NALF type load switch-fuse combination electrical appliance (in accordance with IEC60420:1990 GB16926-1997)
NAL type load switch and NALF type load switch-fuse combination electrical appliances are load switches that combine compressed gas arc extinguishing and gas produced arc extinguishing introduced by ABB with more than 50 years of load switch design and production experience. So far, more than 600,000 units have been installed and used all over the world.
A combination electrical appliance composed of a load switch and a fuse combines the advantages of the load switch and the fuse. Any load current from the load switch to the rated breaking current is opened by the fuse and its striker. Any overcurrent up to the rated short-circuit breaking current of the combined appliance. The products are mainly used in: 1. As the circuit and transformer switch in the distribution network system. 2. Electric motor switch. 3. Capacitor switch.
Uses include: cable sectioner and transformer switch\motor switch (used with motor fuse CMF) \ switching capacitor bank\ as a component of assembling switch cabinets\ used in load switch cabinets\ compact substations and box transformers\ in public Application in business and industry.
