The PBFT-LT-100A is a PTC (Positive Temperature Coefficient) resettable fuse from Protectron. Supreme Components International is an authorised distributor of Protectron components, ensuring you receive genuine and high-quality products. This resettable fuse is designed to provide reliable circuit protection against overcurrent faults. When an overcurrent event occurs, the PTC fuse heats up and increases its resistance, limiting the current flow and protecting the circuit. Once the fault is cleared and the power is removed, the PTC fuse cools down and returns to its low-resistance state, automatically resetting the circuit. With a trip current of 100A, the PBFT-LT-100A is suitable for a wide range of applications requiring robust circuit protection. PTC resettable fuses offer a significant advantage over traditional fuses by eliminating the need for replacement after a fault, reducing downtime and maintenance costs.
