Overview
The CKP1 series surge protective devices (SPDs) are suitable for use in AC 50/60 Hz power supply systems (or telecommunications systems) with a rated voltage of up to 380 V, providing protection against surges caused by indirect and direct lightning strikes or other transient overvoltages.
The SPD complies with GB 188021-2002/IEC 61643-1:1988 and GB 50057-2002 'Code for Lightning Protection Design of Buildings'. The SPD offers protection modes including phase-to-phase, phase-to-earth, phase-to-neutral, neutral-to-earth, and combinations thereof.
The SPD is suitable for surge protection requirements in residential, commercial and industrial sectors.
