In-line Solar Fuse Connector for Safe and Reliable PV System Protection
Integrated Overcurrent Protection for Solar Arrays
The Exotronic In-line Solar Fuse Connector combines a standard Ø 4 mm solar connector with a built-in fuse, providing essential overcurrent protection for individual panel strings or parallel connections. This design helps prevent damage to solar panels and wiring in the event of a fault, reducing the risk of fire and equipment failure. With a rated current of 20A, it is suited to a wide range of photovoltaic installations, from small caravan solar systems to larger off-grid arrays.
Engineered for Harsh Australian Conditions
Built to perform in demanding environments, this connector features an IP67 waterproof and dustproof rating when mated, ensuring reliable operation even in heavy rain or dusty outback settings. The PC/PPO insulation material is UV-resistant and carries a UL94-V0 flame class rating, adding an extra layer of safety. A wide operating temperature range of –40°C to +90°C (with an upper limit of +105°C) means it can handle extreme heat and cold without compromising performance.
Secure Connection with Snap-in Locking
The snap-in locking system ensures a firm, vibration-resistant connection that won’t loosen over time, critical for mobile applications such as caravans, 4WDs, and marine solar setups. Tinned copper contacts with a low contact resistance of 0.5 mΩ minimise power loss, while the 1000V DC (IEC) voltage rating makes it suitable for high-voltage series strings. The connector also meets salt mist spray test severity 5 (IEC 60068-2-52), confirming its suitability for coastal and marine environments.
