DC SPD 600V In=20KA Imax=40KA CARTRIDGE Surge Protection Devices YCBS6-C

DC SPD cartridge 600V is the replacement part you buy when the original surge cartridge in your DC surge protection device has been spent or needs to be matched to a 600V DC installation. On the live CNC Electric Pakistan page, this cartridge is listed at Rs.850 as a 1P DC SPD cartridge with In 20kA and Imax 40kA. For hybrid solar strings, battery-side DC panels, telecom DC boards, and compact energy systems, that makes it a practical service item rather than a decorative accessory.

Key Features

• DC SPD cartridge for 600V systems — 1P format
• Nominal discharge current In = 20kA
• Maximum discharge current Imax = 40kA
• Replacement item for existing SPD bases in 600V DC protection layouts
• Suited to hybrid solar, lower-voltage DC strings, battery DC boards, and 600V-class DC protection
• Cheaper and faster than replacing a full SPD assembly when the base is still serviceable

Technical Specifications

Exact dimensions, response time, base-compatibility table, and terminal geometry are not currently listed on the live local page and have not been guessed.

Variant & Price (Live on Shopify)

Single cartridge variant. This is a replacement cartridge only, not a complete SPD assembly. If your base is also damaged or missing, buy a full DC SPD from the DC SPD collection.

Applications

This cartridge belongs in service and replacement work. In Lahore, hybrid solar and battery-backed residential systems often use lower-voltage DC protection where a 600V replacement cartridge makes sense. In Karachi, telecom DC boards and rooftop hybrid jobs fall into the same range. In Islamabad and Rawalpindi, backup-power installations using batteries and protected DC feeders may need cartridge replacement when the main base is still sound.

How to Choose

What This Product Does NOT Protect Against

This cartridge does not replace a full SPD base if the base itself is damaged. It does not replace a correctly sized DC breaker, a proper DC fuse, or a suitable DC isolator. It does not correct bad earthing, poor cable routing, or wrong voltage class in the PV or battery circuit.

Installation Guide

1. Confirm the installed SPD base accepts this cartridge class and that the panel is built for a 600V DC protection stage.
2. Isolate the DC circuit using the correct DC isolator and safe shutdown procedure.
3. Remove only the old cartridge if the base is still serviceable.
4. Fit the replacement cartridge firmly and recheck the rest of the SPD path, breaker/fuse coordination, and earthing.
5. Re-energise and verify the rest of the DC protection stack matches the real system voltage class.

FAQs

Price?
Rs.850 for the 1P 600V DC SPD cartridge YCS6-C.

Full SPD or cartridge only?
Cartridge only. For the full assembly, see the DC SPD collection.

What do In 20kA and Imax 40kA mean?
They describe the cartridge's surge-handling class for the DC protection stage.

Can I use this 600V cartridge in place of a 1000V cartridge?
No. Match the cartridge to the installed SPD voltage class.

Useful for Pakistani solar systems?
Yes, if the system uses a matching 600V DC surge-protection stage.

When to buy a full SPD instead?
When the base is damaged, missing, mismatched, or you are building the protection stage from zero.
