Sentron load isolator switch 3LD, emergency stop switch, 3-pole, Iu: 16 A, operational power at AC-23 A at 400V: 7.5 kW, insulating material encapsulation for metric connection, rotary drive, red/yellow. The main and emergency stop switch 3LD serves as a repair switch for safe disconnection of loads in various environments. The applications of the 3LD network isolators 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 3LD has proven itself in many areas, particularly in processing and manufacturing machines in the machinery and conveyor construction, in the chemical industry, and in the food and beverage industry. 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 and globally applicable thanks to international IEC, UL, and marine approvals. 3. Protection class up to IP 65 with encapsulated housing for outdoor applications. 4. Usable for direct current applications. 5. Mounting types: front mounting, mounting plate, DIN rail. 6. Optimal network isolation from 16 A to 250 A through the lockable rotary drive.
