PTC Resettable Fuses

PTC Resettable Fuses are a new generation of fuses that are designed to protect electronic circuits from overload and short circuit damage. These fuses reset themselves after the circuit has been disconnected from the main power supply. This unique feature makes them ideal for use in applications where it is not practical or cost-effective to replace traditional fuses.

PTR030V0800-BK Application Field

The PTR030V0800-BK PTC Resettable Fuse is ideal for applications in the Aerospace, Automotive, Defence, Industrial, Medical and Telecommunications industries. This PTC Resettable Fuse is suitable for use as a component in primary protection applications, as it provides rapid tripping when an overload or short-circuit occurs. This type of fuse is also used as a protection device in a variety of secondary protection applications such as solar inverters, hybrid/electric vehicles, LED/CFL lamps, and UPS systems.

PTR030V0800-BK Working Principle

The PTR030V0800-BK PTC Resettable Fuse is a polymer-based fuse which contains a series of fusible elements that are connected in series. When the load current reaches the nominal fuse current rating, heat is generated due to the resistance of the fusible elements which causes the fuse to trip. This trip function is reversible, as the fusing element cools down, and the fuse will reset itself when the thermal energy is released. The PTR030V0800-BK PTC Resettable Fuse is designed to provide protection against secondary and primary over-currents. Its high hold current rating ensures that the fuse remains tripped even when excess current is applied for short periods of time. The recycling time of this fuse is fast, which ensures that the device can be put back into service quickly after it has tripped. The PTR030V0800-BK PTC Resettable Fuse is designed to protect circuits from short circuit or overload damage. It has a low power consumption and its construction ensures minimum power loss. This fuse also offers reverse polarity and transient protection which helps to keep the circuit safe in the event of reverse supply or power surge. In conclusion, the PTR030V0800-BK PTC Resettable Fuse is a reliable, cost-effective device that protects electronic circuits from overvoltage, short-circuit, or overload damage. Its self-resetting capability makes it ideal for applications where it is unsafe or impractical to use traditional fuses and its fast trip and reset times make it ideal for high-drain systems.
