NH fuse links with gG characteristic are used to protect conductors and devices. They represent a deliberately weakened part of the electrical circuit, which interrupts the current in case of overload or short circuit, and thus ensures the protection of more expensive components of the circuit. The most important part of the fuse-link is the melting element. It must be properly perforated to ensure the desired operation of the fuse-link and comply with the IEC standard. Our innovation is in the determination of the appropriate perforation, which allows for the same or better technical characteristics compared to our main competitors. The main advantages of the new series of NH fuse-links are reduced power dissipation stability of the characteristic wide range of different types and certification coverage. This innovation, in coordination with other activities, enables the fulfillment of the ETI’s planned strategy.
