Feature:1. Surge Protector: When a overvoltage surge occurs in the system due to lightening strike or other reasons, the protector immediately opens quickly within nanoseconds, and introduces the overvoltage surge into the ground to protecting the electrical equipment.2. Stable in Works: High in accuracy and strong in electrical conductivity, the voltage comes with 385V AC maximum continuous working voltage.3. Safe Protection: Offers protection for electrical systems and electrical load appliances from lightning strikes and transient overvoltage.4. Good Durability: Adopting flame retardant PC material with modular structure, this voltage arrester has great durability for long term use.5. Easy to Install: Standard 36mm rail mount enables the volt protector quick response, easy installation and simple maintenance as well.Specification:Item Type: Surge Protective DeviceModel: LTD1-C40Material: Flame retardant PC.
