PTC Resettable Fuses, commonly referred to as PPTCs or polymer positive temperature coefficient fuses, are devices that are installed in conjunction with electronic circuitry to protect against surge currents or over-currents. PTC resettable fuses are usually made from a method involving "self-limiting current paths" so that the current flow upon start-up, or sudden surge currents, is limited to a safe level. Of course, power is never interrupted in case of a fault occurring or during system start-up. They act as a sort of automatic circuit breaker fuse, making them the ideal choice for protecting power supplies and equipment.

The PFSM.150.33.2 resettable fuse is a particularly common polymer positive temperature coefficient (PPTC) fuse. It is a one-time use device that requires replacement once the intended current capacity has been exceeded. That being said, when this resettable fuse material is subjected to an overcurrent situation, the material properties of the device will heat up, causing a "trip" point to be activated. This trip point will redirect the current away from the protected device, preventing it from being damaged, while also allowing the user to simply "reset" the fuse and continue to use the device. As such, it is a safer and more reliable option than traditional glass fuses.

The PFSM.150.33.2 resettable fuse has many applications in modern electronic devices such as computers, cameras, consumer electronic devices, home appliances, security systems, and alarm systems. It has a variety of features tailored to specific applications, such as varying current ratings from 3A to 15A, a large temperature range of -40°C to +85°C, a sealable design, UL recognition, and it can be used both indoor and outdoor.

The working principle behind the PFSM.150.33.2 resettable fuse is fairly simple. The device is designed to act as a current limiter when it is subjected to a sustained over-current situation. The material properties of the device will heat up, creating a trip-point in the device which redirects the current away from the protected device, and at the same time resets the fuse back to its original state, allowing it to be used again. The advantage of the PPTC devices is in their ability to reset themselves without being replaced, whereas traditional glass fuses need to be replaced after being triggered.

The PFSM.150.33.2 resettable fuse stands out from the others due to its durability, its UL rating, and the fact that it allows for multiple cycles of resettability. It is an ideal solution for protecting a variety of sensitive equipment and devices from over-currents and short circuits. The device also meets the most demanding design requirements and can be easily integrated into modern applications.
