Description
40kA Type 2 Surge Protection Device
Niglon SP23S-1PN – Single Pole + Neutral Lightning & Surge Arrestor
The Niglon SP23S-1PN 40kA Type 2 Surge Protection Device (SPD) is a high-performance surge arrestor, designed to protect electrical installations from transient overvoltages caused by lightning strikes and power fluctuations. This 2-module SPD is suitable for use in distribution panels, offering effective suppression of high-energy surges in commercial and industrial environments.
Equipped with a remote signal contact, the SP23S-1PN allows for external monitoring, ensuring quick detection of system faults. The green/red fault indicator provides a clear visual status, while its compact DIN rail-mounted design ensures easy integration into existing electrical systems.
