Solar MC4 Compatible In-line Solar Fuse – 10A / 20A / 30A
MC4 Compatible In-line Solar Fuse Connector – 10A / 20A / 30A
Upgrade your solar setup with our MC4 Compatible In-line Solar Fuse Connector—a high-quality component designed for safety, durability, and ease of use. Perfect for both professional and DIY solar applications, this connector offers secure energy transfer and environmental protection for any solar array.
Why You Need Fuse Connectors in Your Solar System
In-line fuse connectors play a critical role in protecting your solar system from potential electrical faults. They act as a safety barrier by automatically breaking the circuit when the current exceeds the rated capacity. This helps to:
- Prevent overheating and potential fires
- Protect cables, panels, and other components from overcurrent damage
- Minimise downtime and costly repairs
- Ensure compliance with solar installation safety standards
Without proper fusing, your system is vulnerable to serious failures that can impact performance, safety, and warranty coverage. These in-line fuse connectors are the easiest and most reliable way to protect your investment.
Key Features:
- Plug & Play Installation: Simple, quick integration into your existing MC4-compatible wiring—no special tools required.
- Weatherproof and Durable: Rated to IP67 when mated and IP2X when unmated, it resists water, dust, UV exposure, and corrosion.
- High-Quality Materials: Built with tinned copper alloy contacts and PC/PPO insulation for reliable, long-term use.
- Rated for High Voltage: Supports systems up to 1000V DC with low contact resistance (≤0.5mΩ).
- Available in 3 Fuse Ratings: Choose from 10A, 20A, or 30A depending on your system requirements.
