
This is a unit mount circuit breaker. It secures directly to the backpan or mounting surface of compatible Square D enclosures, switchboards, and motor control centers using screws, rather than plugging onto a busbar.
What type of wire can be used with the KAL36150-1039 lugs?
The factory lugs on this breaker are rated for both aluminum and copper conductors, accepting wire sizes from 4 AWG up to 350 kcmil.
Can I adjust the trip settings on the KAL36150-1039?
This thermal magnetic breaker features a fixed thermal element for long-time overload protection and an adjustable magnetic element for instantaneous short-circuit protection.
How is the shunt trip wired on the KAL36150-1039?
The factory-installed 12VDC shunt trip includes control wire leads that exit the breaker housing. These leads must be connected to a 12VDC control power source and a remote normally open switch or relay to activate the trip mechanism.
