Product FAQs
7 answersWhat panelboards and equipment are compatible with the EGC3050FFG circuit breaker?
This EG-frame breaker is designed for use in Eaton Series G panelboards, Pow-R-Line panelboards, switchboards, and motor control centers.
What does the FFG suffix in the EGC3050FFG catalog number indicate?
The FFG suffix indicates that the breaker comes as a complete unit with a fixed thermal and fixed magnetic trip unit, and includes both line and load terminals.
What wire sizes are accepted by the terminals on this 50A breaker?
The included line and load box terminals accept wire ranging from 14 AWG to 1/0 AWG. Ensure proper torque specifications are followed during installation.
Is the EGC3050FFG suitable for DC voltage applications?
Yes, in addition to its AC ratings, this thermal-magnetic breaker is rated for use in DC systems up to 125/250 VDC, providing an interrupting capacity of 42 kAIC.
What type of protection does the LI trip unit provide in this breaker?
The thermal-magnetic trip unit features fixed long-time (L) and instantaneous (I) functions. The long-time function protects against sustained overloads, while the instantaneous function provides immediate tripping during short circuits.
Is the EGC3050FFG a direct replacement for Cutler-Hammer breakers with the same part number?
Yes, Eaton acquired Cutler-Hammer, and this Series G breaker is a direct, authentic replacement for older Cutler-Hammer EGC3050FFG models.
What does the 600Y/347 VAC voltage rating signify for the EGC3050FFG?
This slash rating indicates the breaker is approved for use in solidly grounded wye electrical systems where the line-to-line voltage is up to 600 VAC and the line-to-ground voltage does not exceed 347 VAC. It is not suitable for 600V ungrounded delta systems.
