Introduction to PTC Resettable Fuses

PTC (Positive Temperature Coefficient) Resettable Fuses, also known as PPTC (polymeric positive temperature coefficient) fuses, are a type of thermally-activated, self-restoring fuses. They are used in a variety of applications to provide resettable overcurrent protection.

Application Field of PTGLCSAS4R7K6B51A0

PTGLCSAS4R7K6B51A0 PTC Resettable Fuses are used as a protection solution for reducing the risk of fire and equipment damage due to overcurrent. They are ideal for use in a variety of consumer, automotive, and industrial applications including motor protection, computers, and power supplies.

Working Principle of PTGLCSAS4R7K6B51A0

PTGLCSAS4R7K6B51A0 PTC Resettable Fuses operate on the principle of thermally activated self-resetting. When the current flowing through them exceeds a predetermined rating, the temperature of the fuse gradually begins to rise. This heat will cause the fuse to melt and the current will be disconnected. Once the temperature of the fuse has cooled, it will return to its original state, ready to enjoy current.The use of a lower current setting limits the maximum current that the device can endure before it trips. The device also has a thermal loop that causes the heater to turn off when the thermal balance of the part has been reached and the current dissipate s. This makes the device reliable, as it can protect the device from both expected and unexpected high currents.

Conclusion

PTGLCSAS4R7K6B51A0 PTC Resettable Fuses combine the benefits of both electrical and thermal protection and are a simple solution for providing protection for various systems. They are particularly suitable for applications where current levels exceed the limits of standard overcurrent protection devices. To provide reliable and long-lasting protection, and to ensure that the devices will trip even in the presence of unexpected currents, these devices should be combined with other safety devices such as circuit breakers and fuses.
