Fuse link - NH000 UQ gR 63A/690V - ultra-fast 004331026

Fuse links NH000 – fast protection for semiconductors

The NH000 UQ gR 63A/690V fuse link is a component designed to protect electrical circuits, especially semiconductor devices, from the effects of overloads and short circuits. Its ultrafast gR characteristic ensures a rapid response and minimizes the risk of damage. This is crucial in applications where even short-duration overvoltages can lead to costly failures.

Construction and application

The NH000 UQ fuse is designed to operate in alternating current (AC) networks with a rated voltage of up to 690V. Its construction based on IEC 60269-4 standard guarantees reliable operation and safety. The rated current of 63A makes it ideal for protecting circuits with medium power. The top indicator facilitates visual control of the fuse status – after blowing, the indicator clearly signals the need for replacement.

Key features and benefits

• Fast response: The gR characteristic provides ultra-fast protection of semiconductor elements, minimizing the duration of the short circuit and limiting damage.
• High breaking capacity: The short-circuit breaking capacity at 50kA guarantees effective disconnection of the circuit in the event of a serious failure.
• Safety and reliability: Compliance with IEC 60269-4 confirms the high quality of workmanship and compliance with stringent safety standards.
• Easy status identification: The top indicator allows for quick and easy visual assessment of the fuse status without the need for disassembly.
• Reduced power loss: Power loss on the fuse is only 20W, which translates to energy efficiency of the installation.
• Total Joule disconnection: A value of 4,650 A²s indicates the ability to absorb energy during short-circuit disconnection, which affects the durability of the device and the safety of the installation.

It is worth remembering that choosing the right fuse link is crucial for the proper operation of the protection system. NH000 UQ gR 63A/690V is a proven choice for professionals who value reliability and effectiveness in protecting their electrical installations.
