DC Installation Safety – NH00 100A/440V Fuse Link

The NH00 fuse link is a reliable safety element protecting direct current (DC) circuits from the effects of overloads and short circuits. Designed to work with installations up to 440V DC and a rated current of 100A, it is a key element of protection in applications requiring high stability and safety.

Protection and application

The NH00 fuse link, thanks to its gR characteristic, provides effective protection of semiconductor elements. This means that it reacts in a coordinated manner to short-term current surges, typical of starting motors or other devices with high power consumption, while immediately interrupting the circuit in the event of a short circuit. This is particularly important in uninterruptible power supply (UPS) systems, photovoltaic installations or electric vehicle chargers – everywhere where voltage stability and protection against damage are a priority.

Construction and features

The construction of the NH00 fuse link has been designed with ease of installation and reliable operation in mind. It has a trip indicator located on the top of the housing, allowing for quick visual identification of a blown fuse – saving time during diagnostics and repairs. The lack of metal insulated grips (IMGL) simplifies mounting in standard fuse holders. The short-circuit breaking capacity at 50kA guarantees the safety of the installation even in the event of serious disturbances.

• A rated current of 100A provides adequate protection for circuits with medium power consumption.
• A rated DC voltage of up to 440V enables use in a wide range of DC installations.
• The gR characteristic is dedicated to the protection of semiconductor elements, providing a coordinated response to overloads and short circuits.
• The trip indicator facilitates quick identification of a blown fuse.
• High short-circuit breaking capacity – 50kA – guarantees installation safety.
• Lightweight design (weight 0.173 kg) facilitates installation and replacement.
