067204.5MXEP

Fuses are widely used in electrical circuits due to their ability to protect the circuits from power overloads, short circuits and ground faults. 067204.5MXEP is a fuse and relay unit having the same characteristics of standard fuses. It serves as an overload protection for medium voltage applications. Its application field includes power plants, wind farms, hydroelectric power generation, etc.

The 067204.5MXEP is designed in accordance with IEC 60947 standard. It is suitable for a variety of power systems ranging from 6 to 38 KV. It is equipped with a variety of features that provide protection against a wide range of overloads, short circuits and ground faults. It is capable of providing protection for both overloads and ground faults. It also includes a temperature sensor that ensures reliable operation in high temperature environments.

The overall working principle of the 067204.5MXEP is simple. The unit contains two fuses, one load and one over current fuse. The load and the over current fuses are connected in parallel, allowing the unit to provide both overload and short circuit protection. The load fuse is the one that provides primary protection against overloads and short circuits, while the over current fuse is used to provide back up protection. When the power overloads, the over current fuse will detect the overload and switch the control circuit, triggering the load fuse to break the current running through the circuit.

The 067204.5MXEP also includes a thermal protection built into the unit. The thermal protection prevents the unit from overheating due to extremely high current levels, by tripping the unit off when the temperature reaches a certain limit. This helps prevent damage to the electrical circuit due to overheating and potential fire hazards.

In summary, 067204.5MXEP is a fuse and relay unit that provide protection against power overloads, short circuits and ground faults for medium voltage applications. It is designed to meet the requirements of IEC 60947 standard. Its working principle is simple and it helps provide reliable protection against a range of electrical hazards.
