PTC resettable fuses are electronic components consisting of a ceramic body, PTC thermistors, and an insulating layer. They are widely used to provide protection from over current, over temperature, and short circuit conditions. The PTGL4SAS100K2N51B0 is a four-pole resettable fuse with a voltage rating of 16VDC and a current rating of 100A. It is UL, CSA and VDE approved.

The PTGL4SAS100K2N51B0 is designed for use in a range of applications such as industrial equipment, electronic appliances, lighting equipment, consumer electronics, and more. It is ideal for a variety of safety functions such as overload, overcharge, short circuit, and surge protection. This device offers a high breaking capacity, excellent temperature cycling capability, and fast circuit response times.

The working principle of a PTC resettable fuse is relatively simple. It comprises of two parts: an electrically resistive ceramic core and a small PTC (positive temperature coefficient) device. When current passes through the fuse, the PTC device heats up due to the resistance created by the ceramic body. This heat causes the PTC device to increase its resistance, thus limiting the amount of current that can pass through the fuse. In the event of an overload or short circuit, the PTC device begins to dissipate a lot of heat, causing the PTC device to reach its thermal threshold and effectively limiting the current. When the fault is corrected, the PTC device cools down and begins to decrease its resistance, allowing the current to flow again.

The PTGL4SAS100K2N51B0 is a highly reliable and durable device that is designed to last for millions of cycles. It has a built-in temperature cycling protection feature that helps prevent damage caused by overheating. It also offers a rapid circuit response time and a long service life. The PTGL4SAS100K2N51B0 is UL-certified and is compliant with a range of safety standards including the UL listing, CSA listing, VDE approval, and ESD/EMC standards.

Overall, the PTGL4SAS100K2N51B0 is a reliable and durable resettable fuse designed to provide circuit protection in a variety of applications. It is ideal for use in industrial equipment, electronic appliances, lighting equipment, consumer electronics, and more. The working principle of the device is relatively simple and involves the use of an electrically resistive ceramic body and a PTC device which increases its resistance when exposed to excessive current or heat. This helps to limit the amount of current that can pass through the fuse, preventing it from becoming damaged. The device is UL-approved and meets a range of safety standards.
