Scope of application

♦S7D series circuit breakers have the advantages of small apperance, light weight, excellent and reliable functions, higher breaking capacity, rapid tripping and long life.
♦As for the guide installation, case and partes, they adopt high resistance and impact resistance plastics.
♦They are mainly applied to the AC 50Hz/60Hz circuit with rated operation volage 415V or less provid circuits with overload and short-circuit protections, and to make and break the electrical device and lighting circuit infequently.
♦The product can be installed with undervoltage release and shunt release, and also can be used for separating, and protecting the undervoltage of the circuit and breaking the long distance.
