0287004.L Fuses Application Field and Working Principle

Fuses are important safety components in a range of electrical and electronic circuits and equipment. The 0287004.L, made by the renowned company Schurter, is a Low Breaking Capacity Fuse that can be applied in a range of applications due to its special characteristics.

Application Field

The 0287004.L is an ideal choice for installations, repairs and replacements, due to its low breaking capacity. Heat and overcurrent can be easily interrupted by the 0287004.L, which is particularly suitable for protecting low current circuits from tiny but potentially damaging short circuits. This is why the 0287004.L is ideal for use in low wattage bulbs, motors, battery chargers, home appliances and control boards.

When placed in series with an ignition coil, the 0287004.L prevents overvoltage from damaging the ignition coil. The 0287004.L can also be used in other high heat and low current applications, such as radiator cap systems and automotive fuel shut-off systems.

Working Principle

The 0287004.L consists of a metallic strip within a small ceramic tube that’s filled with a non-conductive compound. The strip conducts when the voltage falls below a set threshold and interrupts the current when the voltage rises above a set range. As current travels through the 0287004.L, heat builds up and causes the strip to expand. This reduces the cross section of the strip and limits the flow of current.

When the current reaches a predetermined point, the fuse strip melts and the current is broken, preventing damage to the circuit. The compound inside the tube has a low melting rate, so it takes longer to reach the predetermined melting point and thus offers more protection. This ensures that the 0287004.L will rapidly interrupt high current and offer additional safety.

Conclusion

The 0287004.L fuse is a reliable and versatile device that offers excellent heat resistance and proven protection against overcurrent and short circuits. The 0287004.L is ideal for low current, high heat applications and can be used in series with an ignition coil to protect it from overvoltage. Thanks to its low melting rate, the 0287004.L is a safe and dependable product.
