Fuse link 5 x 20 10 A 010296

Ceramic safety for electrical installations

The 5x20 mm cartridge fuse with a rated current of 10A is a compact protective solution in a ceramic housing, designed for installation in electrical distribution boards. The Legrand brand product ensures reliable circuit protection against overload and short circuits in domestic and industrial installations.

Operating parameters and technical characteristics

The device operates at an alternating voltage of 250V AC and a frequency of 50-60 Hz, making it compatible with typical power grids. The H type tripping characteristic (slower than F) provides adequate overload protection while allowing for short-term current surges characteristic of starting electric motors.

A power loss of 4.6W at the rated current guarantees efficient operation without excessive heat generation. Compact dimensions (5x20 mm) allow for dense packing in distribution boards, and the ceramic construction ensures high resistance to environmental conditions.

Operating conditions and environmental resistance

The fuse maintains full functionality within a wide range of operating temperatures from -25°C to +40°C, enabling use in both heated and unheated rooms. For long-term storage, the product is designed for a temperature range from -40°C to +70°C, maintaining its parameters even after prolonged storage.

The design meets the requirements of the IEC 60269 standard, confirming its compliance with international electrical safety standards. The ceramic housing provides natural insulation as well as resistance to moisture and temperature changes.

Application and system compatibility

The product is intended for installation in standard 5x20 mm fuse holders, commonly used in residential and industrial distribution boards. Due to the lack of an optical trip indicator, circuit continuity testing is required during installation diagnostics.

The fuse performs particularly well in circuits powering household appliances, LED lighting, and small electric motors. The 10A rated current protects typical socket and lighting circuits from overloads that cause conductor overheating.
