DF Electric din-rail mounted fuse holders provide secure and reliable housing for a range of fuses including, cylindrical and NH type fuses. Designed to offer optimal protection and easy installation across various applications.

Cartridge/ cylindrical fuses are low cost electrical safety devices designed for overload protection in circuits. They are a cylindrical shape and our fuses come in different sizes such as 9x32mm, 10x38mm, 14x51mm and 22x58mm. They feature contact points at each end and are typically made from ceramic. DF Electrics cylindrical fuses come in 2 different speed ratings: gG and aM. gG fuses are used for general circuit protection which can include protecting cables, powerlines and equipment whereas, aM fuses are best at protecting circuits where high inrush currents are expected for example when motors or LED lighting are used.

NH fuse bases are mounting bases specifically designed to hold NH (or \"knife blade\") fuses, commonly used in industrial and high-power applications. These bases provide a secure and efficient connection for NH fuses.

Key Features of NH Fuse Bases

• Compatibility – Designed for NH fuses, available in sizes ranging from NH00 to NH4.
• Safety – Offers secure and stable mounting for fuses, often with optional covers or guards for additional protection.
• Applications – Commonly used in power distribution systems, motor protection, and industrial panels.

gPV fuses are available in several sizes/ formats from cylindrical to Nh type fuses. These fuses are specifically designed for photovoltaic (PV) and solar applications. gPV fuses meet the required requirements and standards set out for the photovoltaic industry and are designed to withstand the the temperatures and outdoor environments these fuses will be commonly subjected to.

Cylindrical and Nh gBat fuse links from DF Electric are specifically designed to protect battery systems in compliance with IEC 60269-7 standards. These fuses are designed to protect battery systems from all types of overcurrents, including overloads and short circuits, providing comprehensive protection for batteries, cables, and the associated switchgear in the installation. gBat fuses help enhance the safety and longevity of battery storage systems by preventing potential damage caused by electrical faults. They are suitable for various applications, including renewable energy storage, electric vehicles, and industrial battery systems. By using DF Electric gBat fuses, you can ensure reliable operation and protection for your battery systems, minimising downtime and maintenance costs.
