Product FAQs

5 answers
What is the difference between Eaton GHC and GHB circuit breakers?

While both are Series C G-frame breakers, GHC breakers like the GHC3045 are cable-in/cable-out unit mount breakers designed for enclosures and OEM panels. GHB breakers are bolt-on breakers designed specifically for Eaton panelboards.

Can the GHC3045 be mounted on a DIN rail?

Yes, although it is a surface-mounted breaker by default, it can be installed on a standard DIN rail by using a compatible Eaton DIN rail adapter.

What wire sizes are accepted by the GHC3045 terminals?

The standard lugs on this breaker accept wire gauges from 10 AWG up to 1/0 AWG.

What does the 480Y/277VAC slash rating indicate for system compatibility?

A slash rating means the breaker is only approved for use on solidly grounded wye systems where the line-to-ground voltage does not exceed 277V and the line-to-line voltage does not exceed 480V. It is not suitable for ungrounded or corner-grounded delta systems.

Are the trip settings on the GHC3045 adjustable?

No, this breaker uses a thermal-magnetic trip unit with fixed thermal and fixed magnetic settings. The long-time and instantaneous trip functions cannot be adjusted in the field.
