Description
The Eaton Bussmann 425NHG3B is a 425A NH Size 3 Low-Voltage DIN-Type Dual Fuse Link classified as gL-gG under IEC 60269 and DIN EN 60269. Engineered for robust full-range overcurrent protection, this fuse link combines a dual fuse element design with high breaking capacity to safeguard low-voltage electrical circuits against both overload and short-circuit conditions. The NH Size 3 form factor ensures compatibility with standard DIN-type fuse bases and holders widely used across industrial and commercial switchgear installations.
The 425NHG3B is ideally suited for a broad range of low-voltage power distribution applications, including main and sub-distribution boards, low-voltage switchgear panels, motor control centres, motor feeder circuits, transformer secondary protection, and cable feeder protection in industrial plants, commercial buildings, and infrastructure projects. Its 425A rating makes it particularly effective in high-current branch circuits where reliable overcurrent discrimination and fast fault clearance are critical to system uptime and equipment safety.
As a DIN-type NH fuse link, the 425NHG3B conforms to the standardised dimensions and performance requirements defined by DIN EN 60269 and IEC 60269, ensuring dimensional interchangeability with compliant fuse bases across leading panel manufacturers. The dual fuse element construction provides enhanced current-limiting performance and precise time-current characteristics, delivering consistent protection coordination within complex LV distribution systems. Its high breaking capacity ensures safe fault clearance even under prospective short-circuit currents typical in heavy industrial environments.

What does NH Size 3 mean in fuse 425NHG3B?
NH Size 3 refers to the standardised physical dimension class of the DIN-type fuse link as defined by DIN EN 60269 and IEC 60269. Size 3 specifies the blade contact dimensions, overall body length, and the current rating range the fuse can safely accommodate, ensuring correct mechanical and electrical fitment in compatible NH Size 3 fuse bases and switch-disconnectors.
What does class gL-gG mean for the 425NHG3B?
Class gL-gG is a general-purpose fuse classification under IEC 60269 that indicates full-range overcurrent protection capability. The designation covers protection of both cables and general electrical loads — including motors, transformers, and distribution circuits — against overload currents as well as short-circuit fault currents across the full breaking range of the fuse.
What are the typical applications for the Eaton Bussmann 425NHG3B?
The 425NHG3B 425A NH Size 3 dual fuse link is commonly used in low-voltage switchgear panels, main and sub-distribution boards, motor control centres, motor feeder protection, transformer secondary circuits, and cable feeder protection in industrial manufacturing plants, commercial buildings, data centres, and infrastructure installations.
What standards does the 425NHG3B comply with?
The Eaton Bussmann 425NHG3B complies with DIN EN 60269 and IEC 60269, the internationally recognised standards for low-voltage fuses. These standards define the performance, dimensional, and testing requirements that ensure safe and reliable operation and interchangeability with compliant fuse bases and accessories.
What is a dual fuse element design and why does it matter?
A dual fuse element design incorporates two fuse elements within a single fuse link body, providing enhanced current-limiting performance, more precise time-current characteristics, and improved protection coordination compared to single-element designs. This results in more reliable discrimination between overload and short-circuit events, reducing nuisance tripping while ensuring fast fault clearance when required.
