PTC Resettable Fuses: Introduction to RUEF600 Application Field and Working Principle

PTC Resettable Fuses, or Polyswitch Resettable Fuses, are a type of electrical protection device designed to provide protection against potential overloads or short circuits. Unlike traditional fuses, PTC Resettable Fuses are ‘self-healing’ devices that will not degrade or need to be replaced after an overload or short circuit has occurred. The RUEF600 series of PTC Resettable Fuses, manufactured by Panasonic, are a range of devices which are widely used in various applications due to their robust construction, fast operating times and reliable performance. This article will introduce the application field and working principle of the RUEF600 series.

Application Field

The RUEF600 series is particularly suited for use in applications which require fast response times in the event of an overload or short circuit. This is because the time it takes for the fuse to trip and break the circuit is considerably shorter than the time taken for a conventional fuse to blow. The RUEF600 series is also suitable for use in applications where frequent short circuits or overloads may occur, as the fuse is ‘self-healing’ and can be reset after a fault has cleared. The RUEF600 series is typically used in a wide range of consumer electronics and electrical equipment, including appliances, audio-visual equipment, computers, mobile phones and electronic testing equipment. The devices are also used in automotive applications such as automotive alternators and starter motors.

Working Principle

PTC Resettable Fuses, like traditional fuses, use a current-sensing element to detect when the current in the circuit has exceeded the device\'s rated current limit. When this occurs, the device will ‘trip’ and break the circuit. This limits the amount of current which is able to flow, thus preventing any further damage to the connected circuit. The PTC Resettable Fuse will reset itself after the fault has cleared. This is made possible by a combination of the device\'s thermally-activated PTC element and resistance element. When the overload or short circuit has cleared, the PTC element will cool down, and the resistance element will return to its normal resistance. This will allow the device to reset itself and allow current to flow through the circuit once again.

Conclusion

The RUEF600 series of PTC Resettable Fuses is a range of devices which are suitable for use in a wide variety of applications, from consumer electronics to automotive applications. The RUEF600 series is appreciated for its fast response times and reliable performance. This is made possible by its self-resetting mechanism, which uses a thermally-activated PTC element and resistance element to reset the device after an overload or short circuit has cleared.
