Sentron load isolator switch 3LD, emergency stop switch, 3-pole, Iu=250A, operational power at AC-23 A at 400V: 132 kW, floor mounting with door coupling, rotary drive, red/yellow, 4-hole mounting of the handle. 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 three-phase motors as well as climate and ventilation systems. 3LD switches have proven themselves in many areas, particularly in processing and manufacturing machines in machine and conveyor construction, in the chemical industry, and in the food and beverage industry. The Siemens main and emergency stop switches 3LD are characterized by: 1. Modular design, quick and easy installation 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 options: front mounting, mounting plate, DIN rail. 6. Optimal network isolation from 16 A to 250 A through lockable rotary drive.
