Some of the products listed can be damaged by short circuits, motors jams, and surges from coming in contact with AC power lines. For that reason, the MF-RM series has been designed to provide overcurrent and overtemperature protection. By selecting the MF-RM series for a circuit, the customer can help improve overall product reliability and reduce costs associated with equipment repair. When resettable fuses replace one-time fuses, the warranty costs associated with replacing a blown fuse may be reduced significantly. This is particularly helpful in cases where fuses blow from nuisance tripping.
