Protistor® size 120 aR , 2000VDC
Mersen DC offers provide a very high performant protection for railway power and auxiliary 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 at more elevated temperature than other fuse type, have lower I²t to minimize damage to protected components on short circuits, lower watts loss and longer life. To complete these fuse-links Mersen recommende to use the standard microswitch (ref. G310023, MCR3E1-5N).
