Key Specifications
- Manufactured in accordance with IEC 60282-1 and DIN 4362.
- Type-tested by KEMA, CESI, IPH and ICMET.
- High rupture capacity ensures reliable interruption of prospective short-circuit currents up to 63kA.
- Current-limiting action clears faults within milliseconds, protecting connected equipment from thermal, electrical, and mechanical stress.
- Low switching overvoltages during interruption protect connected equipment insulation from overvoltage damage.
- Low power dissipation minimizes heat generation during normal operation, preventing excessive temperature rise in the fuse and fuse holder, and extending service life.
- Electrolytic copper contact caps with silver or nickel plating for low, stable contact resistance over the product's service life.
- Equipped with spring-loaded striker pin for mechanical trip actuation and visual indication of blown fuse. Standard initial striker pin force is 80 N, with an optional high-force version available at 120 N.
- Thermal striker option available for enhanced overtemperature protection.
- Custom specifications available upon request.
