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.

• Multiple body sizes and terminals or blades combination
• Very low I²t
• Extremely fast acting
• Eliminate all overloads
• Excellent cycling capability
