0477012.MXEP

Fuses provide necessary protection for electrical circuits by breaking the circuit if there is an overload in current. 0477012.MXEP fuses are specially designed for motor circuits and offer a number of benefits over standard fuses.

Application Field

0477012.MXEP fuses are designed for the specific application of protecting 3-phase motor circuits. They are suitable for applications up to 35kV and employ very sensitive components that will provide protection in the event of a motor overcurrent. They are commonly used in large industrial motor controllers, high voltage power supplies, and generator controllers.

Working Principle

0477012.MXEP fuses employ a three-phase design that is capable of measuring current levels in each of the individual phases of the circuit. This helps ensure accurate protection of the circuit as it is able to detect any imbalance in the current levels. In the event of an overcurrent, the fuse will open and the circuit will be broken.

The fuses also employ a thermal element that is sensitive to heat rises due to overcurrent situations. The fuse will open the circuit before the electrical components become damaged due to excessive current overheating the components. This helps prevent costly repairs due to damage caused by excessive current.

In addition, the fuses incorporate a special feature called Diverse Time Delay that helps protect against overloads that are caused by sudden impacts or peak currents. This feature allows the fuse to remain closed during brief surges in current, but will trip and open the circuit if excessive current is sustained for an extended period of time. This helps protect the circuit from damage due to prolonged overloads.

Advantages

0477012.MXEP fuses offer a number of advantages over standard fuses including increased accuracy of protection, improved protection against overloads, and greater reliability. The three-phase design helps ensure accurate measurement of current levels and the Diverse Time Delay feature helps protect against sudden surges in current.

Additionally, the use of a thermal element helps protect against overheating of components due to excessive current. The added protection against overloads increases the overall reliability of the system, helps reduce repair costs, and extends the life of the components.

Conclusion

0477012.MXEP fuses are specifically designed for protecting motor circuits with three-phase designs and provide superior protection against overloads. The fuses employ a three-phase design that is capable of measuring current levels in each individual phase and a thermal element to protect against overheating of components due to excessive current. Additionally, the Diverse Time Delay feature helps protect against sudden surges in current. The improved protection offered by these fuses result in increased reliability and extends the overall life of the components.
