Protistor® size 300 aR, 2400VDC
Mersen DC high performance power fuses were developed to provide superior protection for railway power circuits. These fuses are typically operated at more elevated temperatures than other fuse types. They have lower I2t to minimize damage to components in case of short circuits, and have lower watts loss and longer life.
