PTC resettable fuses are a special type of device composed of a thermistor and a resistor. They provide a two-way protection for the equipment they are connected to, meaning they protect both the equipment and the user from the effects of an external overload. The term PTC stands for “positive temperature coefficient”, referring to the fact that the resistance of the thermistor increases as the temperature rises. The PTGL07AR650H8B52A0 is an example of a PTC resettable fuse, designed to protect equipment from short-circuits, overcontrolling, and sudden power surges.

The PTGL07AR650H8B52A0 is typically used for applications such as motor auto start/stop circuits, white goods, lighting systems, small household appliances, and other equipment that require protection against short-circuits, overoccupancy, and sudden power surges. These fuses are also suitable for high-risk applications, such as medical equipment and cashpoints.

The PTGL07AR650H8B52A0 operates on the principle of using a thermistor as the switch element. When an overload current is detected, the thermistor will generate heat and its resistance will increase. This increase in resistance will result in a decrease in the current flowing through the fuse, thereby protecting the equipment from damage. Once the current is below the threshold level, the thermistor’s resistance will drop and the fuse will reset itself, allowing the current to flow again. This process allows the fuse to reset itself without having to be manually reset, thereby ensuring continuous protection.

In addition to providing protection against short-circuits, overcurrent, and sudden power surges, the PTGL07AR650H8B52A0 also features a built-in protector diode which further protects the equipment against voltage spikes. Furthermore, the device is also designed to be flame-retardant, meaning that it will not cause a fire in the event of an overload.

The PTGL07AR650H8B52A0 is a reliable and cost-effective solution for protecting equipment from the effects of an external overload. It is designed to be easy to use and requires minimal maintenance. Furthermore, it serves as an effective secondary protection in case of primary fuse failure, providing peace of mind to the user. The PTGL07AR650H8B52A0 is well suited for use in a variety of applications, making it an ideal choice for protecting electronic devices against short-circuits, overcurrent, and sudden power surges.
