Description
Mersen UltraSafe Modular 600 Volt Fuse Holders for Class J fuses introduce a new level of safety and ease for installing or replacing Class J fuses. UltraSafe holders qualify as “finger-safe” to an IP20 grade of protection under IEC standards. The US3J accommodates 30A Class J or 22 x 58 mm French Ferrule* fuses. The US6J is for 60A Class J fuses. UltraSafe holders are available in compact 1, 2, or 3 pole units, with or without blown-fuse indicators in each pole. Multi-pole units can also be made up in the field by using the multiplepole Assembly Kits. All units have provisions for locking in the open position for safety during fuse changeouts or equipment servicing. US3J and US6J holders can be snap-mounted to 35 mm DIN-rail and they have a unique latch which will stay open to allow re-positioning of the holder in the future. UltraSafe body material is tough and durable polyamide. *Holder not UL listed when installed with French Ferrule fuses. RECOMMENDED FUSE USAGE: *US3J, US6J use with AJT, A4J, HSJ
Features
- Engineered specifically for standard 60A Class J current-limiting fuses, this UltraSafe™ fuse holder delivers a flawless, rejection-style fit. This physical safeguard prevents the accidental insertion of lower-rated or non-current-limiting fuses, ensuring your downstream industrial automation components and branch circuits remain strictly protected against catastrophic short-circuit events up to 200kA.
- Featuring a fully enclosed, finger-safe housing rated to IP20 standards under IEC 529, this fuse holder eliminates accidental contact with live electrical terminations. This design provides maximum safety for industrial electricians and panel builders during routine troubleshooting or testing, allowing for confident, code-compliant maintenance inside live control cabinets.
- Built as a unified, space-saving 3-pole assembly, this unit snaps directly onto standard 35mm DIN rails or mounts via traditional screw holes. Its compact footprint drastically reduces required backpanel real estate compared to traditional open-style block designs, making it an ideal choice for compact motor control centers (MCCs) and crowded HVAC control panels.
- Equipped with built-in, high-visibility neon indicator lamps on each pole, this holder instantly illuminates when a fuse opens. This feature removes the guesswork from diagnostic workflows, allowing facility technicians to immediately locate and replace the blown fuse without deploying digital multimeters, substantially lowering emergency repair times.
