(1) Single Bussmann TCF25, 600V, 25 Amp (25A), Time Delay Class CF Fuse
Safe-touch time-delay, indicating UL Class J fuses are finger-safe fuses that tolerate temporary inrush currents without opening, which prevents nuisance-blowing from motor and equipment startups. They are commonly used to protect electrical panelboards, machinery disconnects, and industrial controls. Also known as plug-in cube fuses, they have a square shape that provides a small footprint for limited-space applications and makes them compatible with finger-safe Class J fuse blocks and holders to help prevent contact with energized parts. These slow-blow fuses open to disconnect an electrical circuit when exposed to sustained loads and short circuits. They have a visual indicator to make it easier to identify blown fuses for replacement.
