Knife fuse link NH00 double indicator non-insulated gG 80A 690VAC LNH00080M6

Safety and reliability of electrical installations

This NH00 fuse link is a key element in protecting electrical circuits. Designed to operate in AC systems up to 690V, it provides effective protection against overloads and short circuits. The operating indicator, in the form of a combined (double) indicator, facilitates quick identification of a blown fuse, minimizing downtime of the installation.

Characteristics and application

The fuse link with gG characteristic (fully delayed) is ideal for protecting circuits that may experience short-term current surges, such as motor starting. This characteristic allows for momentary exceeding of the rated current without unnecessary tripping of the circuit. The rated current of 80A makes this link suitable for installations with medium and high power. The NH000 design ensures compatibility with a wide range of switchgear and fuse boxes.

Advantages for installers and end users

• Fast fault diagnosis: The double operating indicator facilitates the location of a blown fuse – saving time and repair costs.
• Protection against overload and short circuit: Ensures the safety of the electrical installation and connected devices.
• Versatility: Suitable for use in various types of AC installations up to 690V.
• Interference resistance: The gG characteristic minimizes the risk of unnecessary tripping of the circuit when starting motor-driven devices.
• High compactness: Rated short-circuit breaking capacity at 120 kA guarantees effective protection even with high short-circuit currents.
• Simple installation: NH00 knife contacts are easy to replace, simplifying maintenance work.
• Low power loss: With a power loss of 6.8W at the rated current, energy losses in the installation are minimized.

Additionally, it is worth mentioning the dimensions of the link: height 58.5 mm, width 21 mm and depth 79 mm – compact dimensions facilitate installation even in tight spaces. The package contains 3 pieces of the product, which increases convenience and allows you to have a stock.
