MF-RM Multifuse® PTC Resettable Fuses

Bourns MF-RM Multifuse® Polymer PTC Resettable Fuses provide overcurrent protection for AC mains circuits up to 240VAC. These fuses feature combined overcurrent and overtemperature protection in one device and help prevent components from having to be replaced after tripping. Bourns MF-RM fuses offer generally lower electromagnetic interference than bimetallic switches. These fuses are also faster than bimetallic switch designs. MF-RM series fuses are ideal for food blenders, coffee machines, HVAC, electric fans, blowers, and AC adapters.
