Product FAQs
9 answersWhat panelboards accept the MGA36800SA breaker?
It is engineered specifically for Square D I-Line panelboards and switchboards. The I-Line design uses a unique plug-on bus connection that eliminates the need for line-side cabling, allowing for faster and safer installation in compatible enclosures.
What does the SA suffix in the MGA36800SA catalog number indicate?
The SA suffix means this breaker includes a factory-installed shunt trip accessory. This specific shunt trip operates on a 110 to 130V AC or 125V DC control voltage, allowing the breaker to be tripped remotely by an external signal.
How is the line side of this breaker connected in the panel?
The MGA36800SA utilizes an I-Line style plug-in connection on the line side. This allows the breaker to mount directly onto the I-Line bus stack without bolted line-side cables, while the load side uses standard mechanical lugs.
What type of trip unit is installed in the MGA36800SA?
This breaker features a solid state electronic trip unit equipped with adjustable long time and instantaneous (LI) trip functions. This allows for precise coordination and overcurrent protection tailored to your specific load requirements.
What are the acceptable wire sizes for the load side lugs on this 800A breaker?
The factory-installed load side lugs accept three aluminum or copper conductors per phase, ranging from 3/0 AWG to 500 kcmil. Ensure proper torque specifications are followed during termination to prevent overheating.
Does the MGA36800SA provide equipment ground fault protection?
No. This specific model includes only long time and instantaneous (LI) trip functions. If ground fault protection is required for your application, you will need a breaker equipped with an LSIG trip unit configuration.
Can I use this breaker to replace a standard MGA36800?
Yes. The MGA36800SA shares the exact same physical dimensions, mounting, and electrical ratings as the standard MGA36800. The only difference is the included 110 to 130V AC shunt trip. If your system does not require a shunt trip, you can simply leave the accessory control wires disconnected.
What is the proper procedure for testing the shunt trip on this breaker?
To test the shunt trip, apply the rated control voltage (110 to 130V AC or 125V DC) to the accessory leads while the breaker is in the closed (ON) position. The breaker should immediately trip, and the handle will move to the center tripped position.
Is this breaker suitable for reverse feeding?
No. Because it features an I-Line plug-in connection on the line side, it is designed for a specific directional power flow from the I-Line bus and cannot be reverse fed.
