Product FAQs

6 answers
What is the difference between the Eaton GD3100 and GHB3100?

Both are 100-amp, 3-pole, Series C G-frame breakers, but they feature different mounting styles. The GD3100 is a unit-mount (feed-thru) breaker with cable-in and cable-out lugs, whereas the GHB3100 is a bolt-on breaker designed for direct bus connection in Eaton panelboards.

What types of equipment are compatible with the GD3100?

As a unit-mount breaker, it is designed for use in Eaton Series C panelboards, motor control centers, switchboards, and standalone enclosures that support feed-thru configurations.

Can I field-install internal accessories in the GD3100?

No. Eaton Series C G-frame circuit breakers are factory-sealed. Field installation of internal accessories, such as shunt trips or auxiliary switches, will void the UL listing. These components must be factory-installed.

What wire sizes do the standard lugs on the GD3100 accept?

The included lugs are designed to accommodate wire gauges ranging from 14 AWG up to 1/0 AWG.

Is the GD3100 suitable for reverse feed applications?

Yes, this thermal-magnetic molded case circuit breaker is suitable for reverse feed installations.

Can the GD3100 be used in DC electrical systems?

Yes. While commonly used in 240VAC and 480VAC systems, this breaker is also rated for 125/250VDC applications with a 10kA interrupting capacity.
