PTC resettable fuses are a type of self-reset safety device that protect electronic components, automation equipment, and other machines from damage due to electrical overloads. They offer a simple, cost-efficient, and reliable protection solution for manufacturers, suppliers, and customers alike. RTEF135-2 is a PTC resettable fuse which specifically designed for medium-power applications, offering superior fuse performance, outstanding durability, and superior repeatability over time. It is an ideal choice for high-current designs.

Application Field

RTEF135-2 is suitable for a wide variety of applications, ranging from general-purpose motor control, HVAC systems, power supplies, lighting system, and consumer electronics applications. It is designed to provide superior thermal protection in a wide range of voltage, current, and ambient temperatures. Moreover, it also can be used for motor control applications, as it not only offers excellent repeatability to meet the dynamic nature of the load but also provides superior thermal protection to prevent the motor from getting overheated.

Working Principle

The working principle of RTEF135-2 is simple and straightforward. When the current through the fuse exceeds a predetermined set point, the PTC material heats up and acts as a resistor, which limits the current flow through the fuse. When the current returns to a safe level, the resistor cools down and the circuit returns to its normal state. This process is repeatable and ensures that the fuse will reset itself after each and every over-current event, allowing for reliable and consistent protection of the circuit.

RTEF135-2 is a lot more effective than traditional thermal-type fuses, as they provide superior current limiting and thermal protection. They are also incredibly durable, offering dependable performance over time and providing an explicitly designed current-overload protection solution. This makes them an ideal choice for manufacturers when it comes to providing reliable and cost-effective protection to their circuits.
