LPI® Surge Protection: LPI SGT50-25

· Product Description
The LPI SGT50-25 is a high performance encapsulated spark gap offering a high surge rating with low follow on current,
ideal for point of entry protection. The LPI SGT50-25 is intended for installation within the lightning protection zone
concept at the boundaries LPZ O A(B) -1 according to IEC 1312-1.
The LPI SGT50-25 has been designed for the protection of Phase to Neutral, Phase to Earth, or Phase to Neutral-Earth
protection in LV supply systems.
Follow on current performance of these devices is kept within acceptable levels by the rapid extinguishment of the arc
allowing transients to be clamped without activating upstream protection devices.
