Mersen TR35R Fuse Tri-Onic 250V 35A Time-Delay Class RK5, 0.81 Inch Diameter, 3 Inch Length

Description

Features

• Boasting exceptional current-limiting capabilities, the TR35R rapidly chokes off massive electrical faults before they can reach peak energy levels. This premium level of protection significantly minimizes let-through current, shielding your downstream breakers, contactors, and control circuits from catastrophic thermal and mechanical damage during a short circuit event.
• Rated for a massive 200,000 Amps AC and 20,000 Amps DC at 250 Volts, this Class RK5 fuse delivers ultimate overcurrent protection for demanding industrial environments. It easily handles high-fault current zones within service entrances, main feeders, and branch distribution panels, ensuring full code compliance and workplace safety.
• Designed with a strict physical rejection shape, this 3-inch ferrule-terminal cartridge fits perfectly into standard Class RK5 fuse blocks while preventing the dangerous installation of lower-rated or non-current-limiting legacy fuses. This built-in mechanical safeguard protects maintenance teams from configuration errors and maintains the strict engineering integrity of your panel design.
• Built with a high-strength fiberglass body and packed with industrial-grade silica filler, this fuse provides incredible dimensional stability and rapid arc quenching under extreme heat. It resists internal pressure and physical degradation in high-vibration plants, while the stamped metal date and catalog markings ensure permanent legibility for swift safety audits and field identification.
