Surge Protection S400LV-1
High Efficiency Surge Protections are designed to protect systems and electrical devices against pulses and transient overvoltages determined by atmospheric origin and electrical operations. These are used in the lightning and overvoltage protection systems between the Lightning Protection Zone 0A (LPZ 0A) and LPZ 1 (please refer to the image below). This kind of SPD has to repeatedly conduct partial lightning currents with 10/350 μs waveform preventing their propagation into the electrical installation of the structure.
- The creation of a protection system against lightnings and overvoltages for electrical installations is a fundamental infrastructure requirement for a complex functioning and noise-free electrical and electronic system.
- The SPD requirements for the realization of such a system of protection against lightning and overvoltages refer to the lightning protection zones concept according to IEC EN 62305-4 and defined in IEC EN 60364 5-534.
- These are used in the lightning and overvoltage protection systems between the Lightning Protection Zone 0A (LPZ 0A) and LPZ 1 (please refer to the image below).
- This kind of SPD has to repeatedly conduct partial lightning currents with 10/350 μs waveform preventing their propagation into the electrical installation of the structure.
- Type 2 SPDs are commonly used between LPZ 0B and LPZ 1 or between LPZ 1 and LPZ 2, their discharge capacity is about of some tens of kA (8/20 μs).
