PTC Resettable Fuses are an important part of electrical circuit protection technology. They provide a reliable and efficient way of preventing high voltage and current surges from damaging sensitive electrical components. The MF-RHT1000-0 from Power Tronics is one of the latest additions to the PTC Resettable Fuses range. It offers the most advanced protection against high voltage and current surges of any current PTC available.

This device is used in a variety of applications including over-current protection, over-temperature protection, short circuit protection, and ground fault protection. It can be used in automotive, marine, industrial and consumer electronics applications, as well as a variety of other situations that require circuit protection.

The MF-RHT1000-0 is a two-pole resettable thermal cutoff. It is designed to provide protection from overloads, short-circuits, and over-temperature conditions. The device contains two over-current sensing elements that activate when a current flow greater than the rated value is detected. When this occurs, the device will trip and disconnect the circuit, preventing further damage or injury.

The operating principle of the MF-RHT1000-0 is based on a pair of current sensing elements, which are thermally coupled. When the rated current is exceeded, the thermal energy generated by the current is transferred to the thermal element, causing it to expand. This expansion causes an increase in resistance, which in turn trips the device, thus disconnecting the circuit and preventing further damage.

The resettable thermal element is normally in the open circuit state, and can only be reset once the fault has been removed. Unlike other PTCs, the MF-RHT1000-0 has a unique ‘latching’ feature which allows the device to maintain its trip state until manually reset. This feature can be very beneficial in preventing further damage in some applications.

The MF-RHT1000-0 is also highly reliable and provides excellent durability in harsh environments. With its high temperature rating of up to 175°C, it can withstand temperatures well above those required for normal operation. It also has a lifetime of up to 3,000 cycles, and a wide operating temperature range of -40°C to125°C.

In conclusion, the MF-RHT1000-0 is an ideal choice for a wide range of applications that require circuit protection. Its unique features make it an excellent choice for demanding applications, and its reliability and durability ensure long-term protection in harsh conditions.
