Knife fuse link NH000 double indicator insulated holder gG 80A 500VAC LNH0080MK

Safety and Protection of Electrical Installations

This NH000 blade fuse is a key element protecting electrical circuits from overload and short circuit. Designed to operate at 500V AC, it offers reliable protection for installations in commercial, industrial buildings and energy distribution systems. The double indicator allows for quick visual identification of burnout, making it easier to locate and repair faults.

Construction and Application

The fuse is designed to work with circuits with a rated current of 80A. Manufactured in accordance with IEC 60269, it is characterized by a solid construction and high quality workmanship. Metal insulated grips (IMGL) increase safety, minimizing the risk of electric shock during replacement. The gG characteristic (general protection) makes it ideal for protecting cables and devices against the effects of overloads and short circuits. Power loss at 6.5W at rated current indicates energy efficiency.

Key Features and Benefits

• Fast burnout identification: The double action indicator facilitates diagnosing problems in the electrical installation – for both the installer and the end user.
• Safety of use: Metal insulated grips (IMGL) provide additional protection against electric shock during fuse replacement.
• Versatility of application: Suitable for protecting various electrical circuits in residential, commercial and industrial buildings.
• Compliance with standards: Meets the requirements of IEC 60269, guaranteeing reliable operation and safety of use.
• High short-circuit breaking capacity: The rated short-circuit breaking capacity AC is 120 kA, which ensures effective protection of the installation in the event of a short circuit.
• Energy efficiency: Low power loss (6.5W) translates to lower energy losses in the electrical installation.

Installation and Maintenance

Fuse replacement should be performed by a qualified electrician after disconnecting the power supply. Make sure that the new fuse has appropriate parameters (rated current, characteristic) in accordance with the installation requirements. Regular visual inspection of the fuses allows for quick detection of any damage or burnout.
