Make safety a priority with authentic breakers

Molded case circuit breakers are critical to safeguarding people and property. Consistent with our commitment to safety, Eaton strives to help you make well-informed sourcing decisions and avoid unnecessary risks. Eaton does not verify product from non-authorized resellers as being factory direct, and therefore Eaton does not warranty product purchased from these sources. Only an authorized Eaton distributor can provide the Power Of Authenticity.
