TR1/6125TD5-R Datasheet/PDFTR1/6125TD5-R, a medium-voltage fuse with high interrupting capacity, is widely used in the power system protection for safety. It works in a wide temperature range and can protect a large area of power system against short circuit and overload.
The working principle of a TR1/6125TD5-R fuse is based on the melting of a metal alloy or a semiconductor element when an excessive current passes through it. When an over-current occurs in the power system, the internal heat of the fuse will be increased. This heat is then transferred to the metal alloy or the semiconductor, which eventually melts to break the circuit, cutting off the power circuit. In this way, the power system can be protected from overload.
TR1/6125TD5-R fuses are mainly used in medium-voltage power systems and mainly used in industrial automation, transformer protection, motor drive, high-power electrical equipment and other fields. In the power system, TR1/6125TD5-R fuse can effectively protect power system from damage of short circuit and overload. In order to provide better protection, TR1/6125TD5-R fuses can be used in combination with other protective devices such as circuit breakers, current limiters, etc.
TR1/6125TD5-R fuses consist of two parts: a metal alloy or a semiconductor element and a housing. The metal alloy or semiconductor element is responsible for heat transfer and providing the current-limiting capability. The housing is used to maintain an air gap between the alloy/semiconductor element and the surrounding environment, thereby preventing any arc or spark from occurring.
The TR1/6125TD5-R fuse has a number of advantages, such as high breaking capacity, high temperature stability, low operating voltage, prompt working characteristics, and quick breaking time. It is capable of working in extreme temperatures and can protect a large area of power system against short circuit and overload. It can also be combined with other protection devices for more cost-efficient, reliable, and safer protection.
In conclusion, TR1/6125TD5-R fuses are widely used in the protection of medium-voltage power systems. It works by melting a metal alloy or semiconductor element when excessive current passes through it. This effectively cuts off the power circuit and protects it from damage of short circuit and overload.
