Fuse insert NH1 125A GG 800V combination Etipo 004184489 time-delay

NH1 fuse insert by Etipo rated 125 A with GG (gG) characteristic and 800 V voltage rating. This time‑delay combination fuse insert is intended for protection of electrical circuits, switchgear and distribution boards against overloads and short circuits in industrial and commercial environments. It is designed to fit NH1 fuse holders and provides selective protection where both overload and short‑circuit clearing are required.

Advantages

The NH1 125 A GG time‑delay fuse insert offers coordinated, reliable protection with a gG characteristic suitable for general-purpose circuit protection. The time‑delay design tolerates temporary inrush currents while still interrupting sustained overloads and short circuits. Its construction supports secure mounting in NH fuse holders and integration into standard switchgear panels, ensuring stable electrical contact and predictable operation under rated conditions.

Suitable for

• Protection of feeders and distribution circuits in industrial switchgear
• Protections in commercial electrical installations and distribution boards
• Circuit protection where motor or transformer inrush currents require time‑delay operation
• Applications requiring NH1 size fuses with 125 A rating and general‑purpose (gG) behavior

Key specifications

• Rated current: 125 A
• Voltage rating: 800 V
• Characteristic: gG (general purpose, time‑delay)
• Fuse size: NH1 (compact NH cartridge format)
• Type: combination/time‑delay fuse insert for NH fuse holders

How to use

Install the fuse insert into a compatible NH1 fuse holder or switchgear compartment that accepts NH cartridges according to the panel manufacturer’s instructions. Ensure the circuit is de‑energized before mounting or replacing the fuse insert. Verify appropriate torque and contact surfaces to achieve reliable electrical connection. After installation, restore power and confirm normal operation; replace the insert with the same type and rating when clearing a fault.

Usage recommendations

Select this NH1 125 A gG time‑delay fuse insert when you need general‑purpose protection with discrimination against short circuits and tolerance for temporary inrush currents. For correct protection selectivity and safety, coordinate with upstream and downstream protective devices and follow local electrical codes and equipment manufacturer guidelines.
