Product FAQs
5 answersWhat type of panelboards accept the MGA268002 circuit breaker?
This breaker is designed exclusively for Square D I-Line panelboards and switchboards. It will not fit in standard QO, NQ, or NF load centers.
How does the I-Line connection work on this breaker?
The MGA268002 features an I-Line style plug-on connection for the line side, which snaps directly onto the panelboard bus. The load side uses mechanical lugs for wire termination.
Can the MGA268002 replace older legacy M-frame breakers?
Yes, the PowerPacT M-frame series is the direct replacement for older Square D legacy M-frame breakers, such as the MA, ME, MH, and MX series, when used in I-Line panels.
Does the MGA268002 have an adjustable trip setting?
Yes, while the thermal rating is fixed at 800 amps, the ET 1.0 electronic trip unit features an adjustable magnetic trip setting for instantaneous short-circuit protection.
Can this 2-pole breaker be installed in a 3-phase I-Line panelboard?
Yes, 2-pole I-Line breakers are commonly installed in 3-phase panelboards to supply single-phase loads. The plug-on jaws will connect to two of the three bus phases.
