NHRT41 fuse switch disconnector is applied in the circuit of rated current frequency of 50Hz, rated current from 160A to 630A and rated voltage of AC500V / AC800V (250A~630A) and below. NHRT41 Series fuse-switch disconnectors can be widely applied in industrial and commercial building and solar combiner boxes. They are infrequently manually operated multipolar fuse combination switches. Switch on and off load and provide safe isolation and protection against overcurrent.
