Ceramic fast-acting fuse — 5 x 20 mm (6 x 30 T), 250 V — 10 pieces per rating Why customers choose this fuse Fast-acting protection: opens quickly on overloads to minimize stress and damage to downstream electronics and components. Durable ceramic construction: stands up to high temperatures and provides stable interruption characteristics under fault conditions. Broad compatibility: standard 5 x 20 mm form factor (listed as 6 x 30 T in the product reference) fits common panel holders and PCB clips for straightforward replacement. Multiple ratings in one package size: available in a wide range of current ratings so you can select the protection level that matches your circuit. Key specifications Size: 5 x 20 mm (6 x 30 T) Voltage rating: 250 V Current ratings available: 0.5 A, 1 A, 2 A, 3 A, 4 A, 5 A, 6 A, 8 A, 10 A, 13 A, 15 A, 16 A, 20 A, 30 A Pack quantity: 10 pieces per rating Type: ceramic, fast-acting Function and performance Designed to interrupt fault currents quickly to protect power supplies, control circuits, and sensitive electronics. Ceramic body provides improved heat resistance and mechanical robustness compared with glass fuses, especially in higher-temperature or vibration-prone environments. 250 V rating covers most low-voltage mains and industrial control applications. Practical use scenarios Power supply protection: Replace fuses in bench power supplies or SMPS modules to protect against short circuits and prevent damage to the supply or connected devices. Industrial control panels: Use in control kiosks, motor controllers, and PLC input/output modules where rapid interruption reduces risk to relays and downstream electronics. Consumer electronics and assemblies: Protect small appliances, chargers, and audio/video equipment that require fast clearing of faults to preserve sensitive components. Selection and installation tips Match the fuse current rating to the normal operating current of the circuit; choose the nearest higher standard rating only if it stays within conductor and component limits. Verify the 5 x 20 mm form factor fits your holder or panel; the product reference includes (6 x 30 T) for compatibility notes. Replace blown fuses only with the same type (ceramic, fast-acting), voltage (250 V), and current rating to maintain designed protection. This ceramic fast-acting fuse provides reliable, high-temperature-resistant overcurrent protection in a standard form factor and is supplied as 10 pieces per chosen rating.
