Description
The Eaton Bussmann 250NHG03B is a 250A NH size 03 low-voltage DIN-type dual fuse link classified gL-gG in accordance with IEC 60269 and DIN EN 60269. Designed to provide full-range overcurrent protection, this fuse link combines a compact NH03 blade-contact form factor with a dual fuse element construction, making it a dependable and precise protective device for demanding low-voltage power distribution systems. Its 250A current rating makes it suited for high-current circuits where both overload and short-circuit protection are critical.
The 250NHG03B is widely deployed in low-voltage switchgear assemblies, main and sub-distribution boards, motor control centres, motor feeders, transformer secondary circuits, and cable feeder protection in industrial plants, commercial buildings, data centres, and infrastructure projects. Its gL-gG classification ensures it protects both the cable and the connected load across the full range of overcurrent conditions, from sustained overloads to high prospective short-circuit faults.
As a DIN-type NH fuse link, the 250NHG03B conforms to standardised blade-contact dimensions ensuring interchangeability with compatible NH03 fuse bases and switch-disconnectors. The dual fuse element design enhances arc-quenching performance and ensures high breaking capacity, enabling the fuse to safely interrupt large fault currents while limiting let-through energy to protect downstream equipment. Full compliance with IEC 60269 and DIN EN 60269 guarantees consistent performance, predictable time-current characteristics, and suitability for type-tested switchgear assemblies worldwide.

What does NH size 03 mean in fuse 250NHG03B?
NH size 03 refers to the standardised physical dimension class of the DIN-type fuse link as defined under IEC 60269 and DIN EN 60269. Size 03 specifies the blade contact dimensions, overall length, and the current rating range the fuse can accommodate, and it determines compatibility with NH03 fuse bases, switch-fuse units, and fuse switch-disconnectors designed for that size class.
What does class gL-gG mean?
Class gL-gG is a general purpose fuse utilisation category defined by IEC 60269 that provides full-range overcurrent protection. The lowercase g indicates the fuse is capable of breaking any current from the minimum fusing current up to the rated breaking capacity. The L and G designators refer to protection of cables and conductors as well as general purpose load protection, covering both sustained overloads and high prospective short-circuit fault currents in low-voltage installations.
What are the typical applications for the 250NHG03B?
The 250NHG03B 250A NH03 gL-gG dual fuse link is used in low-voltage switchgear panels, main and sub-distribution boards, motor control centres, motor and transformer feeder circuits, and cable feeder protection in industrial manufacturing plants, commercial buildings, infrastructure projects, and data centres where reliable full-range overcurrent protection at 250A is required.
What is the breaking capacity of the 250NHG03B?
The 250NHG03B is a high breaking capacity fuse link designed to safely interrupt high prospective short-circuit currents in low-voltage systems in accordance with IEC 60269 and DIN EN 60269. For exact breaking capacity values and time-current characteristic curves, refer to the Eaton Bussmann product datasheet or contact Shansen Enterprises for technical documentation.
