PTC Resettable Fuses are a common component in electrical circuits that are used to protect circuits against overload and short circuit conditions. The 0ZCK0010FF2G is an electrically-actuated PTC resettable fuse that is used to protect components such as motors, relays and transformers from overcurrent caused by either an overload or a short circuit. While its primary application is protecting motors, this type of fuse is also used in telecommunications and UPS systems, as well as consumer electronics or appliances. Its main characteristic is its ability to self-reset after an overload or short circuit has been cleared, allowing the protected component to continue to operate without interruption.

The 0ZCK0010FF2G is an example of a bi-metallic based PTC Resettable Fuse device. The bi-metallic element in this particular device is made up of a nickel alloy and an iron alloy laminate, each possessing a different thermal coefficient of resistance. This results in a temperature-responsive device with a predictable and gradual resistance increase when its temperature reaches its trip-point. At this point, the current is restricted to a safe level. When the fault is remedied or the load is reduced, the bi-metallic element cools until it returns to its original state at which point the current flow resumes.

The 0ZCK0010FF2G fuse is rated to work at a maximum voltage of 24V and can handle currents up to 10A. It is designed to trip at a hold current of 2.2 Amps, meaning the device must carry this current without tripping in a steady state. The trip time is up to 10 seconds with a typical value of 4, and the 30 second trip time is up to 5 seconds with a typical value of 2. Its surge rating is 100A with a maximum clearing current of 75A. The PTC Resettable Fuse also has a power rating of 2.4W and a thermal resistance of 2.3°C/W.

The 0ZCK0010FF2G is an ideal solution for controlling and protecting circuits and components from over-current conditions as its design allows for a gradual decrease in current flow. This prevents sudden drops in circuit operation, as well as premature component failure due to current surges. It is also easy to install and requires minimal maintenance, making it an attractive solution for any circuit protection application.
