Description
Mersen USM Series UltraSafe Modular Fuse holders introduce a new level of safety for Midget 1-1/2" x 13/32" AC and DC-rated fuses up to 30 amperes. UltraSafe holders qualify as “Finger-safe” under IEC and DIN standards to an IP20 grade of protection, including fuse changing (with the flick of a finger). UltraSafe holders are available in 1, 2, 3 or 4 poles, with or without visual blown-fuse indicators in each pole. Multipole units can also be field assembled by ordering pin-tie handles. UltraSafe holders save up to 15% mounting space and any combination can be snapped onto 35mm DIN-rail for extra savings in panel building time. UltraSafe body material is tough and durable polyamide, with exceptional insulating properties.
Features
- Constructed with a durable, insulating polyamide body, this modular block features an IP20-rated "finger-safe" dead-front design that completely conceals live metal electrical contacts. By totally eliminating the risk of accidental shock during quick, tool-free fuse change-outs, you immediately safeguard your maintenance crews and keep your facility compliant with rigorous IEC, DIN, and OSHA workplace safety regulations.
- Engineered to handle demanding high-voltage environments, this 30-amp UltraSafe™ modular fuse holder safely manages both 800V AC circuits and critical 1000V DC loads. This heavy-duty capacity makes it an essential, highly reliable component for commercial solar arrays, actively preventing catastrophic overcurrent events in string combiners and inverters while ensuring strict code compliance for specialized alternative energy grids.
- Designed for a rapid, snap-on installation directly onto any standard 35mm DIN rail, this compact 1-pole footprint significantly optimizes valuable control panel real estate by up to 15%. Equipped with highly secure pressure plate terminals that easily accept #14 to #6 AWG wire, it drastically speeds up new control board building and routine retrofitting for automated manufacturing equipment and non-load disconnect switches.
- Perfectly accommodating standard 1-1/2" x 13/32" (10x38mm) midget-style AC and DC rated fuses, this versatile holder provides a precision-engineered fit to eliminate loose connections and hazardous electrical arcing. Capable of handling a massive short circuit current rating (SCCR) of up to 200kA AC and 100kA DC, it ensures robust, highly dependable overcurrent protection for everything from small industrial transformers to high-demand DC drives.
