Enclosed Circuit Breakers

Eaton's enclosed circuit breakers offer all the advantages and accessories of a circuit breaker packaged in an enclosure for nearly any application requiring a means of disconnect. In addition, we also have two specialty solutions available to further enhance safety that come fully wired: Arcflash Reduction Maintenance System (ARMS) technology and 30 mA ground fault protection. Enclosed circuit breakers with ARMS technology can improve safety by providing a simple and reliable method to reduce fault clearing time. These specialty circuit breakers are fully factory wired and allow a customer to activate ARMS technology during maintenance. This can help reduce required personal protection equipment levels, which improves worker comfort, mobility and productivity. Our 30 mA ground fault protection, also known as Marina Ground Fault enclosed breaker, offers 30 mA ground fault protection for marinas and boat yards. The shunt trip inside the enclosed breaker can be adjusted to change as load demands change, offering flexibility on the job site.

For our enclosed circuit breakers, please go to the resources tab to get more information or view the ARMS product aid or the 30 mA product aid.
