PTC Resettable Fuses are a type of fuse that provides electronically controlled over-current and over-temperature protection. A typical resettable fuse is composed of a polymer PTC (positive temperature coefficient) resistor and a circuit protector element. Such fuses are designed to detect current or temperature overloads and to react by tripping or automatically resetting, depending on their current rating. PTC Resettable Fuses are commonly used in consumer, industrial and automotive applications.

The PFMF.160.2 is a type of PTC Resettable Fuse, designed for high current protection in a wide range of applications. This device is rated for up to 160A of continuous protection with an interrupting capacity of 1250A, making it suitable for use in circuit protection in industrial and automotive applications. The PFMF.160.2 is designed to automatically reset after a fault has occurred and provide superior protection against thermal and electrical overloads. Furthermore, the PFMF.160.2 has an integrated “residual current” monitor, which monitors the current of the protected circuit even after the fault has been cleared.

The working principle of the PFMF.160.2 is fairly simple. When the circuit current reaches a set overload limit, the PTC Resettable Fuse’s resistor element heats up, causing a “trip” that opens the circuit. Once the current has dropped to a safe level, the resistor element cools down and the fuse resets, allowing the circuit to be closed again. Additionally, the PFMF.160.2 is designed to be especially resistant to thermal shock, making it a reliable and robust protection device.

In summary, the PFMF.160.2 is a type of PTC Resettable Fuse, designed for high-current protection and rated for up to 160A of continuous protection. The working principle of this device is fairly simple and it is designed to be highly resistant to thermal shock. The PFMF.160.2 is commonly used in consumer, industrial and automotive applications for circuit protection applications.
