Updated：July 17,2026 17:59PM
The NDG1-100 Series disconnector is suitable for AC 50Hz/60Hz circuits with rated voltage up to 415V and rated current up to 100A. It is used for isolating circuits in building and similar facilities as well as industrial distribution systems. It can also be used for infrequent switching 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. It is used for load transfer between two power supplies in low-voltage circuits while ensuring safe electrical isolation.
