They account for factors such as voltage, inductance, capacitance, line resistance, and fault distance. The fuses withstand temperature shocks, shifting and braking load currents, mechanical vibrations, and offer high breaking capacity, low I²t, low temperature rise, low power consumption, and long service life.
The fuse features a tubular design with a variable cross-section pure silver conductor, sealed in a high-temperature-resistant, high-strength ceramic tube. It is filled with high-silicon quartz sand as the arc-extinguishing medium.
