• Current range: 2 A to 630 A

• Fuse types: gG (general-purpose), aM (motor protection)

• Standards: DIN VDE 0636, IEC 60269

• Common part numbers: 80NHG000B, 160NHG1B, 400NHG3B

NH Fuses 690 V AC/DC – High Voltage Protection for Demanding Environments

For higher-voltage industrial systems, infrastructure, power plants, or railway installations, Eaton Bussmann 690 V NH fuses provide maximum protection. These high-performance fuses are available in NH1 to NH3 sizes and meet stringent requirements for breaking capacity and arc resistance. Suitable for both AC and DC systems.

Technical Features:

• Voltage rating: 690 V AC / DC

• Sizes: NH1, NH2, NH3

• Current range: 32 A to 630 A

• Fuse types: gG, aM, gTr (transformer protection)

• High short-circuit strength (up to 120 kA depending on the model)

• Common part numbers: 125NHG2B690, 250NHG3B690, 500NHG3B690DC

NH Fuses 1000 V DC – Designed for Photovoltaics and Battery Storage

In renewable energy systems, especially solar and battery storage, Eaton Bussmann’s 1000 V DC NH fuses offer reliable protection against DC faults. These gPV-type fuses are optimized for use in high-voltage DC circuits, such as PV inverters, battery systems, and EV charging infrastructure. Available in special NH1XL, NH2XL, and NH3XL sizes.

Technical Features:

• Voltage rating: up to 1000 V DC

• Sizes: NH1XL, NH2XL, NH3XL

• Current range: 80 A to 630 A

• Fuse type: gPV (photovoltaic protection)

• High-performance DC arc interruption

• Common part numbers: NH1XL1000VDC, NH2XL-Bat, NH3XL1000VDC
