vertical fuse switch disconnector While performing isolation and protection functions in electrical systems, switching equipment must also meet short-circuit withstand requirements to cope with fault current surges in the circuit. nhrt40 vertical fuse switch disconnector The short-circuit continuous current (Icw) and short-circuit surge capability (Icm) should be clearly specified for engineering design and selection reference. According to international standards, switching equipment must withstand a certain short-circuit current value for a predetermined time without being damaged.
