5MF 300

Fuses are an important form of circuit protection that limit the amount of current flowing through a circuit. The five MF 300 fuse series is a type of current-limiting fuses used to protect sensitive electronic equipment and other systems from electrical overcurrent events.The maximum current rating of the MF 300 series is 300 amperes and it is available in two body sizes.

MF 300 Application Field

The five MF 300 fuse series are primarily used to protect equipment from current overloads in industrial applications, power supplies, solar inverters, electric motor controllers, lighting fixtures, and other applications requiring high fault current interruption and current-limiting protection.It is especially well suited to protection of sensitive equipment in oil and gas, mining, and other hazardous environments.

Working Principle of MF 300

The five MF 300 fuse series use a unique time-delay design that limits the peak let-through current when subjected to an overload. This prevents damage to sensitive components. The fuses are designed to operate in an overload current condition without necessarily tripping immediately. The amount of time before the fuse trips depends on the severity of the overload and type of overcurrent. The series has a fixed time delay of 38 milliseconds and a fast operating time of 300 milliseconds.

The fuses are made from a high-temperature self-extinguishing ceramic core element with a silver alloy plated contact surface. The fuse also contains a wire wound element that enables the fuse to handle both AC and DC current. The fuses have an operating voltage of 300 volts.

Conclusion

The five MF 300 fuse series is a reliable and durable solution for protecting equipment from electrical overcurrent events. The fuse offers high-current and current-limiting protection for a variety of applications. The fuse is easy to install and provides a low cost solution for protecting sensitive components. The fused is designed to safely limit the amount of current flowing through a circuit and prevent damage from occurring.
