Tenso manufactures high-breaking ceramic cartridge fuses in 5×20 mm and 6×30 mm, fast-blow (F) and time-lag (T), for appliances, power supplies and any circuit whose prospective fault current is too high for a glass body. A ceramic body — often sand-filled — quenches the arc and gives the higher breaking capacity those circuits demand. You can step a glass fuse up to ceramic of the same size, current and voltage; never drop below the circuit’s fault level. For higher-power circuits, see industrial & HRC fuses. Ratings are indicative; confirm against the datasheet.

FAQ
Ceramic Fuses (High-Breaking) — questions buyers ask
Glass vs ceramic — what's the real difference?
Breaking capacity. Glass lets you see a blown element and suits low fault-current electronics; ceramic (often sand-filled) gives a much higher breaking capacity for higher fault-current circuits.
Can I replace a glass fuse with a ceramic one?
Yes, if the size, current and voltage match — a ceramic body simply adds breaking capacity. Don't go the other way and drop below the circuit's fault level.
What size is a 6×30 fuse?
6 mm × 30 mm body. It must match your holder or clip; 5×20 mm is the smaller, more common size.
