Product FAQs
6 answersCan the GHC3050 be mounted on a standard DIN rail?
Yes, this unit mount breaker can be installed on a 35mm DIN rail, but it requires a specific Eaton DIN rail adapter plate for proper mounting.
What types of enclosures and panels accept the GHC3050 breaker?
This G-frame breaker is designed for use in Eaton Series C enclosures, motor control centers, and various OEM control panels that support unit-mounted, feed-thru configurations.
Is the GHC3050 suitable for use in DC circuits?
Yes, it is rated for DC applications up to 125/250VDC with an interrupting capacity of 14kAIC, making it suitable for specific industrial control and battery systems.
How does the thermal-magnetic trip unit operate on the GHC3050?
