Description
The Eaton Bussmann 63NHG00B is a 63A NH size 00 Low-Voltage DIN-Type Dual Fuse Link designed for full-range overcurrent protection in demanding industrial and commercial electrical installations. Rated at 63 amperes and classified as gL-gG under IEC 60269 and DIN EN 60269 standards, this fuse link delivers dependable protection for both cables and general electrical loads. Its NH size 00 form factor ensures compatibility with standard DIN-type fuse bases and holders widely used across low-voltage power distribution systems.
The 63NHG00B is ideally suited for a broad range of low-voltage applications including main and sub distribution boards, motor control centres, motor feeder circuits, cable feeder protection, industrial switchgear panels, and commercial power distribution assemblies. Its gL-gG classification makes it an excellent choice for protecting cables, busbars, transformers, and general-purpose loads against overload and short-circuit conditions in installations up to 400V AC and beyond.
Engineered to DIN-type dimensional standards, the 63NHG00B features a dual fuse element design that enhances current-limiting performance and ensures high breaking capacity under fault conditions. Full compliance with IEC 60269 and DIN EN 60269 guarantees predictable and consistent overcurrent protection characteristics, making it straightforward to coordinate with upstream and downstream protective devices. The precision-manufactured fuse elements provide accurate pre-arcing and total operating time-current characteristics essential for discrimination in complex distribution networks.
Eaton Bussmann is a globally recognised leader in circuit protection, trusted by OEMs, panel builders, electrical contractors, and facility managers across more than 175 countries. Their NH fuse link range is manufactured to stringent quality standards, offering exceptional reliability, long service life, and consistent performance that minimises unplanned downtime in critical electrical infrastructure.

What does NH size 00 mean in fuse 63NHG00B?
NH size 00 refers to the standardised physical dimension of the DIN-type fuse link body and blade contacts. Size 00 is the smallest in the NH fuse family and defines the contact blade geometry, overall dimensions, and the current rating range the fuse can safely handle, ensuring interchangeability with all compatible NH size 00 fuse bases and switch-disconnectors.
What does class gL-gG mean for the 63NHG00B?
Class gL-gG is a general-purpose fuse utilisation category defined under IEC 60269 and DIN EN 60269. The prefix g indicates full-range breaking capacity, meaning the fuse can safely interrupt all overcurrents from the minimum fusing current up to the rated breaking capacity. The gL designation covers cable and line protection while gG covers general electrical loads, so a gL-gG fuse provides comprehensive protection for cables, motors, transformers, and general distribution circuits against both overload and short-circuit faults.
What are the typical applications for the Eaton Bussmann 63NHG00B?
The 63NHG00B 63A NH00 fuse link is widely used in low-voltage switchgear and controlgear assemblies, main and sub distribution boards, motor control centres, motor feeder and branch circuit protection, cable feeder protection, busbar protection, and general power distribution panels in industrial plants, commercial buildings, and infrastructure projects.
What voltage rating is the 63NHG00B suitable for?
The Eaton Bussmann 63NHG00B NH00 gL-gG fuse link is rated for use in low-voltage AC systems, typically up to 500V AC, making it suitable for standard 400V three-phase and 230V single-phase industrial and commercial distribution networks. Please refer to the official Eaton Bussmann datasheet for complete electrical ratings and derating guidelines.
