Cylindrical fuse link AM 4 A 10.3 x 38 HPC 013004

Professional motor protection in a compact form

The AM 4A HPC type cylindrical fuse link represents a proven solution in the field of short-circuit protection for electric motors. This 10×38 mm ceramic fuse has been specifically designed for industrial applications where reliable circuit separation is required under high inrush currents.

Electrical parameters and operating characteristics

The device operates with a rated current of 4A at a voltage of AC/DC up to 500V, making it a versatile solution for various types of electrical installations. The operating frequency of 42-62 Hz covers standard power grid ranges, and a power loss of 0.85W at the rated current ensures economical operation.

The utilization category aM (motor short-circuit protection) according to the IEC 60269 standard guarantees optimal time-current characteristics for circuits containing loads with high inrush currents. The ceramic body provides excellent thermal and mechanical resistance, and the absence of an indicator simplifies the design while maintaining full functionality.

Operating conditions and environmental parameters

The fuse maintains full functionality across a wide temperature range from -25°C to +40°C, allowing for installation in both heated rooms and unheated industrial halls. The storage temperature from -40°C to +70°C allows for long-term storage without degradation of parameters.

The IP20 protection rating protects against finger contact with live parts and against access by solid objects larger than 12.5mm in diameter. Installation is possible in vertical, horizontal, or tilted positions - this flexibility simplifies integration into existing installations.

Regulatory compliance and certification

The product meets the requirements of European standards EN/IEC 60269-1, confirming its compliance with European electrical safety standards. A breaking capacity reaching 100-120kA ensures effective separation even in the most unfavorable short-circuit conditions.

Compliance with LVD (2014/35/EU) and EMC (2014/30/EU) directives guarantees safety of use and electromagnetic compatibility in industrial environments. Each unit has a unique EAN code 3245060130046, enabling unambiguous product identification throughout the entire life cycle - from production through distribution to disposal after failure.
