Knife fuse link NH000 double indicator non-insulated holder gG 20A 500VAC LNH0020M

Installation safety and quick problem identification

NH000 fuse link with a double tripping indicator is a reliable protection for electrical circuits. Designed to operate at 500V AC and a rated current of 20A, it provides effective protection against overloads and short circuits. The construction with gG characteristic guarantees delayed tripping during short-term current surges, which is particularly important for devices with motors or other elements with high starting current.

Construction and application

NH000 fuse link is a basic protection element in electrical installations. Its construction, compliant with IEC 60269 standard, ensures compatibility with dedicated fuse holders. The double tripping indicator facilitates quick identification of a blown fuse – it is not necessary to remove the fuse link to check its status. Lack of handle insulation requires special caution during replacement.

Key features and benefits

• gG characteristic: Allows for momentary current exceedances without unnecessary tripping, which is important for devices with motors or transformers.
• Double tripping indicator: Enables quick visual control of the fuse status without having to remove it from the circuit – saving time and increasing safety.
• Rated AC voltage 500V: Intended for a wide range of applications in electrical installations.
• Rated current 20A: Suitable for protecting circuits with medium power consumption.
• Rated short-circuit breaking capacity 80kA: Provides effective protection against the effects of short circuits with high energy.
• Size NH000: Standard fuse link size, ensuring wide availability and compatibility with existing installations.
• Low power loss (2.3W): Minimizes energy losses in the circuit, which translates into operational savings.

Installation and operation

Replacing the fuse link should be carried out only by a qualified electrician, after disconnecting the power supply. Make sure that the new fuse link has the same parameters as the blown one (rated current, characteristic). Due to the lack of handle insulation, special care should be taken during assembly and replacement – use appropriate insulated tools. The set includes 3 pieces in the package, allowing you to have a spare.
