Description
40kA Type 2 Surge Protection Device
Niglon SP23S-3PN/40KA – 3 Pole + Neutral Lightning & Surge Arrestor with Remote Contact
The Niglon SP23S-3PN/40KA 40kA Type 2 Surge Protection Device (SPD) is a four-module combined lightning and surge arrestor, designed to protect electrical installations from transient overvoltages. Ideal for distribution panels, this SPD is particularly suited for areas with low exposure to lightning strikes, ensuring reliable protection for sensitive equipment in commercial and industrial environments.
Built with a high-energy MOV protective element, this SPD provides efficient surge suppression. 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.
