Description
Built for commercial and industrial facilities, the Eaton G2090 is a 2-pole, 90A molded case circuit breaker designed for legacy systems. It mounts securely into older Westinghouse and Cutler-Hammer panelboards or motor control centers, ensuring safe and continuous operation. This G-frame breaker serves as a direct hardware match for obsolete 600V applications where modern GHB or GD series replacements fall short. It features a 10kAIC rating at 600VAC, reverse feed capability, and HACR rating.Specifications

Product FAQs
6 answersWhich panelboards accept the Westinghouse G2090 circuit breaker?
This G-frame breaker is designed to mount directly into legacy Westinghouse panelboards and motor control centers. It is a direct fit for these older systems without requiring the modern F-frame adapter kits that newer replacement breakers often need.
Are Eaton and Westinghouse G2090 breakers interchangeable?
Yes. Eaton acquired the Westinghouse electrical distribution division, so G-frame breakers may carry Eaton, Cutler-Hammer, or Westinghouse branding. They share the exact same physical dimensions and electrical characteristics.
What type of protection does the LI trip function provide?
The LI designation indicates the breaker is equipped with fixed thermal (Long-Time) and fixed magnetic (Instantaneous) trip elements. This delivers reliable protection against both sustained overloads and sudden short circuits without requiring manual trip adjustments.
Can the G2090 be utilized in direct current applications?
Yes, this thermal-magnetic breaker is rated for both alternating current and direct current systems. It provides a 14kA interrupting capacity at 250VDC, making it suitable for industrial DC control circuits.
Why use a bolt-on breaker like the G2090 in a motor control center?
Bolt-on connections provide a highly secure, vibration-resistant contact with the busbar. This is critical in industrial motor control centers where heavy machinery and constant vibration can loosen standard plug-on connections over time.
What is the acceptable wire size range for the G2090 terminals?
The factory-installed lugs accommodate wire sizes from 10 AWG up to 1/0 AWG. Ensure proper torque specifications are followed during installation to maintain a secure electrical connection.
