Fuses

0251005.PF009L Application Field and Working Principle

Fuses are an essential and important component in all electronic systems, playing an important role in safety and circuit protection . The 0251005.PF009L is a type of glass-bodied fuse and comes in a subminiature size of 2.5x10mm. Its advantageous size allows it to be used in a variety of circuit protection solutions, and this particular model is a general purpose slow blow fuse for use in low and medium voltage applications.Slow blow fuses are designed to handle momentary high inrush current, adjusting its internal temperature accordingly. This happens due to its very special and unique construction. The fuse is filled with quartz sand and has a bimetallic strip at its centre. A bimetallic strip is composed of two different metals (such as iron and copper) that expand at different temperatures. This strip is placed around the important component where it is heated up by current passing through it. When the heat from the current passing through the fuse reaches a specific temperature, the bimetallic strip will bend, breaking the circuit in a fraction of a second.The 0251005.PF009L\'s specific application fields include residential and commercial systems, motor control, audio equipment, and instrumentation. Its nominal voltage rating ranges from 250 V AC to 400 V AC and its breaking capacity is >2A/1000V. This fuse is also UL, CSA and ENEC approved for worldwide usage and carries a variety of certificate numbers.Due to its miniature size, the 0251005.PF009L is suitable for use in shallow-depth controls boxes and other limited space applications. Its body is made of glass, preventing any interference from the surrounding electrical environment and its printed leg are made of nickel-plated copper, providing it with a long-term life span. The 0251005.PF009L can be integrated into the circuit design in series and parallel network.The 0251005.PF009L is the perfect component for any application requiring circuit protection from overloads and short circuits, as its design allows it to be used in a wide variety of applications and its small size makes it the ideal solution for confined spaces.
