12NES1200T is a rating-plug accessory manufactured by Eaton for use with Series C ND-frame molded-case circuit breakers. It allows the breaker to be set for a specific rated current of 1200 A, enabling field adjustment of the breaker trip rating. This rating plug is designed for compatibility with Eaton Series C ND, HND, NDC, NDU, and related frames, and is intended for use with electronic trip units such as DIGITRIP, RMS310, and NES.
