PTC Resettable Fuses are designed for single-phase and three-phase applications. They could protect low voltage circuits from overload or short-circuit conditions, while allowing current to maintain normal operation levels. The RUEF090-2 Resettable Fuse is the most popular type of PTC Resettable Fuse and is widely used in domestic and industrial applications. The RUEF090-2 fuse offers good protection, resetability and low power consumption.

The RUEF090-2 fuse is a polymeric positive temperature coefficient (PPTC) device. It consists of a metal substrate embedded in a thermosetting plastic case. During normal operation, the conductive paths of the PPTC fuse remain in a low resistance state. If there is an unintended high current caused by an overload or short circuit, the temperature of the plastic will rise, and will become resistive to reduce the current through the circuit. This temperature dependent resistance characteristic of the PPTC device is the main working principle of the RUEF090-2 fuse.

The RUEF090-2 fuse has a number of beneficial characteristics, such as excellent protection against overload and short circuit currents, making it the ans ideal choice for protecting electronic circuits. It operates with no time-lag and and can be reset to the low resistance state manually. In addition, its low power consumption means that it does not create heat during normal operation, resulting in efficient power use and a potentially longer lifespan for the circuit.

The RUEF090-2 fuse is a cost-effective protective solution for low voltage applications, with its small size and low weight making it suitable for use in a variety of applications. It exhibits reliable performance and is relatively easy to install and reset. It also features high temperature stability and environmental insulation as well as good surge protection.

The RUEF090-2 Resettable Fuse is a great choice for protecting low voltage circuits, as it can provide reliable protection against overload and short circuit currents and reset quickly and efficiently. With its excellent characteristics and low power consumption, the RUEF090-2 Resettable Fuse is a beneficial and cost-effective protective solution for a wide range of single-phase and three-phase applications.
