Description
The Eaton Bussmann 355NHG03B is a 355A rated, NH size 03, low-voltage DIN-type dual fuse link conforming to the gL-gG protection class as defined by IEC 60269 and DIN EN 60269. Designed for general purpose full-range overcurrent protection, this fuse link combines robust construction with precise current-limiting characteristics, making it a dependable choice for demanding electrical installations that require both line and general load protection in a single compact fuse element.
The 355NHG03B is ideally suited for deployment in low-voltage switchgear assemblies, main and sub-distribution boards, motor control centres, and feeder cable protection circuits. Its 355A rating and NH03 form factor make it particularly well matched to high-current distribution applications in industrial plants, commercial buildings, data centres, and utility infrastructure where protecting expensive downstream equipment and cabling is critical.
Built to DIN-type dimensional standards, the 355NHG03B features a dual fuse element design that delivers a high breaking capacity with accurate time-current characteristics. Full compliance with IEC 60269 and DIN EN 60269 ensures interoperability with standard NH03 fuse holders and bases across major switchgear platforms. The gL-gG classification guarantees full-range protection from overloads through to short-circuit fault currents, eliminating the need for separate overload and short-circuit protective devices in many applications.
Eaton Bussmann is a globally recognised leader in circuit protection, trusted by OEMs, panel builders, electrical contractors, and facility managers across more than 175 countries. Their NH fuse link range is engineered to the highest quality standards, backed by rigorous type testing, and supported by comprehensive technical documentation, ensuring design engineers and procurement teams can specify with complete confidence regardless of the application complexity.

What does NH size 03 mean in fuse 355NHG03B?
NH size 03 refers to the standardised physical dimension category of the DIN-type fuse link. Size 03 defines the blade contact geometry, overall body dimensions, and the current rating range the fuse can safely handle, ensuring mechanical and electrical compatibility with NH03-rated fuse holders, bases, and switch-disconnectors across different manufacturers.
What does class gL-gG mean?
Class gL-gG is a general purpose fuse classification defined under IEC 60269 that provides full-range overcurrent protection for both cables and general electrical loads including motors and transformers in low-voltage installations. The designation indicates the fuse is capable of interrupting all fault currents from the minimum fusing current up to the maximum rated breaking capacity, covering both overload and short-circuit conditions.
What are the typical applications for the 355NHG03B?
The 355NHG03B 355A NH03 fuse link is commonly used in low-voltage switchgear panels, main and sub-distribution boards, motor control centres, feeder cable protection circuits, and transformer secondary protection in industrial manufacturing facilities, commercial buildings, data centres, and utility distribution networks.
Is the 355NHG03B compatible with standard NH03 fuse holders?
Yes. The 355NHG03B conforms to DIN-type NH size 03 dimensional standards per DIN EN 60269, making it fully compatible with standard NH03 fuse holders, bases, and switch-fuse units from major switchgear manufacturers. Always verify the voltage and current ratings of the fuse holder match the application requirements before installation.
