Description
The Eaton Bussmann 125NHG00B is a 125A rated, NH size 00, Low-Voltage DIN-Type NH Dual Fuse Link belonging to the gL-gG class as defined under DIN EN 60269 and IEC 60269. Engineered to deliver full-range overcurrent protection, the 125NHG00B combines a dual fuse element design with robust blade contacts to ensure precise, consistent operation across its entire current range. Its compact NH size 00 form factor makes it ideal for integration into standard DIN-compatible fuse bases and switch-disconnectors commonly found in modern low-voltage electrical systems.
The 125NHG00B is widely specified in low-voltage switchgear panels, main and sub distribution boards, motor control centres (MCCs), and industrial feeder circuits where dependable cable and equipment protection is critical. It is equally suited to protecting transformer secondaries, capacitor banks, and busbar trunking systems in commercial buildings, manufacturing facilities, infrastructure projects, and utility substations. The 125A rating makes it a preferred choice for feeder circuits supplying medium-sized motor groups, HVAC systems, and process equipment in industrial environments.
Technically, the 125NHG00B benefits from a DIN-standard blade contact construction that ensures low contact resistance and reliable seating in NH fuse carriers. The dual fuse element design enhances arc-quenching performance and contributes to its high breaking capacity, allowing the fuse to safely interrupt fault currents typical of low-voltage distribution networks. Full compliance with DIN EN 60269 and IEC 60269 guarantees interoperability with internationally standardised fuse holders and switch-disconnectors, simplifying panel design and maintenance across global and locally sourced equipment.
Eaton Bussmann is one of the world’s most trusted names in circuit protection, with decades of engineering excellence serving OEM panel builders, electrical contractors, and facilities maintenance teams across more than 175 countries. The Bussmann series NH fuse range is backed by rigorous quality assurance, traceable manufacturing standards, and comprehensive technical support, giving design engineers and procurement teams the confidence that every fuse link will perform precisely as specified throughout its service life.

What does NH size 00 mean in fuse 125NHG00B?
NH size 00 refers to the standardised physical dimension category of the DIN-type fuse link as defined under DIN EN 60269 and IEC 60269. Size 00 specifies the blade contact dimensions, overall body length, and the current rating range the fuse can accommodate, ensuring mechanical and electrical compatibility with NH size 00 fuse carriers, switch-disconnectors, and fuse bases from any compliant manufacturer.
What does class gL-gG mean for the 125NHG00B?
Class gL-gG is a general-purpose fuse utilisation category defined by IEC 60269. The lowercase g indicates full-range breaking capacity, meaning the fuse can interrupt all overcurrents from its minimum fusing current up to its maximum rated breaking capacity. The gL designation covers cable and line protection while gG covers general application protection including motors, transformers, and mixed loads, making the 125NHG00B suitable for a broad range of low-voltage distribution and feeder applications.
What are the typical applications for the Eaton Bussmann 125NHG00B?
The 125NHG00B 125A NH fuse link is commonly used in low-voltage switchgear panels, main and sub distribution boards, motor control centres, transformer secondary protection, HVAC feeder circuits, and cable feeder protection in industrial plants, commercial buildings, and infrastructure projects. Its 125A rating and NH size 00 form factor suit it to medium-capacity feeder and branch circuit protection across a wide range of electrical installations.
Is the 125NHG00B compatible with standard NH00 fuse holders?
Yes. The 125NHG00B is manufactured to DIN EN 60269 and IEC 60269 dimensional standards for NH size 00, ensuring full mechanical and electrical compatibility with any compliant NH size 00 fuse carrier, switch-disconnector, or fuse base, regardless of the manufacturer. Always verify the fuse holder’s current and voltage ratings before installation.
