Description
The Eaton Bussmann 40NHG02B is a 40A, NH size 02, Low-Voltage DIN-Type Dual Fuse Link classified gL-gG under IEC 60269 and DIN EN 60269. Engineered for dependable full-range overcurrent protection, it combines robust construction with a dual fuse element design to safeguard cables, busbars, and connected equipment in demanding low-voltage environments. The 40NHG02B is manufactured to Eaton Bussmann’s exacting quality standards, ensuring consistent performance across its full rated current of 40A and high fault-current interrupting capacity.
The 40NHG02B is ideally suited for a wide range of low-voltage power distribution applications. These include LV switchgear assemblies, main and sub-distribution boards, motor control centres (MCCs), motor feeder circuits, transformer secondary protection, and cable feeder protection in both industrial plants and commercial buildings. Its gL-gG classification makes it equally effective for protecting cables against overloads and short circuits as well as safeguarding general-purpose loads such as motors, heating elements, and lighting circuits.
Technically, the 40NHG02B features a DIN-type blade contact (knife contact) construction conforming to the NH size 02 dimensional standard, ensuring interchangeability within correctly rated NH fuse bases and switch-disconnectors. The dual fuse element design enhances current limitation and interrupting performance, providing a high breaking capacity that meets the demanding fault levels encountered in modern low-voltage networks. Full compliance with DIN EN 60269 and IEC 60269 guarantees that the fuse meets internationally recognized safety and performance benchmarks for general-purpose fuse links.

What does NH size 02 mean in fuse 40NHG02B?
NH size 02 refers to the standardized physical dimension of the DIN-type fuse link blade contacts as defined in DIN EN 60269 and IEC 60269. Size 02 determines the specific blade contact dimensions and fits into NH size 02 fuse bases or switch-disconnectors. It also defines the current rating range the fuse link can safely handle, distinguishing it from smaller sizes such as NH00 or NH01 and larger sizes such as NH03 or NH1. Using the correct NH size is essential for safe mechanical and electrical interchangeability within the switchgear assembly.
What does class gL-gG mean in the context of the 40NHG02B?
Class gL-gG designates a general-purpose, full-range fuse per IEC 60269. The prefix “g” indicates that the fuse provides full-range overcurrent protection, meaning it can interrupt fault currents from the minimum fusing current up to its rated breaking capacity. “L” denotes protection of cables and conductors against overload and short circuit, while “G” denotes general application including protection of motors, transformers, and other general loads. The 40NHG02B therefore offers comprehensive overcurrent protection suitable for most low-voltage distribution and feeder applications.
What are the typical applications for the Eaton Bussmann 40NHG02B?
The 40NHG02B 40A NH size 02 dual fuse link is commonly used in low-voltage switchgear panels, main and sub-distribution boards, motor control centres, cable feeder protection, transformer secondary circuits, and busbar protection in industrial manufacturing plants, commercial buildings, infrastructure projects, and utility substations. Its gL-gG classification makes it suitable for protecting both the wiring system and general-purpose connected loads across a broad range of industrial and commercial electrical installations.
Is the 40NHG02B interchangeable with other NH02 fuse links?
Yes, provided the replacement fuse link is also rated NH size 02 and is compatible in terms of voltage rating, current rating, and fuse base design. The NH size 02 blade contact dimensions are standardized under DIN EN 60269 and IEC 60269, enabling interchangeability between compliant fuse links from different manufacturers within the same NH02 fuse base or switch-disconnector. However, always verify that the replacement fuse link’s rated current, breaking capacity, and characteristics are appropriate for the specific application and the ratings of the installed fuse holder.
