Feature

– Low minimum breaking current, low power losses and low arc-voltage;

– High breaking capacity and effective short-circuit prospective current limitation;

– Fuses are the fastest overload protection devices for high short-circuit currents;

– The fuse with the indicator has a safe indication, can show the fusing when the indicator pop-up;

– Superior insulating material, large creepage distance and suitable for different environments;

– The terminal of fusant contacting with the end-plate (or connecting plate) use the technology of spot welding;

– The fusant is made of pure copper strip, the fusion tube is made of high strength china. The extinguishing medium is made of pure quartz sand;

– Compliance to IEC60282-2 standard for full voltage ratings.
