• Introduction

PTC Resettable Fuses, or polymeric positive temperature coefficient (PPTC), are widely used in many electronic applications. These fuses are designed to detect and prevent electrical faults through current and over-temperature protection. They are self-resettable and can be used again after they open or trip.

VTP210SLUF is one of these PTC resettable fuses specifically designed for protection in overcurrent and overtemperature situations, quickly and easily. Its application fields include automotive electronics, consumer appliances and industrial equipment. This fuse also meets the requirements of Underwriters Laboratories and Canadian Standards Association.

• Working Principle

VTP210SLUF is an active fuse that typically works on the principle of thermal runaway. This self-resetting fuse features high voltage (110VAC/600VAC), low current applications (2-210A). Its operation is based on the electrical conduction property of its semiconductor material, which is normally closed until the current passes through the device is too high, this will cause the device to rapidly heat up, increasing its resistance. As the resistance increases, the current limit is reached and the device quickly trips or opens.

The fuse consist of a polymeric material formulated to increase the trip current under overload conditions. At the same time, the polymeric material can rapidly reset or restore conduction at the initial nominal value. The fuse also features high surge capabilities and pulsating current-handling capability.

• Applications

VTP210SLUF is designed to be used in a variety of applications. The device is primarily used in automotive electronics, consumer appliances and industrial equipment. It can also be used in industrial applications that require protection from short-circuits and over-temperature conditions. It can be safely used for automotive, audiovisual, telecommunications, appliance and home electronics applications.

VTP210SLUF can also be used in low-voltage charger prototypes. Its working principle ensures that the charging current is never too high, thus protecting the internal electronics and the battery from overheating and short-circuiting. Its over-current protection feature guarantees against overloads and damage due to defective diode bridges or overcharging conditions.

The fuse can also be used in portable charging equipment, switching supplies, LED lighting and other battery-powered applications. The VTP210SLUF is designed to provide reliable protection while ensuring a long operating life, providing a safe working environment for the equipment and the user.

• Conclusion

VTP210SLUF is a type of PTC Resettable Fuse designed to detect and prevent electrical faults through current and over-temperature protection. Its application fields include automotive electronics, consumer appliances and industrial equipment and it can also be used in industrial applications that require protection from short-circuits and over-temperature conditions. Its self-reset feature allows it to quickly and easily restore conduction and protect against short-circuiting and overcharging. In conclusion, the VTP210SLUF provides a safe and reliable protection for a variety of applications.
