What is the KTU-750?

The KTU-750 is an electrical circuit-protection device, also known as a specialty fuse. It is specifically designed for applications that require superior protection from short circuit, overload, and over-voltage events. The KTU-750 is rated for operation between 750 and 4000 amps, making it suitable for a range of applications that require protection from high currents.

Application Fields

The KTU-750 specialty fuse is suitable for a variety of applications in the industrial, commercial, and residential sectors. It is commonly used to provide short circuit and overload protection in motor control circuits, AC power distribution systems, and HVAC systems. In the residential sector, it protects circuits from faults caused by faulty wiring or lightning strikes. It is also suitable for use as an over-voltage protection device for lighting systems.

Working Principle of KTU-750

The KTU-750 specialty fuse is a current-limiting device that is designed to protect against short-circuit and over-current conditions. When a breaker trips due to an overload or short circuit, the fuse element will melt and separate, breaking the circuit and preventing further damage. The amount of current allowed to flow through the fuse is designed to be within safe limits for the connected equipment. This type of fuse is designed to work efficiently and quickly, protecting connected equipment from damage due to surges and overloads.The KTU-750 specialty fuse is constructed from two parts: a circuit connecting unit and a fuse element. The circuit connecting unit consists of two contact blocks, one connected to the hot busbar and the other connected to the neutral wire. The fuse element is a metal wire that is heated, and it melts when current reaches the melting point of the metal. The melt can open the circuit, breaking the circuit and preventing further damage.The KTU-750 specialty fuse is designed to provide superior protection from malfunctions due to high currents. It is rated for operation between 750 and 4000 amps and is suitable for a range of applications. The fuse is constructed from two parts, a circuit connecting unit and a fuse element, and is designed to quickly open the circuit when too much current is flowing through the circuit.
