PTC Resettable Fuses have many applications in industrial, commercial, automotive and medical settings. This devices offer an economical and convenient alternative to traditional fuses for their ability to automatically reset after an overcurrent event. The PTCCL05H131FTE is a popular PTC Resettable Fuse due to its high current rating of 131 amperes, low trip temperature of 75 °C, and easy one-step installation. In this article we will discuss the applications and working principle of the PTCCL05H131FTE.

The PTCCL05H131FTE is most commonly used in automotive, industrial and commercial applications. It is also suitable for use in medical equipment, as it has a low temperature trip threshold, making it suitable for protecting sensitive monitoring and safety equipment. In the automotive sector, it is commonly used in the protection of the ECU, EPS, motor control and ABS systems.

The working principle of the PTCCL05H131FTE is fairly simple. It consists of a resistor element with a bi-metallic element, connected to a contact terminal. When the temperature rises above its set trip temperature, the doughnut-shaped bi-metallic element expands, crushing the resistor element, which reduces its resistance. This, in turn, causes a large current surge through the contact terminal, which trips the fuse, disconnecting the circuit and preventing any further increase in temperature. Once the temperature has cooled down, the bi-metallic element relaxes, and the resistor element returns to its original size and resistance, thereby resetting the fuse.

The PTCCL05H131FTE is designed to offer a cost-effective and reliable solution to overcurrent protection in automotive and industrial applications. Thanks to its low trip temperature and high current rating, it is suitable for use in applications where traditional fuses may not be able to offer sufficient protection. It is also extremely easy to install, eliminating any need for complicated wiring or specialized tools.

The PTCCL05H131FTE is a popular and cost-effective PTC Resettable Fuse, thanks to its high current rating, low trip temperature, and ease of installation. It is most commonly used in automotive, industrial and commercial applications, as well as in medical equipment. Its working principle is based on the expansion and contraction of a bi-metallic element, which reduces the resistance of the resistor element, and trips the fuse when the temperature rises above the set trip temperature.
