Product FAQs
8 answersDoes the HJA36080 replace older legacy Square D breakers?
Yes, the PowerPacT H-frame HJA36080 serves as a direct, modern replacement for discontinued Square D F-frame I-Line circuit breakers of the same amperage, including the FA36080, FH36080, and FC36080.
Does the HJA36080 require a separate mounting kit for installation?
No. As an I-Line style breaker, the HJA36080 features integrated plug-on jaws on the line side that connect directly to the panelboard busbar, along with a built-in mounting bracket for secure retention.
Can field-installable accessories be added to this breaker?
Yes, the HJA36080 accepts a variety of internal field-installable accessories that mount behind the front cover, including shunt trips, undervoltage releases, and auxiliary or alarm switches.
What is the magnetic trip range for the HJA36080?
The HJA36080 is equipped with a non-interchangeable fixed thermal-magnetic trip unit that features a magnetic hold current of 800A and a magnetic trip current of 1450A.
What is the default phase connection for this circuit breaker?
The default phase connection for the 3-pole HJA36080 is ABC. This aligns with standard phase arrangements in 3-phase I-Line panelboards and switchboards.
What replacement lug kit is compatible with the load side of the HJA36080?
The standard load-side mechanical lug kit for 15A to 150A PowerPacT H-frame breakers is the AL150HD.
Is the HJA36080 recognized as a current-limiting circuit breaker?
Yes. The HJA36080 is a current-limiting circuit breaker, designed to significantly reduce the peak let-through current and clear high-magnitude faults very quickly.
Is this I-Line breaker suitable for reverse-feed applications?
No. Because it is an I-Line plug-on circuit breaker designed specifically for busbar connections on the line side, the HJA36080 cannot be reverse fed. Only standard unit-mount PowerPacT H-frame breakers are rated for reverse connection.
