ABB S2C-DH Industrial Control Safety Relay Module

ABB S2C-DH is a rotary operating mechanism accessory for ABB S2C miniature circuit breakers, providing a robust manual drive for safe isolation in control panels. It supports 2-, 3-, and 4-pole configurations and is designed for use with S200U, S200UP, SU200PR, and S200UDC breakers within the S2C family. The mechanism attaches to the breaker assembly to enable hand-operated control, allowing precise opening and closing of the circuit during maintenance, testing, or emergency isolation in industrial environments. By integrating with ABB's safety-focused MCCB lineup, the S2C-DH preserves the protective function of the breaker while delivering reliable mechanical operation and clear, tactile feedback for operators. When installed as part of a panel that uses S2C devices, this rotary mechanism helps ensure straightforward manual control in harsh factory conditions, contributing to safer, more efficient maintenance routines.
