CNC YCS6-C 2P solar DC surge protection device

The CNC YCS6-C 2P DC SPD is designed to help protect compatible solar PV and DC electrical systems against transient voltage surges. For solar installations, surge protection is particularly important because PV panels and their connecting cables can be exposed to lightning-related surges and switching transients. A correctly selected DC surge protection device can help divert damaging surge energy away from sensitive equipment such as solar inverters and other DC-side components.

This 2-pole CNC YCS6-C surge protection device is suitable for applications where a dedicated DC SPD is required on the solar or DC side of an installation. The unit is commonly considered for solar PV protection, DC distribution arrangements and compatible inverter installations. Before installation, the SPD’s voltage rating must be matched to the actual system and PV string voltage.

The CNC YCS6-C 2P DC SPD is specified with a nominal discharge current of 20kA and maximum discharge current of 40kA, based on current listings for this model. Some suppliers offer different voltage variants, including 600V and 1000V DC, so buyers should select the correct version for their installation rather than choosing only by price.

For a solar installer or system owner in Pakistan, choosing the correct SPD is an important part of the overall protection arrangement. The device should be installed according to the manufacturer’s requirements and coordinated with appropriate DC breakers, isolation equipment, earthing and the solar system design.

HN Electric supplies solar protection and electrical products across Pakistan, including DC breakers, SPDs, distribution boxes and related solar accessories. Its existing solar-products category already groups SPDs with other solar protection equipment.

Before purchasing, confirm whether you need the 600V DC or 1000V DC version, as well as the required pole configuration and electrical ratings. For professional installations, a qualified electrician or solar installer should verify compatibility with the PV array and inverter.

FAQs

1. What is the CNC YCS6-C 2P DC SPD used for?

It is a DC surge protection device designed for compatible solar PV and DC electrical installations to help protect equipment from transient voltage surges.

2. What is the current rating of the YCS6-C 2P DC SPD?

Current listings specify 20kA nominal discharge current (In) and 40kA maximum discharge current (Imax).

3. Is this SPD suitable for solar panels?

Yes, the YCS6-C 2P DC SPD is commonly marketed for solar PV and DC-side protection. The correct voltage variant must match the solar system.

4. Should I use a DC SPD or AC SPD for solar panels?

For the DC side between the PV array and inverter, use an appropriately rated DC SPD. AC and DC SPDs should not be treated as interchangeable; the voltage and current type must match the installation. HN Electric’s own guide also distinguishes the DC and AC sides of a solar installation.
