PTC Resettable Fuses are integral components that are commonplace in hundreds of industrial and consumer-level applications, providing an extremely efficient source of protection against electrical overloads and short-circuits. As their name suggests, these fuses use a thermally sensitive PTC element to blow a circuit’s power and reset itself automatically following a period of time once the load has been removed. Their main benefit over traditional fuses is that they require no replacement, eliminating repetitive replacement labor and cost. They also provide a more reliable method of overload protection since their resetting feature, avoids the risk of incorrect wiring or repeat faults.

The RUE400-1 Resettable Fuses is a series of compact yet powerful resettable fuses that offer circuit protection for applications operating at up to 400V. The RUE400-1’s robust construction and versatile design enable it to be used in various industrial, consumer and automotive applications across the world. The RUE400-1 is designed around a single PTC thermistor element which is connected in series with the protected circuit. When the load on the protected circuit exceeds the device’s rated current, the increased energy generated by the PTC thermistor causes the internal circuit breaker to trip and open the protected circuit.

The resettable nature of the device is enabled by the ability of the thermistor to cool rapidly and reset, meaning that no manual intervention or reset is required. Once the overload has cleared and the temperature of the device returns to a safe level it re-closes the protected circuit. This self-resetting feature provides system stability and greater reliability as it helps to avoid the risk of incorrect wiring or repeat faults.

The RUE400-1 also includes built-in internal temperature limiting circuitry that will trip the device open if the device\'s temperature exceeds a certain limit. This feature helps to prevent the device from over-heating or becoming damaged due to high temperatures. The RUE400-1 is available in a variety of different sizes and ratings to ensure that it can be used in a range of specific applications.

RUE400-1 PTC Resettable Fuses are a cost-effective solution for protecting pumps, motors, transformers and small lines from short-circuits and overloads. They feature an ultra-low current response which allows them to provide protection even for consecutive short-circuit events. They are also resistant to moisture and corrosion, making them an ideal choice for applications in harsh environments. Additionally, the design of the RUE400-1 allows it to be easily integrated into existing electrical systems, ensuring a reliable and secure connection.

The RUE400-1 is suitable for most applications requiring reliable circuit protection and with its small size and low power consumption it makes it an ideal solution for many power protection needs. Furthermore, their breaking capacity and resettable feature provides the perfect level of protection against accidental overloads and short-circuits.
