Product FAQs
7 answersWhat does the U31X suffix indicate in the HJA36060U31X part number?
The U31X designation means this breaker is equipped with a MicroLogic 3.2 solid-state electronic trip unit. This provides adjustable Long-Time and Instantaneous (LI) protection, which offers more precise coordination than traditional thermal-magnetic trip units.
Which panelboards accept the HJA36060U31X circuit breaker?
This PowerPacT H-Frame breaker features an I-Line plug-in mounting configuration. It is designed to install directly into Square D I-Line power distribution panelboards and switchboards, including the HCW, HCN, HCP, and HCM series enclosures.
Can the HJA36060U31X replace legacy Square D F-Frame I-Line breakers?
Yes, PowerPacT H-Frame I-Line breakers are backward compatible with older Square D I-Line switchboards and panelboards. They are frequently used to replace older F-Frame models, such as FA or FH breakers, provided the voltage and interrupting capacity meet your current system requirements.
Are the trip unit settings on this 60A breaker field adjustable?
Yes. The MicroLogic 3.2 electronic trip unit features adjustable dials on the face of the breaker for both Long-Time pickup and Instantaneous pickup, allowing electricians to fine-tune the protection curve to the specific load.
Does the HJA36060U31X require bolted connections to attach to the panel bus?
No. The I-Line mounting style uses integral blow-on type line-side connectors that snap securely onto the panelboard bus stack without requiring bolted hardware or mounting screws. The load side utilizes standard mechanical lugs for wire termination.
What conductor materials are compatible with the lugs on this breaker?
The factory-installed mechanical lugs (typically part number AL150HD) are dual-rated for both copper (Cu) and aluminum (Al) conductors, accepting wire sizes from 14 AWG to 3/0 AWG.
What is the purpose of the push-to-trip button on the front cover?
The integral push-to-trip button allows qualified personnel to manually trip the operating mechanism. This verifies that the internal mechanical linkages are functioning properly and is recommended as part of routine preventative maintenance.
