Introduction
Photovoltaic (PV) fuse links are essential components designed to protect photovoltaic inverters and their associated systems from overcurrents and short circuits.

Photovoltaic (PV) fuse links are essential components designed to protect photovoltaic inverters and their associated systems from overcurrents and short circuits.

Load switching capacity up to 800V a.c.
Compliance with IEC photovoltaic standards.
Designed to protect against a full range of overcurrents.
High temperature and internal pressure-resistant ceramic material.
High breaking capacity.
ETI is one of the first among the producers of NH fuse-links to have developed a new generation of NH gG fuse-links, specifically designed for cable protection in 800V a.c. systems. Featuring an innovative design of melting elements and the adoption of high-temperature and internal pressure-resistant ceramic material, these NH fuse-links’ constructions can now be incorporated into standard NH size dimensions.
Currently, ETI offers NH00, NH1, NH2, NH3C, and NH3 gG fuse-links, with rated currents ranging from 6A to 400A, designed and tested for 800V a.c. systems. These fuse-links have very low dissipation and high breaking capacity. Upon customer request, we are also prepared to develop fuse-links for even higher rated currents.
For cable protection on the a.c. side of 1500V PV inverters
