PTC resettable fuses are devices which use positive temperature coefficient of resistance (PTC) devices such as polymeric positive temperature coefficient of resistance (PPTC) or multi-layer thermistor (MLT) technology to provide reliable overload and short-circuit protection in a wide range of applications. The MF-RHT450-0 is a re-settable fuse designed to protect electronic circuits from damage resulting from overcurrents and short circuits.

The MF-RHT450-0 is IEC certified and UL recognized. It is primarily used for protection of medium voltage applications and can be used in high current applications up to 40A. The series is available in three different voltage ratings: 800V, 1000V, and 1200V. The MF-RHT450-0 is also available in two different configurations depending on the required reset voltage: auto resetting (200V) or manual resetting (180V).

The MF-RHT450-0 is a current dependent PTC resettable fuse that will help protect circuits from high current transients or faults. The PTC element is designed to open immediately when it senses a current greater than its rated current. Once the overcurrent condition has been cleared, the PTC element will reset, and the circuit return to normal operation. The MF-RHT450-0 is configured to open at approximately 180V and 200V. Based on the configuration, either manual resetting or auto resetting is achieved.

The MF-RHT450-0 can be used in a wide range of applications, such as automotive, appliance, consumer electronics, industrial control, and LED lighting. It is capable of protecting circuits from over-temperature, over-current, or over-voltage. The fuse\'s compact size and low profile make it ideal for applications where space is at a premium.

The key feature of the MF-RHT450-0 is its self-resetting capability. Thanks to the PTC device, when the fault current reaches the rated current, the PTC device will cut off the circuit and open the contacts. Once the fault current has been reduced or removed, the PTC device cools down and automatically resets the fuse, so the fuse can be used again. This eliminates the need for replacing the fuse after it has been activated, saving time and money.

The MF-RHT450-0 also has an additional feature which is a soft start function. This inhibits the current surge which can occur when the fuse is turned on. Once the current falls below the rated current, the PTC device will reset and the circuit will be protected. The PTC device provides fast fuse action and reliable protection while the soft-start function allows for more efficient operation.

The MF-RHT450-0 is an excellent solution for applications where protection is needed from over-current, over-voltage, and over-temperature. Its self-resetting and soft-start functions make it an ideal solution for a range of applications, from automotive and industrial to consumer electronics and LED lighting. The compact size and low profile make the MF-RHT450-0 an ideal choice for applications where space is limited.
