Introduction

0BLF020.T is an electrical specialty fuse, designed according to IEC 60127-3, that is used in a wide variety of applications. It is composed of an electronic element, a current-limiting fuse, and a time rising-current devices. It can provide protection against current overloads and can withstand high surge currents with a minimal risk of false tripping.

Application Fields

This fuse is mainly used for high current and short-circuit protection in all kinds of circuits including AC, DC, mixed AC/DC, AC half-wave rectified or unrectified, and AC/DC rectified or unrectified. It can be applied in radio-cassette equipments, motor starters, programmable logic controllers, inverter drives, motor drives, solar inverters, capacitors and lighting equipment, as well as other applications that require very high surge and interrupting capacity.

Working Principle

The 0BLF020.T fuse operates according to a current-limiting principle. When the current passes through it, the fused element melts and the current-limiting device starts to open. As a result, the current is limited and the fuse can safely absorb the excess current flow without damaging the protected system. The time-rising current device ensures that a fuse which has been disconnected due to an overload reaches a fully open state before its restoration is completed. This ensures that the electronic element will be in a protected state during the restoration period.

Features and Benefits

The 0BLF020.T fuse has a number of features and benefits that make it a useful and reliable tool for protecting circuits. It has a high interrupting capacity and a low current-voltage drop, so it can provide effective protection with minimal risk of false tripping. The fuse has a compact and lightweight design, so it can be easily installed, used, and maintained. In addition, the fuse is designed to withstand large current surges and can safely dissipate large amounts of energy.

Conclusion

The 0BLF020.T fuse is an electrical specialty fuse that is used for high current and short-circuit protection in a wide range of applications. It operates according to a current-limiting principle, meaning that it can limit high overload currents while still providing effective protection. The fuse has a compact and lightweight design, as well as a high interrupting capacity and low current-voltage drop, making it a reliable and effective tool for protecting circuits.
