Description
The Eaton Bussmann 500NHG3B is a 500A NH Size 3 Low-Voltage DIN-Type Dual Fuse Link designed to meet the exacting requirements of modern electrical protection systems. Manufactured to class gL-gG under IEC 60269 and DIN EN 60269 standards, this fuse link provides full-range overcurrent protection, safeguarding both cables and connected loads across a wide spectrum of fault conditions. Its robust NH Size 3 blade contact format ensures secure fitment in compatible fuse bases and switch-disconnectors used throughout low-voltage power distribution infrastructure.
The 500NHG3B is widely deployed in low-voltage switchgear assemblies, main and sub-distribution boards, motor control centres (MCCs), and cable feeder protection applications in industrial plants, commercial buildings, and utility installations. Its 500A rating makes it particularly well-suited for protecting large cable runs, bus coupler circuits, transformer secondaries, and high-current motor feeder circuits where dependable overcurrent interruption is critical to system safety and uptime.
As a DIN-type fuse link, the 500NHG3B conforms to standardised dimensional and performance requirements that ensure interoperability with DIN-format fuse holders and switch-fuse units. The dual fuse element design enhances arc-quenching performance and contributes to its high breaking capacity, allowing it to safely interrupt large prospective short-circuit currents without damage to surrounding equipment. Full compliance with IEC 60269 and DIN EN 60269 guarantees consistent, predictable time-current characteristics essential for coordinated protection schemes.

What does NH Size 3 mean in fuse 500NHG3B?
NH Size 3 refers to the standardised physical dimension category 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 the current rating range the fuse link can accommodate, ensuring mechanical and electrical compatibility with NH Size 3 fuse bases, switch-disconnectors, and fuse carriers used in low-voltage switchgear and distribution equipment.
What does class gL-gG mean for the 500NHG3B fuse link?
Class gL-gG is a general-purpose fuse utilisation category defined by IEC 60269 that provides full-range overcurrent protection for both line conductors and general electrical loads. The designation covers protection against overloads as well as short-circuit fault currents, making it suitable for safeguarding cables, distribution circuits, motor feeders, and transformer secondaries in low-voltage installations.
What are the typical applications for the 500NHG3B?
The 500NHG3B 500A NH Size 3 dual 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 facilities, commercial buildings, data centres, and utility power distribution systems.
What standards does the Eaton Bussmann 500NHG3B comply with?
The 500NHG3B complies with IEC 60269 and DIN EN 60269, the internationally recognised standards for low-voltage fuses. These standards define the dimensional, electrical, and time-current performance requirements that ensure safe, reliable, and coordinated overcurrent protection across low-voltage power systems.
