Product: Glass Tube Fuses — 250 V, 10 A, 6 x 30 mm, fast blow Key benefits Fast, reliable overcurrent protection: the fast-blow characteristic interrupts short bursts and overloads quickly to protect sensitive components. Clear visual inspection: the glass tube lets you see the fuse element at a glance so you can confirm a blown fuse without disassembly. Standard, compact size: 6 x 30 mm fits common fuse holders and replacement slots for many electrical devices. Simple maintenance: direct drop-in replacement with no modification required when you match voltage and current ratings. What it does and why you need it Function: interrupts current flow when the current exceeds the rated 10 A to prevent component damage, overheating, or fire risk. Compatibility: designed for use in electrical devices that require a 250 V, 10 A, 6 x 30 mm fast-blow fuse; use as a direct replacement for the same specification. Performance: fast-blow response is suited to protecting circuits with components that can be harmed by brief overcurrent events. Important attributes Rated voltage: 250 V Rated current: 10 A Size: 6 x 30 mm (standard glass tube fuse dimension) Type: fast blow Material: glass tube construction for visual inspection Practical use scenarios Replace a blown fuse in bench power supplies or laboratory equipment that specify a 6 x 30 mm, 250 V, 10 A fast-blow fuse. Protect small appliances, chargers, or power adapters that use a 6 x 30 mm glass fuse and require fast response to short transients. Service audio gear, test instruments, or lighting fixtures with compatible fuse holders that accept 6 x 30 mm, 250 V, 10 A fast-blow fuses. Safe use recommendations Always power down equipment before replacing a fuse. Replace with the same type and rating (250 V, 10 A, 6 x 30 mm, fast blow) to maintain intended protection. Inspect the glass tube for visible damage or discoloration before installation. This glass tube fuse provides straightforward, standard protection for electrical devices that require a 250 V, 10 A, 6 x 30 mm fast-blow fuse.
