The S2C-DH is a handle mechanism accessory designed for use with S200U, S200UP, SU200PR, and S200UDC series miniature circuit breakers. Its primary function is to serve as a rotary operating mechanism, enabling 'through the door' operation of a breaker mounted inside an enclosure. This provides a convenient and safe way to externally control the circuit breaker without opening the panel door. Please note that right-hand mount accessories cannot be used in conjunction with the S2C-DH mechanism.
