SENTRON Load Break Switch 3LD, Emergency Stop Switch, 3-pole, Iu: 160 A, Operating power at AC-23 A at 400V: 75 kW, front-mounted, 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 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 heating, ventilation, and air conditioning 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, as well as in the food and beverage industry. 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. Versatility and global applicability thanks to international IEC, UL, and marine approvals. 3. Protection class up to IP 65 with encapsulated housing for outdoor applications. 4. Suitability for DC applications. 5. Mounting types: front mounting, mounting plate, DIN rail. 6. Optimal network disconnection from 16 A to 250 A through lockable rotary drive.
