Product FAQs
5 answersAre Eaton and Cutler-Hammer GD3060 breakers interchangeable?
Yes, they are the exact same product. Eaton acquired Cutler-Hammer, and the Series C product line remains identical. A GD3060 with an Eaton label is a direct drop-in replacement for an older Cutler-Hammer branded unit.
Can the GD3060 be back-fed in a panel?
Yes, this breaker is rated as suitable for reverse feed use. This allows line power to be connected to either the upper or lower terminals, which is frequently required when utilizing the breaker as a main disconnect.
How does a unit-mount breaker like the GD3060 install?
Unit-mount breakers are designed to be individually fastened to a backpan, mounting plate, or DIN rail adapter within an enclosure. They wire via their cable-in and cable-out lugs rather than bolting or plugging directly onto a panelboard busbar.
What does the LI designation mean for this breaker's trip unit?
The LI code indicates a thermal-magnetic trip unit. It provides fixed Long-Time (L) thermal protection against continuous overcurrents and fixed Instantaneous (I) magnetic protection to clear short circuits rapidly.
Is this Series C breaker suitable for direct current (DC) applications?
Yes, the GD3060 carries a DC rating for systems up to 250VDC with a 10kA interrupting capacity. When applying it to DC loads, follow NEC multi-pole wiring guidelines to ensure safe operation and proper arc extinguishing.
