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 with an IP20-rated touch-safe polyamide housing, the US3J3 prevents direct contact with live internal electrical contacts during routine operation or maintenance. This crucial safety feature protects facility technicians during field service, helping your shop floor meet strict OSHA and NFPA 70E electrical safety standards without requiring bulky external shielding.
- This 3-pole fuse holder is custom-tailored to accommodate standard 30-amp, 600V AC/DC Class J fuses (such as Mersen AJT, A4J, or HSJ series). Its precise, high-continuity clip design reliably secures your critical circuit protection, making it perfect for branch circuit isolation, commercial motor controls, transformers, and industrial heating loops.
- Boasting a robust 200 kA fault-current withstand rating, the US3J3 ensures your control panels remain structurally intact and code-compliant during severe short-circuit spikes. This elite protection tier minimizes catastrophic panel damage and mitigates downstream component failure, ensuring critical production lines experience minimal electrical infrastructure downtime.
- Featuring a heavy-duty, integrated DIN-rail latch system, this modular fuse block snaps cleanly onto standard 35mm rails without requiring specialized mounting hardware. The intelligent latch mechanism is designed to remain locked in the open position when needed, allowing effortless repositioning and rapid cabinet wiring layouts for control panel builders.
