Knife fuse link NH000 double indicator non-insulated holder gG 80A 500VAC LNH0080M

Safety and electrical installation protection

NH000 blade fuse link is an element used to protect electrical circuits against overload and short circuit. Model LNH0080M, with a rated current of 80A and a voltage of 500VAC, is designed for use in industrial and commercial installations where reliable protection is required. The double indicator allows for quick visual identification of a blown fuse, making it easier to locate and repair faults.

Construction and application

The fuse link is manufactured in accordance with IEC 60269 standard, and its NH000 type construction ensures compatibility with a wide range of fuse holders. The gG characteristic (main protection) means that this fuse link provides full protection against the effects of overloads and short circuits. Lack of handle insulation requires special caution during replacement – the circuit must be de-energized. The combined (double) operating indicator is a practical solution for installers, allowing easy checking of the fuse link status without having to remove it from the circuit.

Key features and benefits

• High short-circuit breaking capacity: The rated short-circuit breaking capacity Icn is 120 kA, which guarantees effective protection of the installation even in the event of high short-circuit currents.
• Fast burnout identification: The double operating indicator facilitates quick location of the damaged fuse, minimizing installation downtime.
• Versatility: The fuse link fits standard NH000 fuse holders, making replacement and modernization of existing installations easier.
• Reliability: Made of high-quality materials, it ensures long-lasting and reliable operation.
• Status transparency: The operating indicator allows for a quick assessment of whether the fuse link needs to be replaced without the need for disassembly.
• Optimal power loss: At a rated current of 80A, the power loss is 6.5W – a good result in this class of devices.

It is important to select the correct fuse link for the protected circuit, taking into account the characteristics of the loads and the requirements of safety standards. Choosing the appropriate current value and gG characteristic will ensure effective protection of the electrical installation against damage caused by overloads or short circuits.
