Product FAQs
6 answersCan I install the JJA36150 in a standard Square D NF or NQ panelboard?
No. The JJA36150 features an I-Line plug-in mounting design. It is strictly compatible with Square D I-Line panelboards and switchboards, and will not fit in NQ or NF series panels.
How are the line and load connections configured on this I-Line breaker?
The line side utilizes I-Line plug-in jaws that engage directly onto the panelboard bus. The load side is equipped with mechanical lugs that accept 4 AWG to 4/0 AWG aluminum or copper conductors for the outgoing circuit.
What does the JJA prefix signify in the PowerPacT series?
In the Square D PowerPacT J-Frame family, the JJA prefix designates the interrupting rating tier. Specifically, it indicates a 65kA interrupting rating at 480VAC.
Are the trip unit settings adjustable on the JJA36150?
It features a thermal-magnetic trip unit with a fixed thermal element for long-time overload protection and an adjustable magnetic dial. This allows you to configure the instantaneous short-circuit pickup threshold to suit your application.
Does this circuit breaker provide ground-fault or arc-fault protection?
No. This is a standard thermal-magnetic molded case circuit breaker designed for overcurrent and short-circuit protection. It does not contain GFCI or AFCI sensing electronics.
Which legacy circuit breakers can the JJA36150 replace?
This modern PowerPacT J-Frame breaker often serves as a direct replacement or upgrade for obsolete Square D 150A I-Line breakers, including the legacy KC36150, KH36150, and KA36150 models.
