Load disconnect switch 3LD3, Iu 40 A main switch, 3-pole, rated operational power at AC-23 A at 400V 18.5 kW, for panel installation, base switch with black rotary drive. The main and emergency stop switch 3LD ensures safe disconnection of loads in various environments. The applications of the 3LD3 network disconnect devices are diverse. After network disconnections, they ensure the safe isolation of the entire electrical equipment and can switch off, for example, three-phase motors as well as climate and ventilation systems. The 3LD3 is also ideally suited for use in control or switch cabinets, particularly for applications in small machines such as saws, compressors, pumps, concrete mixers, drilling machines, milling machines, and woodworking machines. The Siemens main and emergency stop switches 3LD are characterized primarily by: 1. Modular design, quick and easy assembly of auxiliary switches, N-PE terminal or 4th pole. 2. Versatile applicability thanks to local approvals. 3. One mechanical size for five electrical sizes. 4. Usability for DC applications. 5. Mounting types: front mounting, mounting plate, DIN rail. 6. Optimal network isolation from 16 A to 63 A through the lockable rotary drive.
