JJN-300

The JJN-300 is a specialty fuse designed for electrical applications in a variety of industries. This type of fuse is used to protect electronic circuits from potentially damaging effects due to short circuits or overloads. It is a resettable type fuse which means it can be reset after a fault, without having to be replaced, making it more cost effective over a period of time. It is available in a wide range of amperage ratings from 1 to 30 amps, and can accept a variety of international voltage standards.

Application field

The JJN-300 is most commonly used in motor control circuits, industrial process control, power supply systems, telecommunications networks, computer systems, and other specialty applications where overcurrent protection is needed. It is also used in consumer electronics such as TVs and DVD players. It can be found in a variety of products such as circuit boards, lighting fixtures, power tools, and more.

Working Principle

The JJN-300 works by using a mechanical actuator to sense an overload or short circuit condition. When the current in the circuit exceeds the fuse’s rating, the actuator opens the fuse, interrupting the flow of current. After the fault condition has been removed, the fuse can be reset by pushing the reset button. The reset button has to be pressed until the actuator has fully reclosed. This ensures that the fuse is connected and ready for use again.

Advantage

The JJN-300 is a very reliable, cost-effective option for overcurrent protection. Its resettable design eliminates the need to replace the fuse, which saves time, money, and reduces waste. In addition, the fuse is UL certified, making it safe to use in many different applications.

Conclusion

The JJN-300 is a versatile, reliable, resettable fuse that offers a cost-effective solution for overcurrent protection. It is suitable for a variety of applications and is UL certified for safety. It is an ideal choice for those looking for a reliable, cost-effective alternative to replacing fuses.
