Mersen NH0GG50V63 Fusible gG Gr.0 AC500V 63A sfü Combinador de indicadores

For demanding low-voltage distribution circuits, the Mersen NH0GG50V63 fuse link delivers precise protection where standard fuses fall short. Its gG operating class ensures full-range breaking capacity, safeguarding cables and conductors against both overloads and short-circuits up to 120 kA. The NH0 size fits compact fuse bases, while the combined indicator provides clear visual status at a glance.

Highlights

• Rated current 63 A, AC 500 V for industrial power systems
• gG class: reliable protection for general-purpose applications
• High breaking capacity of 120 kA for severe fault conditions
• Dual indicator (combined) shows operation status clearly
• Ceramic body with blade contacts for NH fuse bases
• Complies with IEC 60269 for safety and interchangeability

In daily use

Install this fuse link in NH0 fuse bases within distribution boards or motor control centers. The blade contacts ensure a secure, low-resistance connection, while the ceramic body withstands thermal and mechanical stress. The combined indicator changes state upon operation, allowing quick identification of a blown fuse without removing it. Suitable for 50/60 Hz AC networks, it protects feeders, motors, and other critical loads.
