PTC Resettable Fuses are electronically activated devices that are designed to protect machines, buildings, and other equipment against electrical overcurrents. The PTC Resettable Fuses are able to protect against both continuous and non-continuous faults or overloads. In addition to the primary overcurrent protection, these devices are also used to trip the system when a fault or overload is detected. This type of fuse is generally low in voltage drop, and is a robust design.

The PTS12066V200 is a varistor type of PTC Resettable Fuse that is designed to protect against overvoltage and overcurrent faults. It is rated at a 4A 30V DC maximum continuous current with a peak current of 16A, at 125à °C. The device has a short circuit breakdown voltage of greater than 10VAC, and is designed to reset after 4-5 times the set over-current level has been experienced.

The application field of PTS12066V200 includes, but is not limited to, communications, consumer electronics, computer, and industrial equipment. In communications, this type of fuse is commonly used in cable telephones, just like the FTTH broadband distribution box. In consumer electronics, these fuses can be used in routers, LED displays, as well as notebook computers. In industrial electronics, this fuse can be used in high power LED drivers, UPS power systems, and electronic ballasts. It is also suitable for AC/DC use.

The working principle of PTS12066V200 is quite simple. The heat generated from the fault current flow is absorbed by the thermally activated PTC element. When the temperature reaches the predetermined value, the element switches from low resistance to infinity, thus limiting the current flow. The device then needs to be manually reset after the fault has been removed in order for it to switch back to its low resistance state. If the fault current is not removed, the device will stay in its high-resistance state, thereby enabling the overcurrent condition to be detected and safety maintained.

The PTS12066V200 is a cost-effective and reliable way to protect equipment from electrical overcurrents. It is able to accurately detect and react to both continuous and non-continuous overcurrents. It is a low voltage drop device, and is available in a wide variety of designs for various applications. It is also simple to use, and easy to reset, allowing for quick protection without time-consuming troubleshooting.
