PTC Resettable Fuses are electronic components designed to protect circuits against over-currents and unstable voltages. They have the capability to be reset after a fault is cleared, thus saving time and money, and eliminating the need to replace blown or damaged fuses. The PFRA.700 is a PTC Resettable Fuse that is specifically designed for powering up motors and heavy inductive loads.

The PFRA.700 is designed to protect circuits from over-currents and is designed for use with DC applications between 4 and 48 volts. It has a current rating of 7 amperes, and a maximum energy rating of 30 joules. The fuse is constructed of a polymeric material that is heat and flame resistant, and the fuse is housed in a rugged plastic housing. It has an integrated red LED indicator that is lit when the fuse is activated and blinks when the fuse is reset. The PFRA.700 also features an automatic reset function which allows the fuse to reset itself without the need for manual resetting.

The PFRA.700 can be used in a wide variety of applications, including the powering of motors, heavy inductive loads, and critical systems in industrial, automotive, and consumer electronics. The fuse is robust and reliable, and is capable of handling large current surges with ease. The fuse has been tested to meet strict international safety standards and is UL Recognized.

The working principle of the PFRA.700 is fairly simple. When a current surge or voltage spike occurs, the PTC material in the fuse melts and opens the circuit, interrupting the flow of current to the load. Since the fuse is self-resetting, once the fault has been cleared and the power restored, the PTC material will cool, allowing the current to flow through the fuse again. The PFRA.700 also features an LED indicator which will indicate when the fuse has been activated, and after it has been reset.

In conclusion, the PFRA.700 is a reliable and highly efficient PTC Resettable Fuse designed to protect circuits from over-currents and unstable voltages. It is designed for use with DC applications between 4 and 48 volts, and is capable of handling a maximum current rating of 7 amperes. The fuse features an integrated LED indicator and an automatic reset function, making it suitable for use in a variety of applications.
