When would you use a PTC fuse?
A PTC resettable fuse is a protection device only intended to operate during overcurrent and/or overtemperature events that are not normal operation and are generally undesired conditions. They are not intended to be a switch that operates numerous times in normal operation.
What is current for PTC?
(operating) current rating for PTCs can be up to 14A while the maximum level for fuses can exceed 30A. upper limit for a PTC is generally 85°C while the maximum operating temperature for fuses is 125°C.
Are there resettable fuses?
PTC Resettable Fuses are designed to stop current flow when it exceeds a certain limit (overcurrent protection). The Fuses work by increasing its resistance as its temperature rises due to the current increase.
How do I reset my PTC fuse?
The general procedure for resetting the device after an overload has occurred is to remove power and allow the device to cool down. When a PPTC is in a “tripped state” it protects the circuitry by limiting the current flow to a low leakage level.
How do resettable fuses work?
PTC resettable fuses are a step-up from one shot fuses. When a short circuit occurs, they heat up and transition from a low resistance state to a high resistance state. Allowing them to cool down (typically by removing the power) resets them to the low resistance state.
How PTC resettable fuses work?
Resettable fuses are designed and made of patented novel polymeric PTC material in thin chip form. Upon fault current being removed, the resettable fuse cools and its resistance drops to the original extremely low value. The resettable fuse is “reset” and allows the current through the circuit again.
What happens when a fault is removed from a PTC fuse?
Once the fault is removed, the power cycled through the PTC fuse will return to its normal low resistance state. You can access 3D STEP files of our resettable PTCs below, under Design Files.
