PTC resettable fuses, or polymeric positive temperature coefficient (PPTC) resettable fuses, are used when an electrical or electronic device needs to be able to reset itself after an overload or short. These fuses are also known as positive temperature coefficient (PTC) fuses, or simply resettable fuses. The primary function of these fuses is to protect electrical and electronic devices against short-circuits, overloads, and overtemperature conditions.

The 250R145TU PTC resettable fuse is designed for use in industrial applications such as HVAC systems, motor drives, lighting, solar energy, and consumer electronics. This fuse is designed with a fast trip time, a low current rating, and an operating temperature range of -40°C to +105°C. Additionally, it offers high surge current capability and superior surge withstand ability.

The working principle of the 250R145TU resettable fuse is based on the concept of positive temperature coefficient. It is made of a polymer material that changes resistance in response to temperature changes. When current passes through the fuse, the temperature increases, which causes the resistance of the fuse to also increase. This increases the voltage drop across the element, thus causing the fuse to open. When the current is removed, the fuse cools down, its resistance decreases, and the fuse is able to reset itself.

The 250R145TU PTC resettable fuse offers several advantages over traditional fuses. It is highly reliable, easy to install, and requires no maintenance. It ensures safe operation due to its high surge current capability and superior surge withstand ability. Additionally, it is relatively small in size, making it well suited for applications where space is limited.

The 250R145TU PTC resettable fuse is a reliable and efficient way to protect electrical and electronic devices from overloads, short-circuits, and overtemperature conditions. Its size and fast trip time make it an ideal solution for a wide range of industrial applications. With its superior surge capability and easy installation process, it is the perfect choice for protecting sensitive electronic components.
