Description
The Eaton Bussmann 50NHG000B is a 50A rated NH size 000 low-voltage DIN-type dual fuse link manufactured to class gL-gG in compliance with IEC 60269 and DIN EN 60269 standards. The NH000 form factor and 50A current rating make the 50NHG000B an ideal choice for compact switchgear assemblies where reliable overcurrent protection and space efficiency are equally critical. As a gL-gG class device, it delivers full-range protection from overloads through to prospective short-circuit fault currents, ensuring consistent performance across the complete range of overcurrent conditions encountered in low-voltage power systems.
The 50NHG000B is used extensively in low-voltage switchgear panels, main and sub-distribution boards, motor control centres, and industrial cable feeder circuits. Its NH000 size suits busbar-mounted and DIN-rail-compatible fuse bases, making it straightforward to integrate into both new panel builds and retrofit upgrade projects. Typical deployment environments include manufacturing plants, commercial buildings, data centres, pump stations, HVAC systems, and any installation where dependable branch circuit and feeder protection is required at the 50A level.
The 50NHG000B features a DIN-standard blade contact construction that ensures low contact resistance and consistent mating with NH000-compatible fuse holders and disconnectors. The dual fuse element design provides enhanced current-limiting performance and high breaking capacity, allowing the fuse to safely interrupt high prospective fault currents without damage to surrounding switchgear components. Full compliance with IEC 60269 and DIN EN 60269 guarantees that the 50NHG000B meets internationally recognised safety and performance benchmarks, supporting panel builders and engineers in achieving certified low-voltage assembly standards.
Eaton Bussmann is a globally recognised leader in circuit protection, trusted by OEMs, panel builders, electrical contractors, and consulting engineers across more than 175 countries. Their NH fuse link range is engineered for long service life, dimensional consistency across production batches, and predictable time-current characteristics that simplify selective coordination design. Eaton Bussmann’s rigorous quality management and type-tested product portfolio make them the preferred specification for mission-critical low-voltage distribution infrastructure worldwide.

What does NH size 000 mean in fuse 50NHG000B?
NH size 000 refers to the standardised physical dimension category of the DIN-type fuse link as defined under IEC 60269 and DIN EN 60269. The size 000 designation specifies the blade contact dimensions, overall body length, and the current rating range the fuse can safely accommodate. It is the smallest standard NH size and is commonly used in compact switchgear and distribution boards where space is at a premium.
What does class gL-gG mean for the 50NHG000B?
Class gL-gG is a general-purpose fuse utilisation category defined by IEC 60269. The prefix g indicates that the fuse provides full-range overcurrent protection, capable of safely interrupting any overcurrent from the minimum fusing current up to the maximum rated breaking capacity. The gL designation covers line protection for cables and conductors, while gG extends this to general load protection including motors, transformers, and other electrical equipment in low-voltage installations.
What are the typical applications for the 50NHG000B?
The Eaton Bussmann 50NHG000B 50A NH000 fuse link is used in low-voltage switchgear panels, main and sub-distribution boards, motor control centres, motor feeder circuits, cable feeder protection, and busbar protection in industrial plants, commercial buildings, pump stations, and HVAC systems. Its compact NH000 size makes it well suited for space-constrained panel assemblies.
What standards does the 50NHG000B comply with?
The Eaton Bussmann 50NHG000B is designed and tested in compliance with IEC 60269 and DIN EN 60269, the internationally and European-recognised standards for low-voltage fuses. Compliance with these standards ensures the fuse meets defined requirements for rated current, voltage, breaking capacity, time-current characteristics, and dimensional interchangeability with compatible NH000 fuse bases and holders.
Is the 50NHG000B compatible with standard NH000 fuse bases and holders?
Yes. The 50NHG000B conforms to the NH size 000 blade contact dimensions specified under DIN EN 60269, making it fully dimensionally compatible with standard NH000 fuse bases, fuse disconnectors, and fuse switch disconnectors from Eaton Bussmann and other manufacturers that comply with the same standard.
