NH Fuse Links – Reliable Installation Protection

The NH000 gG 20A/500V fuse link is an element used to protect electrical installations from the effects of overloads and short circuits. It is an industrial component, characterized by high reliability and compliance with applicable standards. This fuse link, thanks to its time-delay characteristic (gG), allows for short-term exceeding of the rated current without disconnecting the circuit – which is particularly important when starting devices with motors or other elements generating high inrush current.

Construction and Application

The NH000 fuse link is made of high-quality materials, such as steatite (body) and silver-plated brass (knife contacts). The use of quartz sand with a special granulation inside the body ensures a high short-circuit breaking capacity, reaching 120kA at 500V AC. Therefore, in the event of a failure, the fuse link effectively interrupts the circuit, protecting the remaining elements of the installation from damage. A combined-type operation indicator (double) – both a red eye in the central part of the ceramic body and a springy plate on the top cover – ensures easy and quick identification of a blown fuse.

Key Features and Benefits

• gG characteristic: Provides protection against overloads and short circuits, allowing for temporary exceeding of the rated current without unnecessary disconnection of the circuit. This is an ideal solution for devices with motors or other loads with high inrush current.
• High short-circuit breaking capacity (120kA): Guarantees effective interruption of the circuit in the event of serious failures, minimizing the risk of damage to the installation and danger to people.
• Double operation indicator: Facilitates quick identification of a blown fuse, reducing installation downtime and facilitating servicing.
• Made of high-quality materials: Steatite body and silver-plated knife contacts ensure durability and reliable operation even in harsh operating conditions.
• Compliance with IEC 60269-1 and IEC 60269-2 standards: Confirms the safety and quality of the product, guaranteeing its correct operation in accordance with industry requirements.
• Rated current of 20A at 500V AC: Allows you to match the fuse link to the specific needs of the electrical installation.
• Power loss Pd of 2.7W: Indicates relatively low energy losses during fuse operation.

It is important to select the correct fuse link for the parameters of the protected electrical installation. Incorrect selection may result in ineffective protection or unnecessary disconnection of the circuit.
