Description
Niglon SP23S-3PN/C40KA 40kA Type 2 Surge Protection Device
Three Pole + Neutral Lightning & Surge Arrestor with Remote Contact
The Niglon SP23S-3PN/C40KA 40kA Type 2 Surge Protection Device (SPD) is a high-performance surge protection solution, designed to protect electrical installations from transient overvoltages caused by switching operations and indirect lightning strikes. This compact two-module SPD is suitable for distribution panels in areas with low exposure to lightning, ensuring reliable protection for sensitive electrical equipment in commercial and industrial environments.
Built with high-energy MOV and GDT protective elements, this SPD provides efficient surge suppression and enhanced durability. It features a remote signal contact for external monitoring, allowing for quick fault detection, while its green/red fault indicator ensures easy visual status checks.
