FWA-600A is a high voltage air gap fuse, which contains expensive "rare earth metals". It is the most reliable and cost effective fuse available in the market to protect systems and circuit components from high voltage arcing and current surges. FWA-600A is a reliable and cost effective alternative to other fused arc systems.FWA-600A is primarily used for the protection of low and medium voltage distribution systems, electrical equipment, and control circuits. Its main purpose is to limit line fault currents and damage to components or equipment in the circuit. The FWA-600A provides superior levels of current limiting performance and so, it is well suited for applications that require short-circuit protection and fault current limitation. It also has the capability to interrupt larger currents, thereby making it an ideal solution for low and medium voltage circuit breakers, switchgear, and power transformers.The working principle of a FWA-600A is relatively simple. When the current exceeds preset values, the arc gap will become insufficient to support sustained arc currents resulting in a rapid increase in pressure which causes the fuse to blow. This rapid increase in pressure produces an explosive effect that fractures the fuse element and produces a rapid extinguishing of the arcing.The FWA-600A fuse is designed to operate under high voltage conditions of up to 600 volts AC. It has a low resistance to current flow,low internal losses, and small physical size during normal operation which make it suitable for many specialized applications. Upon reaching its maximum current rating, the FWA-600A will open and de-energize the circuit, and remain substantially in the same physical condition. The fuse is also highly stable and does not require any maintenance.The FWA-600A can provide reliable protection against overloads, short circuits, and circuit damaging current surges. Its fast ballistic action at low short circuit currents is capable of preventing expensive equipment damage and downtime. The current limiting capability of the FWA-600A also helps to reduce equipment losses due to arc flash by limiting the energy dissipated during arcing and reducing the risk of personnel injury.Due to its low cost, compact size, and superior performance levels, the FWA-600A is a popular choice for many specialized applications. The fuse is widely used in data processing applications, instrumentation, automotive applications, and various control systems.The FWA-600A is an excellent choice for providing reliable overcurrent protection in low and medium voltage distribution systems. With its superior current limiting performance and fast arcing rate, it is the ideal solution for protecting sensitive circuits and equipment from current surges and line faults.
