Sentron load disconnect switch 3LD in enclosure, maintenance and repair switch with EMC shielding plate, 3-pole, Iu: 16A, AC23A 400V at 50/60Hz: 7.5kW. In frequency converter operation: AC20 400V at 0-550Hz: 4kW, 1S + 1Ö 20-150ms leading, insulation material encapsulation for metric screw connection, rotary drive, black, lockable in 0 and I positions, including shielding clamps. 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 disconnecting devices are diverse. After network disconnections, they ensure the safe isolation of the entire electrical equipment, switching off, for example, three-phase motors as well as air conditioning and ventilation systems. 3LD have proven themselves in many areas, particularly in processing and manufacturing machines in the machinery and conveyor construction, in the chemical industry, or in the food and beverage industry. The Siemens main and emergency stop switches 3LD are characterized primarily 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 shipbuilding approvals. 3. Protection class up to IP 65 with encapsulated housing for outdoor applications. 4. Usable for DC applications. 5. Mounting types: front mounting, mounting plate, DIN rail. 6. Optimal network disconnection from 16 A to 250 A through the lockability of the rotary drive.
