fuses,PPTC,resettable fuses,circuit breaker

PPTC and fuses both do the same job: protecting electronic circuits from overcurrent related issues. The difference is that the fuse must be replaced after tripping, while PPTC can reset itself. PPTC can handle sudden overcurrent events without the need for replacement.

PPTC and fuses both react to excessive current by generating heat, but they react in different ways. The fuse melts and breaks, completely interrupting the current, while PPTC limits the current by changing from a low resistance state to a high resistance state as the temperature increases. In short, if it is necessary to stop the current to fully protect the equipment, fuses are preferred. On the other hand, PPTC is typically used to anticipate situations where overcurrent events frequently occur, and it is crucial to maintain a constant system uptime at a lower service cost. They are also useful in remote or hard to reach places where replacing fuses is challenging.

Both circuit breakers and resettable fuses can ensure circuit safety. A circuit breaker is an electromechanical device designed to "trip" or disconnect contacts when the current exceeds the rated value, stopping the current and preventing damage to electrical equipment or wiring. After the circuit breaker trips, it can be reset through the switch. Circuit breakers are an important component of any power distribution system. The resettable fuse (PPTC) performs a similar function, tripping if the current exceeds the rated value. The difference is that when there is no longer an overcurrent situation, the resettable fuse will automatically reset. When the circuit breaker trips, the current is completely cut off, while the resettable fuse may still allow small currents to pass through.

What are the Differences in Performance and Applications between Slow Blown Fuses and Fast Blown Fuses?

The main difference between slow fuse and fast fuse is its ability to withstand instantaneous pulse current, which means that it can withstand the impact of surge current when switching on and off the machine without action, thus ensuring the normal operation of the equipment. Therefore, slow fuse is often referred to as surge resistant fuse. From a technical perspective, slow melting fuses have a large melting heat value of I2t, and the energy required for fuse melting is relatively high.

Why Do Fuses Have High Resistivity

A fuse is a wire made of lead antimony alloy with a lower melting point and a lower resistivity. The more voltage constant resistance can be compared, the more it can detect micro current resistance that exceeds the working range. A high current is required to fuse the resistance, which can burn out the electrical appliance and prevent it from melting. Some principles use the current thermal effect fuse to control the current flow and allow the current to flow.
