Product FAQs

8 answers
What equipment is compatible with the EGB2050FFG breaker?

This EG-frame breaker is designed for use in Eaton Series G enclosures, switchboards, motor control centers, and custom OEM panels requiring unit-mount configurations.

What wire types and sizes are accepted by the EGB2050FFG terminals?

The standard line and load lugs accept 14 AWG to 1/0 AWG copper or aluminum (Cu/Al) conductors. Always torque connections to the manufacturer's specifications during installation.

What does the LI trip function on this breaker indicate?

The LI designation means the breaker features a thermal-magnetic trip unit with Long-Time (L) and Instantaneous (I) protection. The Long-Time function protects against sustained overloads, while the Instantaneous function trips immediately during a short circuit.

Is the EGB2050FFG rated for direct current (DC) applications?

Yes, this breaker is rated for up to 250VDC with an interrupting capacity of 10kAIC, making it suitable for specific DC control panels and distribution systems.

Does the EGB2050FFG offer current-limiting capabilities?

Yes, Eaton Series G EG-frame breakers utilize a patented high-speed blow-open contact design that provides current-limiting performance, reducing the let-through energy during a short circuit.

Can the EGB2050FFG replace older Cutler-Hammer breakers?

Yes, Eaton Series G breakers are physically and electrically interchangeable with many classic Westinghouse and Cutler-Hammer molded case circuit breakers, making them ideal for retrofitting existing panelboards and motor control centers.

Can the EGB2050FFG be reverse fed?

Yes, this thermal-magnetic EG-frame breaker is suitable for reverse feed applications, allowing power to be supplied to either the line or load terminals without affecting its protective functions.

How is the EGB2050FFG mounted in a panel?

This is a unit-mount breaker, meaning it is secured using mounting screws directly to the panel backpan or mounting plate, rather than snapping onto a DIN rail or plugging into a busbar.
