CFP200A is a high-performance, low-fault-current fuse designed for protection equipment in electrical systems. It has two functions, the primary function is to protect the circuit from overcurrent and short circuit, the secondary function is the fault current limiter. The fuse has a high breaking capacity and a very low voltage drop, making it suitable for use in a wide range of applications.

CFP200A fuses are designed for use in low-voltage applications where high-fault-current protection is needed. It is most commonly used in heavy-duty industrial control circuits, motor control circuits, branch circuits, and other power electronic circuits. It can also be used in distribution networks to protect transformers. The fuses are also used in hand-held and portable devices that require protection from short circuits and over-currents.

CFP200A fuses are designed for easy installation and operation. They have a simple design, with a plug-in feature which makes them easy to install. The body of the fuse is constructed from UL94V-0 flame retardant material, and the internals are made from high-temperature materials. The fuse has an external trace for remote trip indication, which is used to monitor the status of the fuse.

The working principle of the CFP200A is based on the Joule- Thomson effect. When an overcurrent flows through the fuse, the current passing through the contact area generates heat. The increase in temperature causes a change in the resistance of the metal, resulting in a voltage drop across the fuse. This voltage drop is used to trip the fuse and safely disconnect the circuit.

CFP200A fuses are designed for a variety of applications, including circuit protection, over-current protection, short-circuit protection, and thermal protection. They can be used in motor control circuits, heavy-duty industrial control circuits, branch circuits, and other power electronic circuits. The fuse effectively limits the fault current, prevents serious damages due to short circuits and over-currents, and ensures safe operation of the equipment.
