Power Defense Series circuit breakers are Eaton-brand molded case circuit breakers that have electronic trip units with communication capabilities. They can also generate data. Power Defense circuit breakers can reduce arc flash-related incidents. They support multiple mounting methods and current ratings as high as 800 Amps. The Power Defense series includes 3-pole and 4-pole models. Additionally, different models support the same universal cutout dimensions. Power Defense circuit breakers also support automatic adjustment for locating the central position. Some breaker models are thermal-magnetic, some are single-magnetic, and some are electronic.
