The Protectron PBFT-LT-175A is a PTC (Positive Temperature Coefficient) resettable fuse, offering reliable circuit protection against overcurrent conditions. Supreme Components International is an authorised distributor of Protectron components, ensuring you receive genuine and high-quality products. This fuse features a 1.75A hold current, meaning it will carry up to 1.75A continuously without tripping. When an overcurrent event occurs, the fuse's resistance increases dramatically, limiting the current flow and protecting downstream components. Once the fault is cleared and power is removed, the fuse cools down and automatically resets to its low-resistance state, restoring normal circuit operation. This resettable functionality eliminates the need for manual fuse replacement, reducing downtime and maintenance costs. The PBFT-LT-175A is suitable for a wide range of applications, including consumer electronics, industrial equipment, and automotive systems. Its compact size and robust performance make it an excellent choice for enhancing circuit safety and reliability.
