Eaton has over 50 patents in technology related to arc fault detection and circuit interruption and has UL certified devices in production.

This patented Arc-AlertT Circuit Interrupter is a new type of circuit protection device that recognizes the unique characteristics of many types of arcing faults associated with Aerospace wiring faults and acts instantly to interrupt the circuit.

115VAC 400hz Hz arc fault circuit breaker is availible in a size to fit most traditional circuit breaker installations. Eaton's Aerospace AFCI Circuit breakers have been undergoing flight testing since April 2001 and are a ready solution to common electrical defects not detected by traditional circuit breakers.

Eaton is adapting the technology to 28 VDC aerospace applications and demonstrating the technology and soliciting input from key aerospace users and standards organizations.
