PTC resettable fuses, also known as polyfuses and thermistor fuses, are a type of temperature-sensitive fuse typically used to protect circuits from current overload. When current reaches a certain level determined by the designer of the product, the PTC will heat up and open the circuit to prevent excessive current flow and protect the circuit from damage. This type of fuse is different from the standard fuse, which must be replaced after it has been triggered and is usually made of a thin wire.

RHE1500 is an electronic device known as a resettable fuse. It is designed to automatically protect the system from overcurrent faults and will reset itself after the fault condition is cleared. RHE1500 is based on a positive temperature coefficient (PTC) thermistor and has a trigger current of 1.5A. Its main characteristic is that its trigger point is always the same, so the user doesn’t have to adjust the trigger current manually. The device has excellent temperature cycling performance, fast overcurrent response time, and is cost effective.

RHE1500 has a wide range of application fields, including temperature protection, circuit protection, motor protection, electric power tools protection, and energy efficient lighting device protection, etc. This device can be used in automotive, medical, consumer, and other industries for overcurrent protection. It is designed to be surface mounted, and it is easy to install and use.

The working principle of the RHE1500 is based on the temperature-sensitive properties of a PTC thermistor. When the current passing through the thermistor reaches a certain level, it heats up until its resistance rises sharply, opening the circuit. When the current levels off below the trip level, the device will cool down and the resistance will decrease again, allowing it to switch back on. The trip current is determined by the user and depends on the application of the device.

RHE1500 is a versatile and cost effective solution for overcurrent protection. It features an excellent temperature cycling performance, fast response time, and no manual adjustment required. Its wide range of applications meets the requirements of various fields, and its easy installation makes it a popular choice for protecting various circuits.
