Fuse link 5 x 20 0.5 A 010205

Miniature ceramic fuse for electrical installation protection

The 5 x 20 mm fuse link with a rated current of 0.5 A is a compact solution for protecting electrical circuits from the effects of overloads and short circuits. The product features an H tripping characteristic, which ensures rapid response to rated current exceedances.

Construction and technical parameters

The ceramic fuse with dimensions of 5 x 20 mm (width x depth) is designed for operation in AC voltage circuits. Power loss at the rated current is only 0.3 W, which minimizes energy losses during normal operation. The device operates at a standard frequency of 50-60 Hz, typical for most electrical installations.

The ceramic construction provides high thermal resistance and stability of parameters during operation. The absence of an indicator simplifies the design and lowers production costs while maintaining full protective functionality.

Application and compatibility

The miniature fuse link finds wide application in industrial automation, electronic devices, and domestic installations. The H characteristic makes it ideally suited for protecting circuits supplying devices with variable loads.

The 5 x 20 mm size is an industry standard that allows for mounting in typical fuse holders and modular distribution boards. The 0.5 A rated current protects delicate electronics from damage while allowing the protected devices to operate correctly.

Operating conditions and safety

The device maintains full functionality within a wide range of operating temperatures from -25°C to +40°C, enabling installation in both heated and unheated rooms. The storage temperature ranges from -40°C to +70°C, guaranteeing parameter stability during transport and long-term storage.

The product meets the requirements of the IEC 60269 standard regarding miniature cylindrical fuses, ensuring predictable behavior during overload or short circuit. The ceramic construction eliminates the risk of arc material splashing when the fuse link blows.
