Product FAQs
5 answersWhat does the U44X suffix mean in the HGL36100U44X catalog number?
The U44X suffix indicates that the breaker is equipped with a Micrologic 6.2 A electronic trip unit. This specific trip unit provides adjustable LSIG (Long-Time, Short-Time, Instantaneous, and Ground-Fault) protection and includes an integrated ammeter for current monitoring.
Is the HGL36100U44X compatible with Square D I-Line panelboards?
No. This is a unit-mount, feed-thru circuit breaker designed for lug-to-lug connections. It does not have the plug-on jaw connections required for I-Line panelboards. It is intended for industrial control panels, switchboards, and standard PowerPacT H-Frame enclosures.
What are the wire size requirements for the lugs on this breaker?
The factory lugs on the HGL36100U44X accept wire sizes from 14 AWG to 3/0 AWG. The terminals are rated for both aluminum and copper conductors.
Does the HGL36100U44X provide equipment ground-fault protection?
Yes. The included Micrologic 6.2 A trip unit features an adjustable ground-fault trip function (the G in LSIG) to protect electrical equipment from damaging ground-fault currents.
Can the trip settings on the HGL36100U44X be adjusted in the field?
Yes. The Micrologic electronic trip unit allows electricians to adjust the Long-Time, Short-Time, Instantaneous, and Ground-Fault pickup and delay settings to coordinate with specific system requirements.
