Ultra-fast fuse link D01 UQ GR 10A/400V 004311004

Safety of installations and semiconductor devices – fuse link D01 UQ gR 10A/400V

This fuse link, catalog number 004311004, is a reliable element protecting electrical circuits against the effects of overloads and short circuits. Designed to work with semiconductor devices, it provides quick and effective protection, minimizing the risk of damage. Its gR characteristic makes it ideal for applications requiring high selectivity and speed of action.

Characteristics and application

The D01 UQ gR 10A/400V fuse link is a component designed to protect circuits with a rated voltage of 400V AC and 250V DC. The rated current of 10A guarantees adequate protection for a wide range of applications. The gR characteristic (marked in red) ensures a quick response to short-circuit currents, which is crucial in the case of protecting semiconductor elements, which are particularly sensitive to sudden current surges. Thanks to this, the fuse link effectively protects sensitive components from damage and the electrical installation from more serious failures.

Construction and parameters

The fuse link is made in size D01, which ensures its compatibility with a wide range of fuse holders. Its construction based on a ceramic body guarantees high resistance to environmental conditions and stability of operating parameters. The short-circuit breaking capacity reaches 50kA at AC voltage and 8kA at DC voltage, which confirms its high effectiveness in emergency situations. The value of the total Joule integral of switching (65 A²s) testifies to its ability to absorb energy during short-circuit switching. Additionally, the fuse link is characterized by low power losses (4.2W), which translates into energy efficiency of the system.

It has a rated current of 10A, a rated voltage of AC 400V and DC 250V. Its characteristic is defined as gR, and the size is D01. The short-circuit breaking capacity is 50kA for AC and 8kA for DC, and the total Joule integral of switching is 65 A²s.

The weight of a single fuse link is only 6.6g, and the basic packaging contains 10 pieces (weight 71g). The transport packaging contains as many as 500 pieces (weight 35.62kg).
