Eaton 100NHG1B Series Tag Fuse, 100A Current Rating, 500V Voltage - 100NHG1B
This tag fuse provides overcurrent protection for power distribution in renewable and industrial settings, designed for use in systems requiring Rapid interruption of fault currents. It operates as a high-capacity, NH-style protective element suitable for installations where reliable short-circuit clearance and compatibility with NH fuse holders are required.
Features and Benefits:
• 100A current rating enables protection of medium-current circuits
• 500V rated insulation supports high-voltage DC and AC systems
• gL fuse speed delivers fast-clearing performance for faults
• High rupture capacity prevents catastrophic failure under fault
• Complies with IEC60269-1 to maintain standardised interchangeability
• DIN43620 mounting profile ensures compatibility with NH holders
• 500V rated insulation supports high-voltage DC and AC systems
• gL fuse speed delivers fast-clearing performance for faults
• High rupture capacity prevents catastrophic failure under fault
• Complies with IEC60269-1 to maintain standardised interchangeability
• DIN43620 mounting profile ensures compatibility with NH holders
Applications
• Suitable for photovoltaic array string protection in PV systems
• Ideal for wind turbine internal distribution circuits
• Used with industrial switchgear for motor and feeder protection
• Can be used for utility sub-distribution and outgoing feeders
• Suitable for integration into automation control panels

What physical form factor does it use for panel installation?
The device is supplied in a 40x135mm NH fuse format compatible with standard NH fuse clips and holders.
How does its construction affect replacement selection?
Its high rupture capability and gL characteristic mean replacements must match both speed type and rupture rating to preserve fault-control performance.
Which standards are referenced for interchangeability and testing?
Compliance is with IEC60269-1 and DIN43620 which define dimensional, performance and testing criteria for NH fuses.
Is it suitable for both AC and DC service environments?
The voltage rating of 500V permits use across specified AC and DC systems within that maximum voltage.
