Sentron load break switch 3LD, main switch, 3-pole, Iu: 100 A, operational power at AC-23 A at 400V: 37 kW, insulation material encapsulation for metric screw connection, rotary drive, black. The main and emergency stop switch 3LD ensures safe disconnection of loads in a variety of environments. The applications of the 3LD3 network disconnection 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 are also ideally suited for use in control or distribution 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 mounting of auxiliary switches, N-PE terminal, or 4th pole. 2. Versatile applicability thanks to local approvals. 3. A mechanical size for five electrical sizes. 4. Usability for direct current applications. 5. Mounting types: front mounting, mounting plate, DIN rail. 6. Optimal network disconnection from 16 A to 63 A through the lockable rotary drive.
