PTC Resettable Fuses (PTCRs) are designed for a variety of industrial and commercial applications, and the PFMF.110.2 is one of the most popular. The product is used for a range of applications, from protecting audio systems to providing short-circuit protection for motors.

The PFMF.110.2 has a unique design that makes it well suited for the various applications. It should be noted that the fuse is rated for 600 volts AC or DC, and can handle a wide range of currents. Its current rating can range from 10 to 50 amps, and its thermal time weighting curve ensures excellent circuit protection.

The PFMF.110.2’s working principle relies on the PTCR thermoplastic material it is made from. PTCR stands for PolymorphTronic Circuit Resistor, and it is a type of thermoplastic material which consists of a blend of panphilated thermoplastics. This material is designed to offer excellent high-temperature performance, excellent low-temperature performance, and a high degree of current-limiting capability.

When an over-current situation arises, the PFMF.110.2 activates its current-limiting mechanism in just a few milliseconds. The PTCR material has a high melting point, and in response to the high current, it melts and creates an open circuit. This causes the current flow to be cut off, protecting the circuit.

The PFMF.110.2 is able to protect against both over-current and transient voltage spikes. Its low internal impedance ensures that current is effectively diverted away from the circuit, protecting it against any potential damage.

When the current-limiting mechanism is triggered, the PFMF.110.2 resets itself in 8-20 seconds. The PTCR material re-solidifies, enabling the current to flow again. This self-resetting feature makes the PFMF.110.2 a great option for applications where power must be restored quickly.

The PFMF.110.2 is a great option for many applications since it offers high-performance protection and reliable self-resetting capability. Its current rating range, thermal time weighting curve, and low internal impedance make it ideal for protecting audio systems, motor controllers, and other sensitive electronic devices.
