DC SPD Replacement Cartridges — Frequently Asked Questions
What is a DC SPD cartridge?
A replaceable plug-in module inside CNC DC SPDs (YCS6 series). When the SPD absorbs cumulative surge energy and the status flag turns red, you replace just the cartridge instead of the entire housing — saves cost and install time.
Price of DC SPD cartridge in Pakistan?
Cartridges range from Rs.1,800 (500 V) to Rs.3,900 (1500 V) depending on voltage rating. Always replace with matching voltage — never substitute lower-rated for higher.
How often do I replace cartridges?
When the SPD status flag changes from green to red — indicates the MOV has absorbed its lifetime joule rating. In typical Pakistani monsoon conditions, 5-8 years between replacements.
Can I replace just one cartridge in a multi-pole SPD?
Yes — each cartridge is independent. Replace only the one with the red flag. The intact cartridges continue to protect their poles.
