RTEF120

PTC Resettable Fuses are designed to protect electrical circuits from damages caused by too high or too low currents. By utilizing a thermistor with highly sensitive temperature accuracy, these fuses monitor the current of an appliance and trip once the current exceeds a preset limit. In addition, they can be reset quickly, providing circuit protection until the problem is resolved.

The RTEF120 is a PTC Resettable Fuse which incorporates a dual connection design, allowing more precise current measurements and control. It is designed for use in various industrial and commercial applications, providing reliable protection for motors, resistors, wiring harnesses, power controllers, and other electrical components in a wide variety of conditions.

The RTEF120’s working principle is straightforward. It contains a thermistor, which is a type of resistor that changes its resistance depending on its temperature. When power is applied, the thermistor heats up. As the temperature rises, the resistance of the thermistor increases, limiting the current and protecting against overcurrent. Once the current is above the preset threshold, the fuse trips, breaking the circuit.

The RTEF120 is designed to reset itself once the temperature has cooled. This is done via a simple switch located inside the fuse that disconnects power when the preset temperature is reached. Once the temperature has cooled, the switch is then re-engaged, restoring power and resetting the line. This process allows the RTEF120 to provide quick, reliable protection and eliminates the need for replacements.

The RTEF120 is a versatile and reliable PTC Resettable Fuse which is ideal for use in commercial and industrial applications. It is designed to trip and reset quickly in order to protect against overcurrents and other problems, and its dual connection design allows for more precise measurements and control. By utilizing this technology, users can rest assured that their circuits are protected from damages caused by too high or too low currents.
