MC4 Connector with 20A Fuse DC 1000V | Safe Solar Power Connection

MC4 connector with fuse is a compact solar protection part that combines a PV connector and inline overcurrent protection in one unit for Pakistan. This CNC Electric Pakistan MC4 fuse connector is rated for 1000V DC, available with 20A or 30A fuse options, and built for outdoor solar string wiring with IP67 protection. Starting from Rs.700, it is a smart option when you want fewer joints, easier installation, and neat string protection on rooftop systems powering ACs, pumps, fridges, and inverter-backed homes.

Quick Specs

What This Product Does

This product connects a solar cable like a standard MC4 connector and at the same time adds a fuse in the same assembly. That means fewer separate parts, fewer connection points, and a cleaner installation path when compared with using a separate connector plus separate fuse holder on a small rooftop job. People searching for mc4 connector with fuse, mc4 fuse connector, inline fuse solar, or solar string fuse connector are usually looking for this exact convenience.

On home solar systems in Pakistan, it can be useful where the installer wants simple string protection without adding more space-consuming hardware. It does not directly protect a 1 ton AC, 1.5 ton AC, 2 ton AC, geyser, fridge, or washing machine on the AC side, but it protects the DC solar path that feeds the inverter which then supports those loads.

Compared with the MC4 4mm normal pin or MC4 6mm solid pin, this model adds overcurrent protection. Compared with a separate DC fuse holder and DC fuse, it can save space and reduce extra connection points.

Why Installers Like the Fused MC4 Format

Every extra joint on a DC line is another place where a bad crimp, looseness, or moisture problem can appear. By combining the connection and fuse function, the fused MC4 format can make compact jobs simpler and cleaner. This is especially attractive on small rooftop systems where enclosure space is limited and installation speed matters.

It is not the right answer for every project. On larger systems, many installers still prefer a centralized solar DB bundle with separate fuses, breakers, and SPDs. But for selected string-level use cases, the fused MC4 is a practical and tidy solution that also keeps the bill of material simple.

Selection Guide

How to Install

This product still needs correct cable preparation and proper understanding of the string design. The fuse rating must match the PV application.

• Confirm whether your design needs the 20A or 30A fuse option.
• Prepare and terminate the PV cable correctly using the proper crimping tool.
• Install the fused connector in the intended string position and confirm correct polarity.
• Check continuity, locking, and waterproof sealing before energizing the DC line.
• Replace the fuse only after the cause of the fault has been identified.

What This Product Does NOT Protect Against

This fused MC4 provides inline overcurrent protection, but it does not protect against lightning or fast surges. For that you need a DC SPD. It does not replace a full DC breaker where switching and resettable protection are needed. It also does not protect the AC side of the installation, and it does not provide earth leakage protection or voltage regulation.

Think of it as a compact connector-plus-fuse device. For a complete system, combine it with DC 2P MCB 500V, DC SPD 1000V, proper DC cable, and a suitable solar DB solution if the project requires one.

Cross-Category Recommendations

If you are buying this fused MC4 connector, compare it with the MC4 4mm normal pin and MC4 6mm solid pin to decide whether you need a standard connector or an integrated protection connector. If you want centralized protection, compare the DC fuse holder and DC fuse. For resettable switching, compare the DC 2P MCB 500V. For complete design guidance, read the solar DB box guide.

Browse MC4 connectors, DC cables, DC circuit breakers, DC SPD collection, solar bundles, AC circuit breakers, AC SPDs, voltage protectors, RCCB and RCBO, manual changeover switches, automatic transfer switches, DB boxes, and MCCBs for complete protection planning.

FAQs

What is an MC4 connector with fuse?

It is a solar connector assembly that combines the normal MC4 connection function with inline fuse protection in the same unit.

What is mc4 connector price in pakistan for the fused version?

This fused version starts from Rs.700, which is higher than a standard connector because it adds built-in overcurrent protection.

Should I choose 20A or 30A?

Choose the fuse rating according to the actual solar string design and installer recommendation. The fuse must match the current requirements of the PV application.

Is this better than a separate fuse holder?

It can be better for compact jobs because it saves space and reduces extra joints. Separate holders are often preferred in larger centralized DB layouts.

Can I use this on outdoor rooftops?

Yes, it is listed as IP67 waterproof for solar rooftop use, provided it is installed correctly.

Does this replace a DC breaker?

No. It adds fuse protection, but it does not fully replace a dedicated DC breaker where resettable switching or broader control is required.

Can I use this on 4mm and 6mm cable?

Use it only with the cable size and installation method it is intended for. If the project specifically needs a 6mm connector, compare the 6mm solid pin model.

Does this protect against lightning?

No. Lightning and transient surge protection require a DC SPD.
