Mersen/Ferraz Shawmut TR7R Tri-Onic Fuse – Class RK5, 7A, 250V AC / 160V DC, Time-Delay (Lot of 5)

The TR7R is a dual-element fuse that provides a minimum of 10 seconds of time-delay at 500% of its rated current. This "slow-blow" characteristic makes it a standard choice for protecting AC motors against overloads and short circuits. As a Class RK5 fuse, it is highly current-limiting and features a rejection-style design to prevent the use of lower-rated, non-rejection fuses in critical safety applications.
