Product FAQs
8 answersWhat equipment is the MGF36600 circuit breaker designed to fit?
This unit mount breaker is engineered for installation in Square D switchboards and motor control centers. It requires a bolt-on connection and is not compatible with I-Line panelboards.
What type of trip unit is installed in the MGF36600?
It includes a basic ET 1.0 electronic trip unit. This provides fixed long-time and adjustable instantaneous (LI) protection. The trip unit is factory installed and cannot be replaced or upgraded in the field.
What does the G in the MGF36600 catalog number indicate?
The G specifies the interrupting rating tier for this PowerPacT M-Frame breaker. It delivers a maximum interrupting capacity of 65 kA at 240VAC, 35 kA at 480VAC, and 18 kA at 600VAC.
How does the MGF36600 differ from the MGA36600?
The MGF36600 is a unit mount breaker designed for bolt-on connections in switchboards and motor control centers. The MGA36600 is the I-Line variant, which features a plug-on design specifically for Square D I-Line panelboards.
Can the MGF36600 be mounted horizontally or vertically?
Yes, PowerPacT M-Frame unit mount circuit breakers can be mounted and operated in any position without affecting their tripping characteristics or performance.
Does the MGF36600 provide ground fault protection?
No. The included ET 1.0 trip unit only offers long-time and instantaneous (LI) protection. It does not have the equipment ground fault sensing capabilities found in LSIG trip units.
Does the MGF36600 come with mechanical lugs?
No, the F in the catalog number indicates it is configured for busbar connections and does not include lugs. If you field-install standard mechanical lugs, they will accept three 3/0 AWG to 500 kcmil aluminum or copper conductors per phase.
How can I manually test the mechanical operation of the MGF36600?
You can use the integral push-to-trip button located on the front cover. Pressing this button manually trips the breaker, allowing you to verify the mechanical operation of the tripping mechanism before maintenance.
