Description
The Eaton Bussmann 400NHG2B is a 400A NH size 2 low-voltage DIN-type dual fuse link conforming to the gL-gG class as defined under IEC 60269 and DIN EN 60269. Engineered for full-range overcurrent protection, this fuse link combines a robust dual fuse element design with precision-calibrated characteristics to deliver consistent, predictable protection across a wide range of fault conditions in low-voltage power systems.
The 400NHG2B is ideally suited for deployment in low-voltage switchgear panels, distribution boards, motor control centres, and bus bar systems operating in industrial plants, commercial buildings, and infrastructure facilities. Its 400A rating makes it particularly effective for protecting heavy-duty cable feeders, transformer secondaries, and motor branch circuits where sustained load currents are high and short-circuit fault levels demand a fuse with a high interrupting rating.
As a DIN-type NH fuse link, the 400NHG2B features standardised blade contacts that ensure secure, low-resistance seating in compatible NH size 2 fuse bases and switch-fuse disconnectors. The dual fuse element construction enhances arc quenching efficiency and contributes to the fuse’s high breaking capacity, while full compliance with IEC 60269 and DIN EN 60269 guarantees interoperability with internationally standardised switchgear components. The gL-gG classification confirms its capability for general-purpose line and load protection across the full overcurrent range from overload through to maximum prospective short-circuit current.
Eaton Bussmann is a globally recognised leader in circuit protection, trusted by OEMs, panel builders, electrical contractors, and plant 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 technical documentation. Specifying Eaton Bussmann products gives engineers and procurement teams confidence in long-term availability, consistent performance, and full regulatory compliance for both new installations and retrofit projects.

What does NH size 2 mean in fuse 400NHG2B?
NH size 2 refers to the standardised physical dimension category of the DIN-type fuse link as defined under IEC 60269 and DIN EN 60269. The size 2 designation 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 2 fuse bases, switch-disconnectors, and fuse carriers from any compliant manufacturer.
What does class gL-gG mean?
The gL-gG classification is a general-purpose fuse utilisation category defined by IEC 60269. The lowercase g indicates full-range breaking capacity, meaning the fuse can interrupt currents from the minimum fusing current up to the maximum rated breaking capacity. The L and G suffixes denote protection of cables and general electrical loads respectively, making the 400NHG2B suitable for protecting feeders, distribution circuits, motor branch circuits, and transformer secondaries in low-voltage installations.
What are the typical applications for the 400NHG2B?
The 400NHG2B 400A NH size 2 dual fuse link is commonly used in low-voltage main and sub-distribution switchgear panels, motor control centres, bus bar protection, cable feeder circuits, transformer secondary protection, and industrial power distribution boards in manufacturing plants, commercial complexes, data centres, and infrastructure projects where reliable overcurrent protection at 400A is required.
Is the 400NHG2B compatible with standard NH2 fuse holders and bases?
Yes. The 400NHG2B is a DIN-type NH size 2 fuse link with standardised blade contacts per IEC 60269 and DIN EN 60269, making it directly compatible with any compliant NH size 2 fuse base, switch-fuse disconnector, or fuse carrier designed for the NH2 form factor, regardless of manufacturer.
