Cylindrical fuse link AM 1 A 10.3 x 38 HPC 013001

Cylindrical fuse link for motor protection

The AM 1 A cylindrical fuse link with dimensions 10,3 x 38 mm is a professional electrical protection component designed primarily for the protection of electric motor circuits. The product belongs to the aM (motor short-circuit protection) category according to the IEC 60269 standard, making it an ideal solution for industrial and automation applications.

Construction and technical parameters

The fuse is manufactured as an ACR ceramic link (Alta Capacità di Rottura - high breaking capacity), which guarantees effective electric arc quenching during the interruption of short-circuit currents. The compact design with a diameter of 10,3 mm and a length of 38 mm allows for installation in standard fuse holders of this type.

The device operates at a rated voltage of 500 Vac and a rated current of 1 A, while simultaneously providing a very high breaking capacity of 100 kA. This parameter guarantees the safe interruption of even very large short-circuit currents, protecting the installation from damage.

Application and compatibility

The aM type fuse link has been specifically designed for the protection of electric motors, where it is necessary to distinguish between inrush current and short-circuit current. Unlike gG type fuses, aM links allow the free flow of motor inrush currents for a specified time, while simultaneously interrupting the circuit immediately in the event of a short circuit.

The product is compatible with supply frequencies in the range of 42-62 Hz, allowing for use in both European systems (50 Hz) and other regions. Thanks to the universal nature of the AC/DC voltage, the link performs well in various industrial applications.

Operating conditions and environment

The fuse maintains full functionality at an operating temperature from -25°C to +40°C, enabling use in both cooled rooms and high-temperature environments. For long-term storage, the product withstands temperatures from -40°C to +70°C.

Power loss at the rated current is only 0,45 W, which minimizes the additional thermal load on the installation. The device does not have an external trip indicator (without striker), which is typical for industrial applications where status is monitored through resistance measurement or other diagnostic methods.

Compliance and standards

The fuse link meets the requirements of the European standard EN 60269-1, confirming its compliance with the highest electrical safety standards. The product is part of the LEGRAND offering - a global leader in electrical installation solutions, which guarantees the highest quality of workmanship and reliability of operation.

Thanks to IMQ certification and compliance with the CB IEC scheme, the device can be used in all applications requiring the highest standards of electrical installation safety.
