Fuse link 10.3 x 38 25 A GG 013325

Cylindrical gG fuse link for electrical installation protection

The Legrand gG type fuse link with dimensions 10,3×38 mm and a rated current of 25 A provides a reliable solution for protecting electrical installations against overload and short circuits. Manufactured as an ACR (Alta Capacità di Rottura) ceramic fuse, it ensures a high breaking capacity of 100 kA, making it suitable even for circuits with significant short-circuit currents.

Electrical parameters and operating characteristics

The device operates at a rated voltage of 500 V AC at a frequency of 50-60 Hz, meeting the requirements of the gG utilization category according to the IEC 60269 standard. This characteristic guarantees effective protection for both conductors and electrical devices against the effects of overload and short circuits.

The F (fast) tripping characteristic ensures an immediate response to exceeding permissible current values, minimizing the duration of the hazardous state in the circuit. Power loss at the rated current is only 2.7 W, which translates to low energy losses during normal operation.

Construction and operating conditions

The fuse with a diameter of 10,3 mm and a length of 38 mm has been designed for mounting in standard 10×38 type cylindrical fuse holders. The absence of an indicator simplifies the design and reduces production costs while maintaining full protective functionality.

The device maintains full efficiency across a wide range of operating temperatures from -25°C to +40°C, and during storage, it can be kept in temperatures from -40°C to +70°C. The ceramic housing provides excellent resistance to environmental conditions and stability of electrical parameters over time.

Normative compliance and certification

The fuse link has been approved by Bureau Veritas and meets the requirements of the European standard EN 60269-1 and the international IEC 60269. The product is covered by a 3-year manufacturer's warranty, confirming high manufacturing quality and reliability during long-term operation.

Compliance with European directives regarding electromagnetic compatibility and low voltage electrical equipment safety guarantees legality of use in all European Union countries.
