Description
40kA Type 2 Surge Protection Device
Niglon SP23S-1PN/C40KA – Single Pole + Neutral Lightning & Surge Arrestor
The Niglon SP23S-1PN/C40KA 40kA Type 2 Surge Protection Device (SPD) is a compact and efficient lightning and surge arrestor, designed to protect electrical installations from transient overvoltages. Suitable for distribution panels, this SPD ensures optimal protection for sensitive equipment in commercial and industrial environments.
Featuring a single-module DIN rail mounting design, this Type 2 SPD integrates a high-energy MOV & GDT protective element, providing superior suppression against electrical surges. It includes a remote contact for external monitoring, allowing for quick detection of failures, while the green/red fault indicator ensures easy visual status checks.
