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
- This modular block features fully recessed contacts that earn a strict IEC IP20 finger-safe rating, preventing accidental contact with live components. This robust physical barrier gives panel builders and maintenance crews total confidence while working inside tight electrical enclosures or managing quick fuse replacements.
- Equipped with built-in visual LED indicator lights on each pole, this holder instantly illuminates when a fuse blows, removing all guesswork from circuit diagnosis. By accelerating fault identification in complex control panels, it slashes costly maintenance tracking time and helps restore critical factory operations without delay.
- Engineered with a formidable Short Circuit Current Rating (SCCR) of 200kA at 600VAC/VDC, the US3J3I protects downstream motor circuits and transformers from explosive electrical faults. This exceptional mitigation threshold safeguards delicate automated equipment while maintaining your control panel’s code compliance under demanding industrial conditions.
- Designed with a versatile, universal 35mm DIN-rail mount and an innovative open-stay latching mechanism, this compact 3-pole unit snaps effortlessly into place. The specialized latch remains open automatically, allowing electricians to slide, re-position, or remove the holder along the rail smoothly without the typical frustration of rigid, standard locking clips.
