PTC resettable fuses are a type of fused circuit protection units that are designed to prevent overcurrent and short circuit conditions from damaging sensitive electronic components or other types of equipment. They work by automatically interrupting the circuit as soon as an overcurrent or short circuit condition is detected. PTC resettable fuses are a great way to provide protection for all types of electrical and electronic circuits, from the most basic consumer electronics to sophisticated industrial machinery.

The PFMU.010.2 is a cord-mounted PTC resettable fuse designed for use in industrial and commercial applications. It features a 19 mm ID barrel shape with a rated current of 10 A and a rated voltage of 250 V. The fuse is rated for up to 50,000 overload cycles and is UL Recognized and CSA approved. It is also designed for use in a variety of environmental conditions, including temperatures ranging from -40°C to 85°C. The fuse is RoHS compliant and weighs only 0.55 g.

PTC resettable fuse technology works by using special thermistors called polymeric positive temperature coefficient (PPTC) devices or polymeric thermal fuses. These devices contain electrically resistive elements called varistors that can act as a fuse until the overload current rises above a certain threshold. When it does, the varistor will divert the excess current away from the protected circuit, providing circuit protection.

Once the excess current is gone, the PPTC device will reset and the circuit will resume functioning as normal. This makes PTC resettable fuses ideal for applications where frequent excessive current conditions exist, or where the circuit load has the potential to vary dramatically over time. These fuses are also much more reliable than traditional fuses, since they don\'t require manual resetting or replacement, and can be used in a variety of environmental conditions.

These fuses are also often used in applications where power must be provided on a temporary basis, such as with remote start or emergency lighting systems, as well as for motor control applications. In these cases, the PTC resettable fuse ensures that a reliable, uninterrupted power source is provided for the duration of the operation. They are also commonly found in power supplies for many consumer electronics products.

The PFMU.010.2 PTC resettable fuse is designed for reliable, flexible, and safe operation in a variety of indoor and outdoor applications. It is small enough to be easily incorporated into most circuits, and can provide reliable protection and performance for years to come. Whether you\'re looking to protect sensitive equipment or provide a safe source of unreliable power, PTC resettable fuses are a great option.
