RLD60P185XF

PTC Resettable Fuses

PTC resettable fuses (also known as polymeric positive temperature coefficient or PTC) are designed to protect electronic circuits during overloads and short circuits. Unlike traditional thermal fuse or fuse devices, PTC resettable fuses are designed to reset themselves after the overcurrent is removed. This cycle of resetting and tripping can occur multiple times without having to replace the component.

The RLD60P185XF is a surface-mount resettable fuse rated at 60A at 125V AC current. It is constructed with a sturdy polymeric material that is able to withstand high temperatures and mechanical/vibrational shocks. The fuse has three lead pins for electrical connection. The shape and size of the fuse makes it ideal for use in various high-density application fields.

Application Field

The RLD60P185XF is suitable for a wide variety of application fields such as industrial control systems, power factor correction systems, motor control panels, solar power systems, inverters, UPS systems, and other power-related applications.

Working Principle

The working principle of the RLD60P185XF relies on two processes: trip current and reset current. When the device is subjected to a current level equal to or higher than its trip current value, it will automatically open up (trip) to interrupt the current flow and protect the device. Once the current is below the reset current value, the body material of the fuse component will gradually warm up to the reset temperature, allowing the device to reset.

Therefore, the RLD60P185XF is designed to activate its trip and reset functions in a temperature dependent way. By having such a feature, the user can be assured that the device is capable of protecting the circuit even during surges and overcurrents.

Conclusion

The RLD60P185XF is an ideal choice for use in a variety of applications due to its high surge current capability and temperature dependent reset characteristics. Its size and shape also make it suitable for high-density applications. Furthermore, the device can cycle between trip and reset multiple times without having to replace the component, thus saving time and money.
