LV Surge Protection Devices

Product catalog summary

General Information
Surge protection devices are designed to safeguard electrical equipment from overvoltages caused by lightning. They can be installed on main and auxiliary panels, and even near sockets for precise protection. These devices comply with German standard VDE 0675-6, international standard IEC 61643-1, and European standard EN 61643-11.

Surge Arrester Classes
- Class B, Type 1, Class I: Used for main distribution panels with a maximum protection capacity of 100kA.
- Class C, Type 2, Class II: Used for distribution boxes with a maximum protection capacity of 40kA.
- Class D, Type 3, Class III: Used in auxiliary tables with a maximum protection capacity of 5kA.

Key Specifications
- Up Protection Level: The reduced high voltage value due to lightning, ranging from 1 to 2.5 kV.
- Imax, Maximum Current Rate: The maximum discharge current the arrester can withstand once, expressed in kA.
- In, Rated Current Rate: The current rate during testing that the arrester can conduct without issues, expressed in kA.
- Uc, Surge Arrester Operating Voltage: The maximum operating voltage under normal conditions, expressed in V.

Product Connection and Technical Dimensions
Each class and type of surge arrester has specific connection diagrams and technical dimensions to ensure proper installation and functionality.

Order Information
Details on the types, definitions, number of poles, operating voltage, maximum current, rated current, and protection level are provided for ordering purposes. Note that LV surge arresters, except for type B, come with a fault signal contact.
