Description
The Eaton Bussmann 800NHG3B is a high-performance 800A NH Size 3 Low-Voltage DIN-Type Dual Fuse Link conforming to the gL-gG class under IEC 60269 and DIN EN 60269 standards. Designed for full-range overcurrent protection, the 800NHG3B combines a dual fuse element construction with precision-engineered blade contacts to deliver consistent and reliable fault clearing at rated currents up to 800A. Its NH Size 3 form factor ensures direct interchangeability with compatible DIN-standard fuse bases and switch-disconnectors used across industrial power distribution systems.
The 800NHG3B is ideally suited for deployment in low-voltage switchgear assemblies, main and sub distribution boards, motor control centres, transformer feeders, and cable feeder protection circuits. Its high current rating of 800A makes it particularly appropriate for protecting large power distribution networks in manufacturing plants, commercial buildings, data centres, and infrastructure projects where continuity of supply and equipment protection are critical priorities.
Engineered to DIN-type dimensional standards, the 800NHG3B features a dual fuse element design that enhances current-limiting performance and arc quenching capability, resulting in a high breaking capacity suited to demanding low-voltage applications. Full compliance with IEC 60269 and DIN EN 60269 ensures predictable time-current characteristics, making it straightforward to coordinate with upstream and downstream protective devices in selective protection schemes. The gL-gG classification confirms suitability for protecting both cables and general electrical loads across the full overcurrent range.

What does NH Size 3 mean in the fuse 800NHG3B?
NH Size 3 refers to the standardised physical dimension class of the DIN-type fuse link as defined under IEC 60269 and DIN EN 60269. Size 3 specifies the blade contact dimensions, overall body length, and current rating range of the fuse, ensuring mechanical and electrical interchangeability with all compatible NH Size 3 fuse bases, switch-disconnectors, and fuse carriers from different manufacturers.
What does the gL-gG class mean for the 800NHG3B?
The gL-gG classification is a general-purpose fuse utilisation category defined in IEC 60269. The prefix g indicates full-range breaking capacity, meaning the fuse can interrupt all fault currents from the minimum fusing current up to its rated short-circuit breaking capacity. The gL designation covers cable and line protection while gG extends this to general load protection including motors, transformers, and distribution circuits, making the 800NHG3B suitable for a broad range of low-voltage applications.
What are the typical applications for the Eaton Bussmann 800NHG3B?
The 800NHG3B 800A NH Size 3 dual fuse link is commonly used in low-voltage main switchgear panels, power distribution boards, motor control centres, transformer secondary protection, busbar protection systems, and cable feeder circuits in industrial plants, commercial complexes, data centres, and infrastructure installations where reliable high-current overcurrent protection is essential.
What is the breaking capacity of the 800NHG3B?
As a gL-gG class fuse link compliant with IEC 60269 and DIN EN 60269, the 800NHG3B is rated for high breaking capacity suitable for low-voltage systems up to the voltage rating specified by Eaton Bussmann. For precise breaking capacity values and time-current characteristic curves, please refer to the official Eaton Bussmann datasheet or contact Shansen Enterprises for technical documentation.
Is the 800NHG3B compatible with standard NH Size 3 fuse holders?
Yes, the 800NHG3B is manufactured to DIN-type NH Size 3 dimensional standards, making it fully compatible with standard NH Size 3 fuse bases, in-line fuse holders, and switch-disconnectors that accept Size 3 fuse links from any IEC 60269-compliant manufacturer.
