Product FAQs

8 answers
What are the instantaneous trip settings for the MGL36800?

The ET 1.0 basic electronic trip unit on this breaker features a fixed long-time trip and an adjustable instantaneous trip range from 1200 A to 6000 A.

Is the Square D MGL36800 100 percent rated for continuous current?

No, this circuit breaker carries a standard 80 percent continuous current rating.

What type of lug terminations are standard on the MGL36800?

This unit-mount circuit breaker comes standard with mechanical box lugs on both the line and load ends, accepting three 3/0 AWG to 500 kcmil aluminum or copper conductors per phase.

What kind of trip unit does the MGL36800 feature?

It utilizes a factory-sealed basic electronic trip system (Type ET 1.0) with long-time and instantaneous (LI) protection. Electronic trip units provide more precise tripping and are less sensitive to ambient temperature changes than traditional thermal-magnetic models.

Does this breaker support field-installable electrical accessories?

Yes, PowerPacT M-Frame circuit breakers share internal electrical accessories, such as auxiliary switches, alarm switches, shunt trips, and undervoltage releases, with PowerPacT P-Frame devices.

What safety standards and certifications apply to this breaker?

The MGL36800 is UL Listed, CSA Certified, NOM Certified, IEC Rated, and carries the CE mark for global acceptance.

What is the difference between the MGL36800 and MJL36800?

The MJL36800 is the higher interrupting capacity version. While the MGL36800 provides 35kA at 480VAC, the MJL36800 delivers up to 65kA at 480VAC. Both breakers share the same 800A capacity, physical frame dimensions, and ET 1.0 electronic trip unit.

Can this breaker be installed directly onto an I-Line bus?

No, the MGL36800 is a unit-mount circuit breaker equipped with mechanical lugs on both ends. For an I-Line panelboard or switchboard, you must source the I-Line version of the PowerPacT M-Frame breaker, which features a plug-on jaw connection on the line side.
