PTC Resettable Fuses protect electrical wiring from overload and short circuits. The MF-LS300 is a low resistance and high thermal tolerance 12/24 Volt PTC Fuse, which allows for greater current flow than ordinary fuses. With its lower internal resistance than ceramic PTC’s and greater thermal tolerance, the MF-LS300 is the ideal choice for protecting automotive, agricultural, industrial, and recreational vehicle electrical systems.

The MF-LS300 has an operating range of 0-48V and a peak current of 300A, making it suitable for protecting both short-circuit and overload situations. The fuse is self-resetting, meaning that it will reset itself at a preset temperature, and can be used in a wide range of applications. Its low internal resistance also means that the MF-LS300 has less of an impact on system efficiency.

The MF-LS300 is designed to be used in DC applications in both low and high temperature environments. It is ideal for protecting vehicle electrical systems, since its resistance is much lower than conventional ceramic PTC’s, so it will not impede system performance. The fuse also has a high temperature tolerance and can withstand up to 200°C, allowing it to be used in extreme environment.

The working principle of the MF-LS300 is based on a Metal-Fiber Thermistor. The thermistor is made up of a wire core surrounded by a metal-fiber body, which is coated with a heat-conductive material. When electric current passes through the fuse, the temperature of the thermistor increases, which causes it to expand. Once it reaches a preset temperature, the thermistor contracts back to its normal size, which trips the fuse and breaks the circuit. After cooling off for a certain amount of time, the thermistor will reset itself and the circuit can be re-energized.

The MF-LS300 is an ideal choice for protecting automotive, agricultural, industrial, and recreational vehicle electrical systems, due to its low internal resistance and high temperature tolerance. It has a wide enough operating range that it can be used in a variety of applications and the self-resetting feature of the fuse ensures that it will be able to protect against both short-circuit and overload situations. The working principle of the MF-LS300 is based on a Metal-Fiber Thermistor, which is able to expand and contract at a preset temperature, tripping the fuse and breaking the circuit. Its self-resetting feature and wide operating range make the MF-LS300 an ideal choice for protecting electrical wiring from overload and short circuits.
