PTC resettable fuses have become increasingly prevalent in recent years as a versatile and widely utilized safety device utilized in a variety of applications. The PFUF.110.2 is a ptc resettable fuse that is particularly designed to meet UL standard 4581 with respect to overcurrent protection applications. This article will discuss the application field of the PFUF.110.2 and its working principle.

The PFUF.110.2 is designed mainly for use in small electronic circuitry, incorporating particularly interference suppression. Unlike traditional fuse systems, the PFUF.110.2 acts in a unique way, in that it is resetable while the fuse wire of traditional systems is not. This makes the PFUF.110.2 ideal for circuit protection.

In terms of application field, the PFUF.110.2 is suitable for a wide variety of applications, such as LED lighting, consumer appliances, telematic applications, outdoor security lighting and other small electric circuitry etc. It provides effective over-current protection by detecting too much current flow and releasing a switch to disconnect the current supply, thus protecting the system from over-heating and current overload. The PFUF.110.2 has a wide range of voltage setting and current current setting, which enable it to be applied in many applications with different requirements.

The PFUF.110.2 fuse operates on the principle of thermal insulation. It works by controlling the current flow and temperature of the associated electronic circuitry. When temperature and current exceed the given threshold, the PFUF.110.2 fuse will detect and release a switch to disconnect the current supply. When over-current and over-temperature conditions are brought back to normal, the reset process will be triggered, and the PFUF.110.2 will be able to resume normal operation.

In summary, the PFUF.110.2 is a PTC resettable fuse that is designed to meet UL standard 4581 with respect to over-current protection. It is suitable for a wide range of applications, including LED lighting, consumer appliances, telematic applications, outdoor security lighting, and other small electric circuitry etc. It works via the thermal insulation principle, controlling the current flow and temperature of the associated electronic circuitry. When too much current flow and/or too high a temperature are detected, the PFUF.110.2 will release a switch to disconnect the current supply, thus protecting the system from over-heating and current overload.
