Electrical, Specialty Fuses

KTK-3/4 is a series of miniature fuses providing reliable protection against dangerous electrical overloads and short circuits. They are designed for use everywhere that a secure system and convenient resetting are required including both adjustable circuits (where the fuse can be adjusted to the current needed) and non adjustable circuits. They are a great choice for applications where quick access for maintenance or replacement is crucial.

Application Field

KTK-3/4 fuses are designed for applications where a secure, reliable protection against overloads and short circuits is required. These fuses are appropriate for data communication systems, industrial electrical equipment, temperature control systems, and instrumentation and security systems. Additionally, KTK-3/4 fuses are suitable for adjustable or non adjustable, single or three-phase circuits.

Working Principle

KTK-3/4 fuses are designed to cut off the power supply in the case of an electrical overload or short circuit. In the event of an overload or short circuit, the internal element of a KTK-3/4 fuse quickly melts and interrupts the power supply. This element is made of a special silver alloy which has a relatively low melting point. This allows the fuse to react quickly to an overload or short circuit.

The main difference between a KTK-3/4 fuse and a standard fuse is the presence of a replaceable element. When the fuse is used, the main element melts, but it can be easily replaced by a new one. This makes the KTK-3/4 fuse very resistant to overloads and short circuits, and ensures that it can be used for a long time. The replaceable element also makes the KTK-3/4 fuse very easy to reset without needing to replace the entire fuse unit.

Another feature of KTK-3/4 fuses is that they are capable of withstanding extremely high currents which can occur in the event of a severe overload or short circuit. This is due to the presence of a specially designed element which is able to conduct very high currents. This allows the KTK-3/4 fuse to provide reliable protection in the event of a severe overload or short circuit while still being easy to reset.

Overall, KTK-3/4 fuses provide a safe and reliable way of protecting electrical equipment from dangerous overloads and short circuits. They are designed to be easy to reset, and their replaceable elements allow them to be used for a long time. The presence of a specially designed element also enables them to withstand very high currents without breaking.
