Description
SENTRON, Switch disconnector 3LD, emergency switching-off switch, 3- pole, Iu: 25 A, operating power / at AC-23 A 400 V: 9.5 kW, front-mounted, rotary operating mechanism, Red / yellow, central mounting 22.5 mm of the handle The 3LD main and emergency switching-off switch as a maintenance switch for safe disconnection of loads in a wide variety of environments. There are numerous possible applications for the 3LD 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. 3LD have proven themselves in many fields, particularly in processing machines in mechanical and conveyor system engineering, and in the chemical sector and food and beverage industries. 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 and global applications possible thanks to international IEC, UL and marine approvals. 3. Degree of protection IP65 with encapsulated housing for outdoor applications. 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 250 A with lockable rotary operating mechanism. www.siemens.com/switching-devices. Siemens offers a comprehensive portfolio of protection, switching, measuring and monitoring devices, distribution systems as well as switches and sockets for safe and efficient electrical infrastructure in buildings and industry.
