Roewe factory direct sales two-speed control and protection switch

Control and protection switching appliances, functions and uses
It adopts a modular single product structure and integrates traditional circuit breakers (fuses), contactors, overload (or overcurrent, phase failure) protective relays and starters The main functions of low-voltage products such as height dividers and motor comprehensive protectors include remote automatic control and local direct insertion force control functions, panel indication and electromechanical signal alarm functions, overvoltage and undervoltage protection functions, and phase failure functions. Phase loss protection function, under-current and under-power protection function, and coordinated time current protection characteristics (with overload inverse time limit, definite time limit, short circuit instantaneous, and extremely large short circuit instantaneous four-stage protection characteristics). By selecting functional modules or accessories as needed, you can control and protect various motor loads and distribution loads.
