PTC Resettable Fuses are a type of overcurrent protection devices which are used in electrical and electronic products for protection against short-circuit and overload conditions. The MF-RM005/240-2 PTC Resettable Fuse is a self-resetting, thermosensitive polymeric overcurrent fuse that provides reliable overcurrent protection. It is designed to open and reset itself when the current exceeds the rated limit, resetting automatically when the fault condition is removed.

The MF-RM005/240-2 is a radial leaded overcurrent fuse, with its output terminals being connection pads, and a variety of sizes and amp ratings available to suit the application. Its rated current is 240mA with a maximum opening current of 360mA, and a maximum operating temperature of 125°C. It has a high overload and short-circuit resistance capability, withstanding up to 10kA inrush current. It features fast response time, making it suitable for use in a wide variety of applications.

The MF-RM005/240-2 PTC Resettable Fuse has a wide range of applications in many different industries, including automotive, consumer electronic, medical, energy and lighting applications. It is mainly used in smaller devices, such as AC/DC wall adapters and power supplies, charging cables and other portable electronic products.

The working principle of the MF-RM005/240-2 is based on the thermally activated bi-metallic strip principle. The fuse has a bimetallic strip which is heated when an overcurrent passes through the fuse. When the current passes through the fuse, the bi-metallic strip is heated up and its temperature rises, causing it to expand or contract. This change in shape causes the fuse to open, interrupting the current. When the current is then removed, the bimetallic strip cools and returns to its original shape, allowing the fuselage to reset itself and restoring the connection.

The MF-RM005/240-2 is designed to provide reliable overcurrent protection and effective short-circuit protection. Its high overcurrent resistance capability and fast response time makes it a reliable and effective choice for use in applications that require the protection of circuits from surges or short-circuits. The resettable fuse is easy to install, and it is also cost effective and environmentally friendly.
