🗎 Product description from the manufacturer spec sheet
The Mersen TRS20R Tri-Onic TRS-R is a current-limiting time-delay fuse rated 20A at 600V AC / 300V DC, Class RK5, with a 200kA AC interrupt rating. Its time-delay characteristics handle harmless motor starting and transformer inrush currents without nuisance opening, and the rejection-style design prevents replacement errors when used with recommended fuse blocks.
