Detail

Load disconnector 3LD3, Iu 40 A Main switch 3-pole Rated operating capacity at AC-23 A at 400 V 18.5 kW floor mounting Basic switch with door coupling Central hole mounting 22.5mm Rotary actuator red / yellow 66 x 66 mm with auxiliary switch 1OE + 1S The 3LD main and emergency off switch for safe disconnection of loads in a wide variety of environments. There are numerous possible applications for the 3LD3 disconnector units. After disconnects from the grid, they ensure safe activation of all of the electrical equipment, thus switch, for example, to three-phase motors, but also air-conditioning and ventilation systems. 3LD3 are also ideal for control panels, in particular for applications in small machines (for example saws, compressors, pumps, concrete mixers, drills, mills, and woodworking machinery) Key features of the Siemens 3LD main and emergency off switches: 1. Modular design, fast and easy mounting of auxiliary switches, N-PE terminal, or 4-pole 2. Versatile thanks to local approvals. 3. One mechanical size for five electrical sizes. 4. Can be used for DC applications. 5. Types of mounting: Front mounting, mounting plate, standard mounting rail. 6. Optimized disconnect from 16 A to 63 A with lockable rotary operating mechanism.
