PTC (positive temperature coefficient) resettable fuses are field effect devices that resemble temperature sensitive components. These fuses can be extremely reliable for circuit protection and may reduce the need for mechanical components in a system. They have a very low risk of failure, and can be easily reset in the event of an overload. This makes them suitable for use in many different applications. The RXEF075-2 is a popular PTC resettable fuse that is used in a variety of applications. This article will discuss the application field and working principle of this device.

RXEF075-2 Application Field

The RXEF075-2 PTC resettable fuse is designed for over-current and short circuit protection of AC systems and DC equipment. It is primarily used for protection of residential and commercial electrical applications as well as consumer electronic appliance and automotive products. This particular fuse is capable of current rating up to 75A and voltage rating up to 690V AC/DC. It is an ideal choice for applications with high current and high temperature requirements. The RXEF075-2 is UL recognized for many of its applications, making it one of the most popular options for many manufacturers.

RXEF075-2 Working Principle

The RXEF075-2 has an intrinsic temperature sensitive element that is activated when necessary. When an over-current, short-circuit, or other abnormal conditions occur, the device will quickly heat up and activate a resetting process. During this process, the built-in thermal protection element will automatically cut off the circuit and won’t reactivate until the device has cooled down. This means that the device is only reset after it has cooled down and values have returned to normal. No manual resetting is required for this device, making it a safer and more reliable choice.

The RXEF075-2 also has a built-in pressure sensitive element that will cut off the circuit when a certain pressure threshold is reached. This is an optional feature that can be enabled or disabled. When enabled, it adds extra protection to the system by resetting the device when it detects a pressure overload.

Conclusion

The RXEF075-2 is a popular PTC resettable fuse that is designed for use in a variety of applications. It is UL recognized for many of its applications, making it an ideal choice for many manufacturers. The device has a built-in thermal protection element that automatically resets the circuit once it has cooled down, and it also has an optional pressure sensitive element that can be enabled or disabled. These features make it a very reliable and safe option for over-current and short-circuit protection of AC systems and DC equipment.
