Product FAQs
6 answersWhat does the U31X suffix indicate on the HJL36060U31X?
The U31X suffix specifies that the breaker is equipped with a Micrologic 3.2 electronic trip unit. This provides adjustable long-time and fixed instantaneous (LI) protection, offering more precise trip coordination than standard thermal-magnetic models.
Can the HJL36060U31X be installed in a Square D I-Line panelboard?
No. This specific model is a unit-mount breaker, meaning it has feed-thru lugs on both the line and load sides. It is designed for industrial control panels, enclosures, and switchboards, rather than plug-on I-Line panelboards.
What are the wire gauge limits for the factory lugs on this 60A breaker?
The standard lugs on the HJL36060U31X accept aluminum or copper conductors ranging from 14 AWG up to 3/0 AWG. Ensure proper torque specifications are followed during installation as outlined by Schneider Electric.
Is the HJL36060U31X a direct physical replacement for older PowerPacT H-frame breakers?
Yes, it shares the exact physical dimensions and mounting footprint as other unit-mount PowerPacT H-frame breakers. When upgrading from a thermal-magnetic model, verify that the Micrologic 3.2 electronic trip unit meets your specific coordination requirements.
Does the HJL36060U31X support internal field-installable accessories?
Yes, the PowerPacT H-frame design allows for field-installable internal accessories such as shunt trips, auxiliary switches, and undervoltage releases. These are mounted inside the accessory compartment behind the front cover.
Does the Micrologic 3.2 trip unit require an external power supply for basic protection?
No, the Micrologic 3.2 electronic trip unit is self-powered by the current flowing through the breaker. It does not require an external power source to perform its primary long-time and instantaneous tripping functions.
