RUSBF185-2

PTC resettable fuses are a well-known variety of fuse, and RUSBF185-2 is a popular example of this type of device. This fuses can be found in many different applications, from standard household appliance protection to high-tech consumer electronics. With the proliferation of consumer electronics in recent decades, these fuses have become an increasingly popular choice in circuits for protection against overcurrents or ground faults.

RUSBF185-2 fuses are available in a variety of package sizes, making them suitable for a wide range of applications. The most common sizes are 6.3x6, 5x20, 4x4, 3x6, 2x6, 1x7.5. The fuse consists of a metal casing containing a PTC (positive temperature coefficient) element, normally made of polymeric or ceramic. The metal casing acts as the terminal block, allowing the fuse to be connected in series or parallel with other components in the circuit. The PTC element, in turn, acts as a thermal fuse in the circuit. When the current passing through the circuit exceeds the rated current of the fuse, the PTC element will begin to heat up, causing an increase in its resistance. This in turn causes the total circuit current to be limited, reducing the risk of damage to the components.

RUSBF185-2 fuses are considered by many to be a very reliable and cost effective way of protecting components. They are especially useful for applications where it is necessary to protect sensitive components from overcurrents or ground faults. The fuses are also highly adjustable, allowing them to be set at different trip points, depending on the application. Additionally, the fuses can be reset manually after a fault has been cleared, making them very convenient. They also provide other advantages, such as reducing the risk of arcing and fire from overcurrents, and providing protection against overcharging of batteries.

In summary, RUSBF185-2 fuses are a popular type of PTC resettable fuses, suitable for a wide variety of applications. They are very reliable and cost effective, and offer a variety of advantages over other types of fuses, such as overcurrent protection and convenience. For these reasons, they are a great choice for circuits where protection of sensitive components is required.
