Product FAQs
6 answersWhat type of lugs are included with the MGL26800 circuit breaker?
The MGL26800 comes standard with AL800M23K mechanical lugs on both the line and load sides. These lugs accept three 3/0 AWG to 500 kcmil aluminum or copper conductors per phase.
What does the G in the MGL26800 catalog number signify?
The G indicates the interrupting rating tier for this PowerPacT M-frame breaker. It provides a maximum interrupting capacity of 65kA at 240VAC, 35kA at 480VAC, and 18kA at 600VAC.
Can the Square D MGL26800 be reverse fed?
Yes. PowerPacT M-frame circuit breakers with the ET 1.0 electronic trip unit can be reverse connected. They do not have restrictive line and load markings, allowing them to be bottom fed.
What type of trip unit is installed in the MGL26800?
This breaker features a factory-sealed ET 1.0 basic electronic trip unit. It provides fixed Long-Time (L) protection and adjustable Instantaneous (I) protection, which can be set from 2 to 10 times the nominal ampere rating.
How does the MGL26800 mount into an electrical system?
The MGL26800 is a unit-mount, feed-thru circuit breaker. It bolts directly to the backpan or mounting surface of Square D switchboards, motor control centers, or individual enclosures, unlike I-Line plug-on variants.
Does the MGL26800 provide ground fault protection?
No. The MGL26800 is equipped with an LI (Long-Time, Instantaneous) trip unit. It does not offer equipment ground fault protection.
