Fuse link 8.5 x 31.5 20 A 012320

Ceramic fuse link for electrical installation protection

The cylindrical fuse link with dimensions 8,5×31,5 mm is a reliable component for protecting low-voltage circuits against the effects of overloads and short circuits. Made of ceramic, it ensures long-term protection of electrical installations in residential buildings and industrial facilities.

Operating parameters and technical characteristics

The device operates at an alternating voltage of AC 400V with a rated current of 20A, making it suitable for protecting typical power supply circuits. The ceramic material withstands high temperatures and maintains parameter stability during operation.

The gG type tripping characteristic provides full protection—against both overloads and short circuits—which is crucial for installation safety. A breaking capacity of 20 kA allows for the safe interruption of even very high short-circuit currents.

Power loss at the rated current is only 1,7W, which minimizes energy losses during normal operation. The product maintains full functionality across a wide range of operating temperatures from -25°C to +40°C, and during storage, it withstands extreme conditions from -40°C to +70°C.

Application and compatibility

The component finds wide application as a protective element in building distribution boards, control cabinets, and automation panels. It is particularly recommended for protecting power supply circuits for lighting, sockets, and auxiliary devices.

Compatibility with standard fuse bases for 8×32 mm cylindrical links facilitates installation in existing systems. The product is designed for use with copper conductors with a cross-section of 2,5 mm², which corresponds to typical domestic circuits according to NF C 15-100 standards.

The absence of a blown fuse indicator simplifies the design—information about the link's status is obtained through circuit continuity measurement or preventive replacement according to a maintenance schedule.

Standards and operating conditions

The product meets the requirements of the IEC 60269 standard for domestic fuse links, confirming its safety of use and compatibility with European electrical installation standards. The EAN code 3245060123208 enables easy product identification in warehouse systems.

Color coding (green color) facilitates quick identification of parameters during installation and service work. The operating frequency is adapted to the standard power grid of 50/60 Hz, allowing the product to be used in most European countries without additional modifications.
