1. Surge Protector: When a overvoltage surge occurs in the system due to lightening strike or other reasons, the protector opens quickly within nanoseconds, and introduces the overvoltage surge into the ground to protecting the electrical equipment.
2. Reliable Working: With 20kA nominal discharge current In and 40kA maximum discharge current Imaximum to ensure the electrical safety.
3. Safe Protection: The 1000V DC maximum continuous working voltage Uc ensures easier circuit operating as well as higher efficiency.
4. Good Durability: Adopting flame retardant PC materials with modular structure, the voltage arrester is very for long use.
5. Easy to Install: Standard 36mm rail mount enables stable work performance in combination with distribution box and circuit breaker.
