TR/3216FF2.5-R Application Field and Working Principle

Fuses are one of the earliest and most common electrical components. They play an important role as the "circuit breaker" in electricity safety systems and electrical supply systems.TR/3216FF2.5-R, as a type of fuse, is widely used in protecting circuits or equipment from damage due to overload or short circuit. It is designed for circuit breakers and plug-in type circuit breakers and is composed of 3 parts- fuse body, end caps and electrodes.

Application Field

TR/3216FF2.5-R fuses find its application mainly in various kinds of electrical circuits, and in all kinds of equipments, such as transformer, altemator, power cable, all kinds of electrical motor, electrical switch, electrical control, frequency inverter, high-voltage switch, breaker and surge protector, etc. It is mainly used for overcurrent and short circuit protection.

Working Principle

When the power is turned on, the fuse element conducts electricity from the power source, and the current passes through the fuse core, forming an electric arc in the fuse body. The current and temperature will raise instantly, and then the fuse element will be heated, softening, melting in a very short time. When the fuse element is completely melted, the chamber will be separated to cut off the current, thus it prevents further damage of the circuit or equipment.

Technical Parameters

The rated current of the fuse is 2.5A, and the cut-off current is 4.75A．The rated voltage is AC-500V/DC-250V, while the rated power dissipation of the fuse is 2.3W.

Installing Instruction

TR/3216FF2.5-R must be installed in the box or rail, and attention should be paid to the orientation of the fuse element. When installed correctly, the arrow on the body of the fuse points in the direction of the incoming current. The fuse-block must be fixed securely. When installed in a rail, make sure the fuse is fitted flush and remains firmly in place.

Conclusion

TR/3216FF2.5-R is one of the most common types of fuse. It is suitable for overcurrent and short circuit protection of various kinds of electrical circuits and equipments. With its superior technical parameters and firm structure, it is reliable and cost effective, making it a great choice for many applications.
