Ultra-fast fuse link D02 UQ GR 63A/400V 004312005

Ultra-fast protection of installations and semiconductor devices

The D02 UQ gR 63A/400V fuse insert is a protective element designed to protect electrical circuits from the effects of short circuits and overloads. It performs particularly well in applications where a quick response to overvoltages is crucial, protecting sensitive semiconductor components. Its construction and characteristics ensure reliable operation in installations with a rated voltage of up to 400V.

Construction and application

The fuse insert from the Ultra-Quick series by ETI Polam, made of high-quality materials, guarantees durability and stability of parameters. The "gR" designation indicates its intended use for protecting power electronic components - diodes, thyristors and other components sensitive to overvoltages. Size D02 ensures compatibility with a wide range of standard fuse holders. Therefore, replacing a used insert is simple and does not require modification of the installation.

Key features and benefits

• Fast response: The gR characteristic provides an ultra-fast response to short circuits, minimizing the risk of damage to protected devices. This is particularly important in electronics, where even a short-term overvoltage can cause serious failures.
• Protection of semiconductor components: The specially selected characteristic provides optimal protection for diodes, thyristors and other sensitive components.
• Versatility: Rated current of 63A and rated voltage of 400V (also 250V DC) allow the insert to be used in various electrical installations.
• High quality workmanship: ETI Polam is a renowned manufacturer known for the high quality of its products - a guarantee of reliability and long-term operation.
• Easy identification: The copper color of the housing makes it easy to identify the insert with a rated current of 63A.
• Compliance with standards: The insert meets the requirements of IEC 60269-4 standard, which confirms its safety and effectiveness.

It is important to select the correct fuse insert for a specific application - too high a rated current may result in lack of protection, and too low - frequent tripping of the protection.
