355MT

Fuses are an essential component in protecting electrical circuits and equipment from ove r current and short circuit conditions. The the 355MT series Fuse, manufactured by Littelfuse, is a special grade of fuse designed for use in applications where the current load and demand cycles are constantly varying. The 355MT fuse has a current rating of 3300A and functions within the current range of 500A to 3200A.

Application Field

The 355MT Fuse is designed for applications in power system projects in the following industries: mining, oil exploration, and petrochemical, metallurgical, electrical engineering and other power system projects requiring high rated current and high intermittent current.

Characteristics and Working Principle

The 355MT fuse is unique because of its superior performance in a wide range of current ratings. The fuse has an ability to withstand sudden or extreme electrical overloads, short-term surges, as well as current cycling, more efficiently than other types of fuses.In operation, the 355MT Fuse uses an ultra-rapid melting fuse element design, which melts quickly when subjected to current overloaded conditions. The simultaneous melting of both ends of the fuse element and an equally quick repolarization of the arc removes it from the circuit. As a result, the total melt time of the fuse is greatly reduced, thereby providing an override protection system that is safe and reliable in the power system. The unique characteristic of the 355MT fuse also offers superior protection during normal operations, as the arc voltage is lower and the current is less, enabling the circuit breaker to be able to handle the current safely and reliably.

Conclusion

In conclusion, the 355MT series Fuse manufactured by Littelfuse is a special grade of fuse designed to protect electrical circuits and equipment from overloads. The fuse has a current rating of 3300A with the ability to withstand sudden or extreme electrical overloads, short-term surges, as well as current cycling, more efficiently than other types of fuses. This ultra-rapid melting element design also reduces the total melt time of the fuse, providing an override protection system that is safe and reliable in the power system.
