Product FAQs
6 answersWhat wire size and torque are required for the lugs on the MGL36700?
The standard mechanical lugs accept three 3/0 AWG to 500 kcmil aluminum or copper conductors per phase. The wire binding screws must be torqued to 442.5 lb-in (50 N.m).
Can I adjust the trip settings on the MGL36700?
The MGL36700 features a basic ET 1.0 electronic trip unit with fixed long-time protection and adjustable instantaneous protection. The instantaneous pickup can typically be adjusted from 2 to 10 times the nominal rating, but the long-time trip point cannot be field adjusted.
Can the PowerPacT MGL36700 be reverse fed?
Yes, PowerPacT M-frame electronic trip circuit breakers can be reverse connected without restrictive line and load markings.
What is the difference between the MGL36700 and the MGA36700?
The MGL36700 is a unit-mount, feed-thru circuit breaker with mechanical lugs on both the line and load sides. The MGA36700 is the I-Line plug-on version designed specifically for Square D I-Line panelboards and switchboards.
What equipment is the MGL36700 compatible with?
This unit-mount breaker is designed for use in Square D switchboards, motor control centers, and individual enclosures that accept PowerPacT M-frame devices.
What does the G in the MGL36700 part number indicate?
