Description
The Eaton Bussmann 200NHG1B is a high-performance low-voltage DIN-type NH dual fuse link rated at 200A in NH size 1, conforming to the gL-gG protection class as defined under IEC 60269 and DIN EN 60269. Engineered for full-range overcurrent protection, the 200NHG1B safeguards both cables and connected electrical loads against overloads and short-circuit faults in low-voltage power distribution systems. Its dual fuse element construction provides consistent, predictable performance across a wide range of fault current levels, making it a trusted choice for demanding industrial and commercial applications.
The 200NHG1B is widely deployed in low-voltage switchgear assemblies, main and sub-distribution boards, motor control centres (MCCs), and cable feeder circuits in industrial plants, commercial complexes, and utility installations. Its 200A rating makes it particularly well suited for protecting outgoing feeders, transformer secondaries, bus coupler circuits, and large motor branch circuits where reliable overcurrent coordination is critical to system uptime and personnel safety.
As a DIN-type NH fuse link, the 200NHG1B complies fully with IEC 60269 and DIN EN 60269, ensuring dimensional interchangeability with standard NH size 1 fuse bases and switch-disconnectors. The dual fuse element design delivers high breaking capacity, enabling the fuse to safely interrupt high prospective short-circuit currents without damage to surrounding equipment. The gL-gG classification confirms full-range protection capability, meaning the fuse operates across all overcurrent levels from small sustained overloads to maximum prospective fault currents, eliminating the need for supplementary back-up protection in most standard LV applications.
Eaton Bussmann is a globally recognised leader in circuit protection, with decades of engineering expertise trusted by OEMs, panel builders, electrical contractors, and system integrators worldwide. Eaton Bussmann fuse links are manufactured to exacting quality standards, offering consistent time-current characteristics, robust construction, and long service life even in thermally demanding environments. Specifying Eaton Bussmann products such as the 200NHG1B gives engineers and procurement teams confidence in product traceability, technical support, and availability of coordinated protection accessories.

What does NH size 1 mean in fuse 200NHG1B?
NH size 1 refers to the standardized physical dimension category of the DIN-type fuse link as defined under IEC 60269 and DIN EN 60269. Size 1 specifies the blade contact dimensions, overall body length, and the current rating range the fuse can accommodate, ensuring dimensional interchangeability with all compliant NH size 1 fuse bases and switch-fuse disconnectors from any manufacturer conforming to the same standard.
What does class gL-gG mean?
Class gL-gG is a general-purpose fuse utilization class defined under IEC 60269 that provides full-range overcurrent protection for cables and general electrical loads including motors, transformers, and distribution circuits in low-voltage installations. The prefix g denotes full-range breaking capacity, L indicates line protection, and G indicates general application protection, meaning the fuse can interrupt all overcurrent levels from small sustained overloads through to maximum prospective short-circuit currents.
What are the typical applications for the 200NHG1B?
The Eaton Bussmann 200NHG1B 200A NH size 1 fuse link is used in low-voltage switchgear panels, main and sub-distribution boards, motor control centres, transformer secondary protection, bus coupler circuits, and cable feeder protection in industrial manufacturing plants, commercial buildings, infrastructure projects, and utility distribution installations.
What standards does the 200NHG1B comply with?
The 200NHG1B complies with IEC 60269 and DIN EN 60269, the internationally recognised standards for low-voltage fuses. Compliance with these standards guarantees consistent time-current characteristics, dimensional interchangeability with NH size 1 fuse holders, and verified high breaking capacity suitable for use in modern low-voltage power distribution systems.
