Ultra-fast fuse link D01 UQ GR 4A/400V 004311002

Ultra-fast fuse link – protection for sensitive circuits

The D01 UQ 4A/400V fuse link is a protective element designed to protect electrical circuits from the effects of overloads and short circuits. Its construction and time-current characteristics make it particularly recommended for applications requiring a rapid response, such as protecting semiconductor elements. A rated current of 4A and a voltage of 400V make it a universal solution in many installations.

Characteristics and application

The fuse link with the gR designation (according to IEC 60269 standard) is characterized by high selectivity and fast disconnection speed. This means that it reacts very quickly to sudden current increases, minimizing the risk of damage to protected devices. This is crucial when protecting sensitive electronic components, where even a short-term exceeding of permissible current values can lead to failure. Thanks to this, it finds application in power supplies, control systems and other applications requiring precise protection.

Construction and product features

The D01 UQ fuse link has a compact "D" type (bottle type) construction, which facilitates its mounting in dedicated holders. Made of high-quality materials, it ensures reliable operation and long service life. The brown color of the housing makes it easier to identify the fuse link and its parameters. Size D01 indicates its physical dimensions and compatibility with appropriate fuse holders. The speed of action of this fuse link results from the special construction of the fuse element, which melts very quickly under the influence of excessive current, interrupting the circuit and protecting the connected devices.
