Description
The Eaton Bussmann 125NHG01B is a 125A NH size 01 low-voltage DIN-type dual fuse link conforming to class gL-gG under IEC 60269 and DIN EN 60269 standards. Engineered for full-range overcurrent and short-circuit protection, the 125NHG01B features a dual fuse element construction within a robust NH01 blade-contact body, making it a dependable choice for modern low-voltage electrical systems demanding consistent and predictable protective performance.
The 125NHG01B is ideally suited for deployment in low-voltage switchgear assemblies, main and sub-distribution boards, motor control centres, motor feeder circuits, and cable feeder protection applications across industrial manufacturing facilities, commercial buildings, data centres, and infrastructure projects. Its 125A rating and NH01 form factor make it a standard fit for panel builders designing systems within the 63A to 160A protection band.
As a DIN-type NH fuse link, the 125NHG01B offers a high breaking capacity that safely interrupts fault currents well beyond the rated load current, limiting let-through energy and protecting downstream equipment and wiring. The dual fuse element design enhances current-limiting performance and arc extinction reliability. Full compliance with IEC 60269 and DIN EN 60269 ensures interoperability with NH01-rated fuse holders and switch-disconnectors from leading manufacturers, giving panel builders and engineers confidence in system-level coordination.
Eaton Bussmann is a globally recognised leader in circuit protection, trusted by OEMs, panel builders, electrical contractors, and consulting engineers across more than 100 countries. Their NH fuse link range is manufactured to stringent quality standards, backed by decades of application engineering expertise, and supported by comprehensive documentation for system design and regulatory compliance.

What does NH size 01 mean in fuse 125NHG01B?
NH size 01 refers to the standardized physical dimension category of the DIN-type fuse link as defined under IEC 60269 and DIN EN 60269. Size 01 specifies the blade contact dimensions, overall body length, and the current rating range the fuse can safely accommodate, ensuring mechanical and electrical interchangeability with compatible NH01 fuse holders and switch-disconnectors.
What does class gL-gG mean for the 125NHG01B?
Class gL-gG is a general-purpose fuse utilization category per IEC 60269 that provides full-range overcurrent protection, covering both overload and short-circuit conditions. The gL designation relates to cable and line protection while gG denotes general load protection, making the 125NHG01B suitable for safeguarding cables, transformers, motors, and general distribution circuits in low-voltage installations.
What are the typical applications for the 125NHG01B?
The 125NHG01B 125A NH01 dual fuse link is used in low-voltage switchgear panels, main and sub-distribution boards, motor control centres, motor feeder circuits, and cable feeder protection systems in industrial plants, commercial buildings, infrastructure projects, and data centres where reliable overcurrent and short-circuit protection is required.
Is the 125NHG01B compatible with standard NH01 fuse holders?
Yes. The 125NHG01B conforms to the NH size 01 dimensional standard under IEC 60269 and DIN EN 60269, making it mechanically and electrically compatible with all standard NH01-rated fuse holders, fuse bases, and switch-disconnectors from major manufacturers designed to accept NH01 fuse links.
