Description
50kA Type 1+2 Surge Protection Device
Niglon SP12S-1PN Single Pole + Neutral Lightning & Surge Arrestor
The Niglon SP12S-1PN 50kA Type 1+2 Surge Protection Device (SPD) is a compact and high-performance solution designed to protect electrical installations from transient overvoltages and lightning strikes. This two-module SPD is suitable for use in incoming distribution panels, particularly in buildings with lightning protection systems or high-risk environments.
Featuring MOV-based surge protection technology, this SPD ensures effective dissipation of high-energy surges, safeguarding sensitive electrical equipment. It comes with a remote signal contact for external monitoring, along with an intuitive green/red fault indicator for instant visual status checks.
