When power failures occur, our 3LD2 switch disconnectors safely disconnect and isolate electrical systems – and that applies to AC motors as well as air-conditioning systems and solar power installations. These switches have been proved in numerous applications, especially in the machine-building and conveyor system sectors and the chemical, food, and beverage industries. They’re certified as manually operated switch disconnectors in line with requirements specified by IEC 60947-3, DIN VDE 0660 Part 107, and EN 60947-3. According to DIN EN 60204-1, they can also be used as On/Off, EMERGENCY-STOP, and main control switches. Designs compliant with UL Standard 508 are available for international applications. In addition, variants certified to UL489 are available, which means that the switch can be used as the main switch for machines in the United States.
