PTC resettable fuses, also known as polyfuse, are type of protection devices used to guard against electrical and mechanical overloading. While traditional fusible links offer protection against only overloads, PTC resettable fuses offer protection against both overloads and short circuits. As such, they are a great way to guard against electrical overloading and protect equipment from the damaging impact of power surges and voltage.

The 16VT170U is a PTC resettable fuse, specifically designed for automotive, marine, industrial, and consumer applications. It has an operating current rating of 10A and can work at a DC voltage rating of 16-170V. The 16VT170U features an automatic reset function, which allows it to automatically reset after a power outage or a large electrical current surge. Unlike traditional fuses which need to be replaced after they have been triggered, the 16VT170U is non-replaceable and will automatically reset to its original condition.

The working principle of the 16VT170U PTC resettable fuse is quite simple. It has a thermistor core, which is basically a resistor composed of three bands or elements of conductive material. When an excess of current flows through the device, the device will heat up due to the increased voltage. This increased temperature causes the resistive bands to expand, which in turn causes a temporary disconnection in the electrical current.

The device then cools down, and the thermistor core returns to its original shape. This will restore the connection, which will then enable the flow of current once again. This whole process happens almost instantaneously, thus ensuring fast protection against electrical overloads and short circuits.

The 16VT170U PTC resettable fuse is an excellent choice for protecting electrical appliances from overloads and short circuits. It is easy to install, offers reliable protection, and is much more cost effective than traditional fuses. Additionally, because it is resetable, the user does not need to constantly replace the fuse in order to gain protection. The 16VT170U is also suitable for numerous applications, such as automotive, marine, industrial, and consumer applications.
