Description
Switch disconnector with fuse 630 A, Size 5, 3-pole for LV HRC fuse Sz. 2 and 3 Front operating mechanism center Basic unit without handle flat terminal 3KF switch disconnector with fuses as main, EMERGENCY STOP or maintenance switch. Depending on their size, 3KF switch disconnectors with fuses enable a rated current between 32 and 800 A to be switched on and off. Furthermore, they fulfill a safety isolation function in all age circuits. 3KF switch disconnectors with fuses are optimized for complex applications in which LV HRC fuses are used. 1. Switch disconnectors with door coupling or direct operating mechanism in five sizes can be used in a variety of applications. 2. Simple retrofitting of functions possible thanks to an extensive range of accessories. 3. Reliable protection against electrical accidents by means of locking functions, touch protection and automatically interlocked fuse cover in the switched-on state. 4. Rugged technology with high short-circuit strength for high system availability. 5. Quick installation on the standard mounting rail with frame sizes up to 80 A. 6. Efficient engineering with extensive CAx data. 7. Reliable protection also for wind power plants up to 690 V + 10%. www.siemens.com/switching-devices.
