What are the main applications of fault arc protectors?

    Arc protection devices are widely used in power systems such as medium and low voltage switchgear and substations, and are particularly important in the following scenarios:
Medium and low voltage switchgear: used to detect and quickly cut off arc phenomena caused by short circuit faults, avoiding equipment damage and personnel injury,
Substation: Protecting critical equipment from arc faults and ensuring stable operation of the power system.

What is the function of an arc protector?

   Arc protectors are essential in electrical equipment as they can provide excellent safety protection. It can effectively prevent electrical accidents and ensure the safety of employees’ lives. Installing arc protectors in electrical equipment is also one of the necessary means to ensure the production safety of enterprises.
