IEC 60269-7 gBat NH fuse-links for battery energy storage systems: full-range protection, DC breaking capacity up to 150 kA; NH1 / NH2 at 1000 V DC, NH1XL / NH2XL / NH3L at 1500 V DC.
NH gBat Battery Protection Fuse-Links (1000 – 1500 V DC)
The Mersen NH gBat series was engineered specifically for the protection of battery systems. It offers full-range protection, safely clearing very small overcurrents as well as DC fault currents up to 150 kA.
The range covers various ratings at 1000 V DC in NH1 and NH2 sizes, and at 1500 V DC in NH1XL, NH2XL and NH3L sizes. The fuses are of the gBat type that complies with the new IEC 60269-7 standard for battery protection, and are available with bolted blades for direct mounting or with plain blades.
Applications: electrical energy storage (BESS), battery storage systems, line protection between the battery system and the DC/DC converter or battery inverter, DC grid protection.
