Product FAQs

6 answers
What specific trip unit is included with the LGL36600U44X?

This breaker is equipped with a Micrologic 6.3A electronic trip unit. The U44X suffix indicates it provides Long-Time, Short-Time, Instantaneous, and Ground Fault (LSIG) protection, plus an integrated ammeter for current monitoring.

How is the LGL36600U44X installed in an enclosure?

This is a unit-mount circuit breaker. It bolts directly to the backpan or mounting plate of a switchboard, panelboard, or standalone PowerPacT L-Frame enclosure, using feed-thru lug connections on both the line and load sides.

Can I install this breaker in a Square D I-Line panelboard?

No. The LGL36600U44X is a unit-mount breaker and does not have the plug-on jaws required for I-Line bus connections. You must use an I-Line specific L-Frame breaker for those panelboards.

What are the conductor size limits for the factory lugs on this 600A breaker?

The standard mechanical lugs accept two 2/0 AWG to 500 kcmil conductors per phase. They are rated for both aluminum and copper wire.

Does the Micrologic 6.3A trip unit support Zone Selective Interlocking (ZSI)?

Yes, the Micrologic 6.3A trip unit features ZSI capability. When wired correctly with compatible upstream and downstream breakers, it allows the system to isolate faults faster while maintaining selective coordination.

Are the LSIG protection bands adjustable on this model?

Yes. The electronic trip unit allows precise adjustments for the pickup and time delay settings across all four protection bands (Long-Time, Short-Time, Instantaneous, and Ground Fault) to meet specific coordination studies.
