Load isolator switch 3LD3, Iu 25 A main switch 3-pole + N. Rated operational power at AC-23 A at 400 V 9.0 kW. Front mounting base switch with central hole mounting 22.5 mm. Black rotary drive 66 x 66 mm. The main and emergency stop switch 3LD ensures safe disconnection of loads in a variety of environments. The applications for the 3LD3 network isolators are diverse. After network disconnections, they ensure the safe isolation of the entire electrical equipment and can switch, for example, three-phase motors as well as air conditioning and ventilation systems. The 3LD3 is also ideally suited for use in control or distribution cabinets, particularly for applications in small machines such as saws, compressors, pumps, concrete mixers, drills, milling machines, and woodworking machines. 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 applicability thanks to local approvals. 3. A mechanical size for five electrical sizes. 4. Usable for direct current applications. 5. Mounting types: front mounting, mounting plate, DIN rail. 6. Optimal network isolation from 16 A to 63 A through lockable rotary drive.
