The RL3005-10-110-12-PTO resettable fuse is a type of Polyfuse device known as a PTC (positive temperature coefficient) Resettable Fuse. It is designed to protect electronic circuits from overcurrent and overvoltage conditions. PTC fuses are typically used in applications that involve sensitive or expensive components, since they are able to protect the components from thermal, electrical and mechanical damage. The device works by detecting an overload and tripping its internal fuse, which cuts power to the circuit.

The RL3005-10-110-12-PTO is specifically designed for AC line voltage applications that require both over-current and thermal protection. This resettable fuse is constructed using a metal oxide formulation which can detect short circuit current up to 150 amps, and can handle surges up to 500 amps. The device has a fast response time of less than 0.5 seconds, making it ideal for protecting circuits from damaging surges.

The working principle of the RL3005-10-110-12-PTO is quite simple. When an overload is detected, a built-in thermal fuse melts, disconnecting the circuit and creating an open circuit. As the temperature of the device increases, the resistance of the fuse decreases, allowing the current to be re-established and restoring the circuit’s continuity. This process can be repeated again and again, as long as the reset button is pressed.

Being a PTC Resettable Fuse, the RL3005-10-110-12-PTO also has some additional safety features that make it more suitable for AC line applications. Firstly, it has a built-in disconnect feature, which completely separates the device from the circuit if the device is exposed to an overvoltage surge. Secondly, the device will self-disconnect if the current is too high for the device to handle. Thirdly, the device has a built-in temperature sensor which will disconnect the device if the temperature exceeds its rating.

The RL3005-10-110-12-PTO is an efficient and reliable way of protecting circuits from over-current and over-voltage conditions. Its fast response time and safety features make it an ideal solution for AC line voltage applications. The device is relatively inexpensive and simple to install, and can provide superior protection for your most valuable components.
