AC SPD Cartridges

About

What are AC SPD replaceable cartridges? Field-replaceable MOV (metal-oxide varistor) cartridges that plug into a YCS6-B base. When the SPD absorbs a surge event and the cartridge indicator turns red (end-of-life), pull out the spent cartridge + plug in a new one — no need to rewire. Cartridge cost PKR 800-2,500; replacement < 30 seconds. Built to IEC 61643-11. Protect your solar and electrical installations with high-performance CNC Electric AC SPD Cartridges , designed to safeguard your system from dangerous voltage spikes, lightning surges, and grid fluctuations.
