PTC resettable fuses are a type of fuse used to provide electric current protection and short-circuit protection in a variety of circuits. 06R155BU is a member of this fuse family, with its application field and working principle being particularly unique and important. Below we will discuss in detail what the application field and working principle of a 06R155BU resettable fuse is.

The application field of a 06R155BU resettable fuse is quite wide and general, including low voltage dc circuits, portable electronics, telecommunications, and more. In all these applications, it’s primary purpose is to protect devices from an overload or short circuit. The 06R155BU resettable fuse features a polyfuse with a wide range of characteristics that make it perfect for these applications. First, it’s rated for a maximum operating voltage of 600V DC, providing an effective way to protect a single circuit. Second, when overloaded the fuse will be reset by itself, thus resetting the system it is protecting.

The working principle of a 06R155BU resettable fuse is quite simple, yet effective. It works by using a negative temperature coefficient, or NTC, of polymeric material inside the body of the fuse. When the applied voltage exceeds the parameter of the fuse, the material will heat up, causing it to open and disconnect the circuit. When the voltage is reduced, the material will then cool down, resetting the fuse and allowing the current to flow again. This process enables the fuse to be self-resetting with minimal disruption to the circuit, and is one of the many reasons why the 06R155BU is so widely used.

In addition to its self-resetting capability, the fuse also features a low thermal threshold of 6-30 Amps, meaning that it is capable of being used in a variety of circuits without the need for circuit breakers. The fuse also features a high surge/spike rating of 1000V, offering superior protection against power surges and spikes. Finally, the 06R155BU resettable fuse is RoHS compliant and is UL recognized, offering peace of mind when using it in a variety of applications.

The 06R155BU resettable fuse is one of the most widely used types of polyfuses, offering a variety of features and benefits. It’s wide application field and simple working principle make it perfect for low voltage applications, providing an effective way to protect circuits from overloads and short circuits. As with all polyfuses, it should be used in accordance with its rated parameters and be tested regularly for proper operation. By doing so, the 06R155BU can be trusted to keep your circuits safe and protected.
