Product FAQs
6 answersWhat frame size is the Eaton GHC1050?
The GHC1050 is part of the Eaton Series C G-frame family of molded case circuit breakers. This compact frame size is commonly used in industrial control panels and OEM equipment.
How is the Eaton GHC1050 installed in an electrical system?
Unlike panelboard-specific breakers, the GHC1050 utilizes a feed-thru (cable-in/cable-out) connection. This allows it to be surface-mounted in standalone enclosures, control panels, or adapted for DIN rail installations rather than bolting directly to a busbar.
What is the difference between Eaton GHC and GHB circuit breakers?
While both are Series C G-frame breakers with identical trip profiles, their mounting methods differ. The GHC1050 is a feed-thru breaker designed for cable connections or DIN rail mounting, whereas GHB breakers are bolt-on units specifically designed for Eaton Pow-R-Line panelboards.
How does the thermal-magnetic trip unit in the GHC1050 operate?
The breaker features a fixed thermal-magnetic trip unit. The thermal component provides a long-time delay to safely handle temporary overloads, while the magnetic component delivers an instantaneous trip response to clear severe short circuits immediately.
Is the GHC1050 compatible with external rotary handles?
Yes, as a standard G-frame breaker, it is compatible with Eaton's direct-acting rotary handle mechanisms (such as the HRGCC3S) and other external operating handles used in NEMA-rated industrial enclosures.
What makes the GHC1050 suitable for direct current (DC) systems?
Beyond standard AC distribution, this breaker is certified for use in 125VDC systems. This dual AC/DC capability allows it to be deployed in specialized industrial control circuits, battery backups, and transit applications requiring reliable DC overcurrent protection.
