NDG1-100+NCJ1

NDG1-100 is used for line facilities in buildings and similar locations, as well as in industrial power distribution systems, serving as an isolating circuit device. It can also be used for infrequent on-off operations. Two 3-pole NDG1-100 units combined with one NCJ1-3G1Z, or two 4-pole NDG1-100 units combined with one NCJ1-4G1Z, form a manual transfer switch for load transfer between two power sources in low-voltage circuits, while also ensuring safe circuit isolation.
