Mersen fuses for the protection of transformers and distribution lines deliver overload and short circuit protection. These current-limiting fuses will melt at current that can be as low as 1.7 times the fuse current ratings up to its maximum interrupting rating. These fuses are designed to withstand the transformer magnetizing inrush current. They are single, double, triple or quadruple barrels 3 inch diameter (size D) with end mounts designed for bolting directly to equipment bus or terminal pads.

Features

• UL listed for compatibility with UL listed equipment
• Bolt-In mounting for direct connection to bus or terminals
• Current-limiting for superior equipment protection
• Non-venting for silent operation
• Metal embossed catalog number and manufacturing date for lasting identification
• Outdoor usage for the 9F62
• Blown-fuse indicator to give positive identification of open fuse
• Amp trap: 1 lb tripped force - 0.44 Inch
• 9F62: 0.125 lb tripped force – 0.20 Inch

Applications

• Protection for 5.5kV to 15.5kV transformers or distribution systems
