Fuses

Fuses are electrical safety devices which work by automatically cutting off the power when an over current is detected. The 3402.0047.11 is a type of fuse which is a direct current (DC) fuse rated at 250Volts and 12 Amperes.

Application Field

The 3402.0047.11 can be used in a variety of different applications. At 12 Amperes, the fuse is perfect for protecting consumer-grade electrical devices such as refrigerators, washing machines, televisions, radios, and other similar products. It can also be used to protect motors with currents up to 12 Amperes. Additionally, the fuse is suitable for protecting delicate components from overloaded power, so it can also function as a “fail-safe” device in the case of an unexpected power surge.

Working Principle

The 3402.0047.11 uses a metal strip of low melting temperature. This strip is connected in series between the power source and the load. When the current passes through the strip, the increasing temperature causes it to melt and break the circuit, disconnecting the power source and the load. This prevents the current from flowing, and effectively limits the amount of current that is allowed to pass through the circuit.

The main disadvantage of the 3402.0047.11 is that it fails to operate at temperatures below 0°C, so it may not be suitable for use in arctic climates. Additionally, the low current it is rated for makes it less effective at higher currents, so it is not suitable for use in more powerful circuit applications.

Conclusion

The 3402.0047.11 is a Direct Current (DC) fuse rated at 250Volts and 12 Amperes, and is perfect for protecting consumer-grade electrical devices and motors up to 12Amperes. It works by using a metal strip of low melting temperature which evaporates when the current passes through, thereby breaking the circuit and preventing the current from flowing. However, it may not be suitable for use in arctic climates or more powerful circuit applications.
