PTC Resettable Fuses, otherwise known as polyfuses, are designed to automatically protect equipment against hazardous electrical conditions such as short-circuits, over-current, and over-temperature. The PFR.185 is a type of resettable fuse specifically designed for use in high-frequency, automotive, and industrial applications. The unique features of this fuse make it an ideal choice for these types of applications, as it is able to reset itself after the fuse has tripped.

The PTC Resettable Fuse is a two-ply resin construction with a twisted-pair of conductors. The conductors are connected together with the help of a thermal stress relief insert, which helps to reduce the effects of mechanical and thermal stresses on the twisted-pair of conductors. The thermal stress relief insert also reduces the likelihood of damage to the resistor element, which is the main component of the fuse. In order to maximize its effectiveness, the PFR.185 is designed with added flexibility to make sure that it is able to provide maximum protection to the circuit.

The working principle of the PFR.185 is very simple. When the current in the circuit exceeds the rated current, the thermal stress relief insert begins to heat up. This causes the resistor element to become saturated, which causes the resistor to become open. The open resistor breaks the circuit and the current is diverted, which stops the current from flowing through the equipment and prevents it from being damaged.

The PFR.185 is designed to be reset after the fuse has tripped. The reset process begins with the removal of the thermal stress relief insert. Once the insert is removed, the resistor element is allowed to cool and the resistor returns to a closed condition. This allows the current to flow normally again and the equipment is protected from further damage.

The PFR.185 is designed to provide the best possible protection in a variety of applications. It is perfect for high-frequency, automotive, and industrial applications. It is also able to provide reliable and effective protection in more general electronic applications. These fuses have a wide range of options to choose from, making them the ideal choice for protecting various electricals.

The PFR.185 is the perfect choice for those in need of reliable and effective protection from hazardous electrical conditions. It is designed with a unique thermal stress relief insert that helps to reduce the risk of damage and to reset itself after a fuse has tripped. This allows the current to be diverted and prevents further damage to the equipment. By using a PFR.185, users can rest assured that their equipment is protected from short-circuits, over-current, and over-temperature conditions.
