MC4 Inline Fuse Connector — Crimp Style, IP67 Waterproof
Product Description
The MC4 Inline Fuse Connector is designed to provide integrated overcurrent protection directly within solar PV string wiring, serving as a critical link between solar modules and downstream equipment such as inverters, charge controllers, and combiner boxes.
Unlike traditional bracket-mounted 10×85 mm fuse holders, this connector incorporates the fuse into an MC4-compatible inline housing using crimped electrical terminations. This approach improves mechanical stability, minimizes contact resistance, and reduces long-term failure risk caused by vibration, thermal cycling, or loose connections.
Built for harsh outdoor environments, the connector features UV-resistant materials and an IP67 waterproof rating when properly mated. Its compact inline design supports fast installation, simplified maintenance, and quick fuse replacement—making it ideal for residential, commercial, and utility-scale solar installations requiring reliable, code-conscious protection.
