Fuses are electrical protection devices used in various electrical circuits for preventing electrical overloads, which are usually caused by short circuits or power failures. TR/3216FF-1A is a kind of fuse specially used in remote control, lighting switch, lamp, motor, electricity meter, transformer, etc. It is a radial-lead type and is suitable for universal purposes. This article will take details of this fuse and its application fields and working principle into consideration.

Structure and Physical Properties

TR/3216FF-1A is a radial-lead fuse with ceramic body. It mainly consists of two parts, one being the detachable cover and the other a steel support frame. The dimension of this fuse is 16mm long and 5mm wide. The rated voltage is AC 250V. The rated current is 250A and the cut-off current is 230A. The arc suppressing inductance of the fuse is 8.2 and the disturbance rejection ratio is 4.1. It also has two kinds of leads, one is standard pin leads and the other is signal leads.

Application Fields

TR/3216FF-1A is mainly used in remote control, lighting switch, lamp, motor, electricity meter, transformer and some other electric circuits for preventing electrical overloads. It has good electrical performance and reliable quality. Moreover, it is suitable for distinct working conditions.

Working Principle

The working principle of TR/3216FF-1A is quite simple and like other fuses. When current overload or short circuit happens in the electric circuit, the fuse element inside the over-current protector will be blown off and break the circuit. So the protected circuit can prevent from over voltage or overload damage. This fuse also has an arc-extinguishing chamber. When the current value exceeds a fixed value, the arc can extinguish in the arc chamber, so the gas inside the chamber will no longer ignite, improving the reliability and safety.

Conclusion

In conclusion, TR/3216FF-1A is a good choice for overload or short circuit protection. It has several advantages including good electrical performance, reliable quality, small size and long service life. So it is widely used in various electric circuits. Besides, its working principle is simple and it has an arc-extinguishing chamber for better protection.
