Fuse link - NHS00/80 UQ01 aR 350A/690V - ultra-fast / screw terminals S 004371122

Fuse link NHS00/80 UQ01 aR 350A/690V is a component designed to protect electrical installations, especially semiconductor devices. Its construction based on the NH-S standard, in size NH00, provides reliable protection against the effects of short circuits and overloads.

Characteristics and application

This fuse with a rated current of 350A and a rated voltage of 690V AC is characterized by an ultra-fast response (aR) – which is crucial for protecting sensitive semiconductor elements. The aR characteristic means that the fuse reacts very quickly to short-circuit currents, minimizing the duration of failures and potential damage. Use in power circuits for semiconductor devices guarantees their safe and long-lasting operation. The top indicator allows for quick visual identification of a blown fuse.

Construction and parameters

The construction of the fuse link is based on solid materials, which translates into high reliability and durability. The rated breaking capacity of 200 kA ensures effective protection even with high short-circuit currents. Power losses of 60W are typical for this type of protection and do not significantly affect the energy efficiency of the installation. The total Joule integral of switching at 100,000 A²s indicates the large amount of energy that the fuse can absorb during short-circuit switching.

It is worth noting that the lack of metal insulated grips (IMGL) simplifies the installation and removal of the fuse link, but requires taking appropriate safety precautions when working under voltage. Compliance with IEC 60269-4 confirms compliance with European safety and quality standards.
