AC SPD Replacement Cartridges — Frequently Asked Questions
What is an AC SPD cartridge?
Replaceable plug-in MOV module inside CNC AC SPDs. When status flag turns red, swap just the cartridge instead of the whole device.
Price of AC SPD cartridge?
AC SPD cartridges start from Rs.450 for 1P+N standard duty. Higher-discharge variants Rs.850-1,400.
Do AC and DC SPD cartridges interchange?
No — never. AC and DC cartridges have different arc-extinguishing technology. Wrong type causes fire on first surge.
Can I keep spare cartridges on hand?
Recommended. After a major thunderstorm season, keep 2-3 spares for each SPD in critical installs.
