PTC Resettable Fuses, or polymeric positive temperature coefficient devices, are a type of electrical device designed to protect electrical circuits against overloads and short circuits without the need for replacement. The VTP200UXLLF is a high surge current breaking capacity, high reliability PTC Resettable Fuse designed specifically for overcurrent and overtemperature protection of many products in a variety of industrial and commercial applications.

The VTP200UXLLF is a fast-acting, temperature sensitive electric protection device. It consists of a resistive element, the PTC, which changes its resistance when the temperature of the device reaches its trip point temperature. When the current passes through the PTC, the temperature increases, and the resistance increases sharply to a level that limits the current. When the current decreases to the normal level, the device temperature gradually decreases and at a certain level, the resistance returns to the normal low level. This device has a wide range of application fields, including automotive, solar energy, electronic medical equipment, factory automation equipment, and industrial robotics.

The working principle of the VTP200UXLLF is relatively straightforward. The device is designed to be installed into a circuit as a form of over-current protection. When the current running through the device exceeds the device\'s rated limits, the internal resistance of the fuse will increase very rapidly due to the thermistor effect, thus limiting the current. This causes the temperature of the PTC device to increase, cutting off the current before it can cause any damage. After the current returns to normal levels, the device temperature will slowly decrease until the internal resistance returns to its original low levels.

The VTP200UXLLF’s primary applications include providing over-current protection in automotive, industrial and commercial applications. It is also well suited for use as a safety protection device in applications where lockout due to overheating needs to be avoided. In addition, the VTP200UXLLF is suitable for use in many areas, including solar energy, battery charging systems, home appliance applications, factory automation equipment, and even industrial robots.

The VTP200UXLLF is part of the family of PTC Resettable Fuses, which provides superior current protection and reliable operation without the need for replacement. It is allows for higher performance, better reliability, and greater flexibility than traditional fuses. With its wide range of application fields and working principle, it is an ideal solution for customers looking for a cost-effective and reliable over-current and overtemperature protection solution.
