Fuse link 5 x 20 3.15 A 010230

Ceramic fuse cartridge for electrical installation protection

The miniature cylindrical cartridge 5×20 mm with a rated current of 3.15 A and a voltage of 250 V AC provides reliable protection against overload and short circuits in domestic and industrial installations. Manufactured as a type F (fast) ceramic fuse, it ensures an immediate response to exceeding the permissible current.

Operating parameters and technical characteristics

The device operates within a frequency range of 50-60 Hz with a power loss of 2.2 W at the rated current. It is characterized by a fast tripping characteristic (F), allowing for instantaneous circuit interruption in the event of a short circuit or significant overload. The operating temperature range is from -25°C to +40°C, and storage is possible within the range of from -40°C to +70°C. The cartridge does not feature an optical indicator of operation.

Applications and compatibility

The fuse finds wide application in protecting high-sensitivity electrical equipment, including light dimmers, emergency lighting units, transformers, and power distribution boards. It is compatible with fuse holders and bases designed for 5×20 mm miniature cylindrical cartridges. The product meets the requirements of the IEC 60269 standard in the "other" utilization category.

Construction and operating conditions

The ceramic housing provides high thermal and mechanical resistance, guaranteeing stable operation in difficult environmental conditions. The dimensions of the cartridge are exactly 5 mm in width and 20 mm in length, enabling installation in standard fuse holders. The IP20 protection rating protects against finger contact and access to hazardous parts.
