Product FAQs
8 answersWhat equipment is the Square D MGP26600 circuit breaker compatible with?
The MGP26600 is designed for use in Square D QED Switchboards, Model 6 Motor Control Centers, and as a main breaker in I-Line Panelboards (including HCP, HCN, and HCM models).
What type of mounting does the MGP26600 use?
This PowerPacT M-frame breaker features a unit mount (bolt-on) design, meaning it comes with lugs on both the line and load sides for direct wire connections rather than plugging into an I-Line bussing system.
What wire sizes are accepted by the lugs on the MGP26600?
The factory-installed lugs accept three 3/0 AWG to 500 kcmil aluminum or copper wires per phase.
What type of trip unit is installed in the MGP26600?
It is equipped with a basic ET 1.0 electronic trip unit providing Long-Time and Instantaneous (LI) protection. It functions as an electronic equivalent of a thermal-magnetic breaker, featuring fixed thermal (long-time) and adjustable magnetic (instantaneous) settings.
What does the G in the MGP26600 catalog number signify?
The G indicates the breaker's interrupting capacity tier within the PowerPacT M-frame series, which provides 65kA at 240V, 35kA at 480V, and 18kA at 600V.
Is the MGP26600 a 100% rated circuit breaker?
No, the MGP26600 is a standard 80% rated circuit breaker.
Does the MGP26600 include a push-to-trip feature?
Yes, like all Square D PowerPacT circuit breakers, it includes an integral push-to-trip button on the front cover that allows you to manually trip the breaker to verify the mechanical operation of the tripping mechanism.
Is the MGP26600 an I-Line breaker?
No, the P in the MGP26600 catalog number indicates it is a unit-mount breaker with lugs on both ends. The I-Line equivalent for plug-on panelboard applications is the MGA26600.
