Int. E CORTE EM CARGA P/FUSIVEI S 4 x 800 A Protection against short-circuit and overload with the 3KL switch disconnector with fuses. 3KL switch disconnectors with fuses protect against overload and short-circuits as main control and EMERGENCY-STOP switches of switchboard assemblies, distribution boards, power supply and motor outgoing feeders. In conjunction with Siemens SITOR semiconductor fuses, they are also used in UPS systems, frequency converters and capacitor control systems. Key features of the Siemens 3KL switch disconnectors with fuses: 1. Close to prevent unauthorized operation. 2. Easier storage of accessory as can be used for other Siemens switch disconnectors such as the 3KA and 3KE. 3. Compliance with IEC 60947-1, IEC 60947-3 and VDE 0660 Part 107. 4. Modular design. 5. Quick and easy mounting.
