Product FAQs
6 answersWhat equipment is the GWF3020 circuit breaker designed to fit?
It is compatible with Eaton and Cutler-Hammer Series C panelboards, switchboards, and motor control centers.
Does the GWF3020 snap into the panel bus?
No, this is a unit-mount, bolt-on circuit breaker. It must be bolted directly to the chassis or buswork rather than snapping into place, ensuring a secure feed-thru connection.

Yes, it comes standard with factory-installed line and load lugs designed to accept 14 AWG to 1 AWG wire.
What does the LI trip function code mean for the GWF3020?
The LI designation indicates that the breaker provides Long-Time (thermal) protection against overloads and Instantaneous (magnetic) protection against short circuits, ensuring comprehensive safety for the connected circuit.
