KTU-450

The KTU-450 is an electrical device specially designed to provide overload protection for electrical and electronic circuits. It is a special type of fuse used to prevent an overcurrent from damaging an appliance or various components within a circuit. The KTU-450 is a high speed, high current device, which is capable of fully interrupting short circuit currents up to the rate of their breaking capacity.

KTU-450s are used widely in a variety of commercial and industrial applications, such as motor controllers, transformers, switchgear, inverters, air conditioners, computers and other electronic devices. The device is often used as an alternative to circuit breakers for applications where a high level of current or frequent short circuit interruptions are expected.

The working principle of a KTU-450 is based on the basic property of electricity known as resistance. The device contains a coil of wire that comprises two copper strands with an aluminium core around it. When a certain amount of current flows through the wire, the coil will become heated, causing the aluminium core to expand and the device to be tripped. The device will then act to quickly interrupt any further current from passing through, thus preventing an overcurrent from damaging the appliance.

The KTU-450 also contains a tiny element known as a thermopile. This element is responsible for sensing any excessive temperatures in the device and quickly tripping it. This prevents any further heat build-up, thus protecting the appliance or components from thermal damage. The device also has a fast response time, meaning that it can protect against any potential electrical hazards quickly and reliably.

The KTU-450 is an important safety device that is used in a variety of electrical applications. It helps to protect equipment from overcurrents and short circuits, thus safeguarding people and ensuring that equipment operates optimally. The device also has a fast response time, meaning that it can quickly react to any hazardous electrical events. As such, the KTU-450 is an important device for electrical and electronic circuits.
