Protistor® size 122 aR , 2000VDC
Mersen DC offers provide a very high performing protection for railway power circuits. Mersen DC Semiconductor fuse-links were developed to provide improved performance required by today's new DC equipment. These fuse-links are typically operated in extreme environment more than other fuse type, have lower I2t to minimize damage to protected components on short circuits, lower watts loss and longer life time.
