Description
The Eaton Bussmann 355NHG1B is a 355A NH Size 1 Low-Voltage DIN-Type Dual Fuse Link conforming to class gL-gG as defined by IEC 60269 and DIN EN 60269. Engineered for dependable full-range overcurrent and short-circuit protection, this fuse link combines a robust dual fuse element design with standardized NH Size 1 blade contacts to ensure safe, consistent performance in demanding low-voltage electrical installations. The gL-gG classification confirms its suitability for protecting both cables and general electrical loads across the complete current range from overload through to maximum fault conditions.
The 355NHG1B is widely specified in low-voltage switchgear assemblies, main and sub distribution boards, motor control centres (MCCs), motor feeder circuits, transformer secondary protection, and cable feeder protection in industrial plants, commercial buildings, utilities, and infrastructure projects. Its 355A rating makes it particularly well suited for high-current feeder circuits where reliable disconnection under fault conditions is critical to protecting downstream equipment and personnel.
Technically, the 355NHG1B features a DIN-standardized NH Size 1 form factor, ensuring drop-in compatibility with NH Size 1 fuse holders and bases from leading switchgear manufacturers. The dual fuse element construction enhances arc quenching performance, delivering a high breaking capacity that meets the stringent requirements of IEC 60269 and DIN EN 60269. The fuse link’s low pre-arcing I²t and total operating I²t values minimise thermal stress on connected equipment during fault clearance, while the clear current rating and indicator design simplify maintenance and inspection routines.

What does NH Size 1 mean in the 355NHG1B fuse link?
NH Size 1 refers to the standardized physical dimension class of the DIN-type fuse link as defined under IEC 60269 and DIN EN 60269. Size 1 specifies the blade contact geometry, overall body dimensions, and the current rating range the fuse can safely accommodate. It ensures interchangeability and drop-in compatibility with all NH Size 1 fuse holders, bases, and switch-disconnectors from compliant switchgear manufacturers.
What does the gL-gG class mean for the 355NHG1B?
The gL-gG classification is a general-purpose fuse utilization category defined by IEC 60269. The lowercase ‘g’ prefix indicates full-range breaking capacity, meaning the fuse can safely interrupt currents from the minimum fusing current all the way up to the maximum rated short-circuit current. The ‘L’ designates protection for cables and lines, while ‘G’ denotes general application coverage including motors, transformers, and mixed loads. Together, gL-gG confirms the 355NHG1B provides comprehensive overcurrent and short-circuit protection for a wide variety of low-voltage applications.
What are the typical applications for the Eaton Bussmann 355NHG1B?
The 355NHG1B 355A NH1 fuse link is commonly used in low-voltage main and sub distribution boards, LV switchgear panels, motor control centres, motor and transformer feeder circuits, busbar protection, and cable feeder protection in industrial manufacturing facilities, commercial buildings, data centres, utilities, and infrastructure projects requiring reliable high-current overcurrent protection.
What standards does the 355NHG1B comply with?
The Eaton Bussmann 355NHG1B complies with IEC 60269 and DIN EN 60269, the internationally and European harmonized standards governing low-voltage fuses. Compliance with these standards ensures the fuse link meets defined requirements for rated current, breaking capacity, power dissipation, temperature rise, and dimensional interchangeability.
