Sentron load disconnect switch 3LD, emergency stop switch, 3-pole, Iu: 100 A, operational power at AC-23 A at 400 V: 37 kW, insulating material encapsulation for metric screw connection, rotary drive, red/yellow. 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 guarantee the safe isolation of the entire electrical equipment and switch off, for example, three-phase motors as well as air conditioning 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 the following features: 1. Modular design, quick and easy installation of auxiliary switches, N-PE terminal, or 4th pole. 2. Versatile use thanks to local approvals. 3. One mechanical size for five electrical sizes. 4. Usable 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.
