1.5A 6.3x32mm Big Glass Fuse - 1/4" x 1-1/4" Fast-Blow Fuse (Pack of 3)

Product Description The 1.5A 6.3x32mm Big Glass Fuse is a high-reliability safety component designed for precision circuit protection. Often referred to as "Big Fuses" or 1-1/4 inch fuses, these are significantly larger than standard 5x20mm variants, offering better heat dissipation for sensitive electronics. With a 1.5-Amp rating, they provide a robust safety barrier for power supplies, specialized audio equipment, and industrial controllers, ensuring the circuit is broken instantly during an overcurrent event.

Key Features

• Precision Low-Current Protection: Specifically rated at 1.5A to protect delicate components that cannot withstand moderate surges.

• Large Format Stability: The 6.35x32mm body provides a larger surface area for superior thermal management during continuous operation.

• Instant Trip Response: Fast-acting filament design interrupts the current flow immediately when the 1.5A threshold is exceeded.

• Clear Visual Diagnostic: Transparent glass tube housing allows for rapid identification of a blown fuse without a multimeter.

• Professional Grade: Nickel-plated brass end caps resist oxidation and ensure a low-resistance connection.

Technical Details

• Breaking Capacity: Engineered to safely handle fault currents in 250V AC environments without shattering.

• Filament Precision: Calibrated wire alloy ensures accurate 1.5A triggering for high-sensitivity circuits.

• Response Speed: Classified as Fast-Blow (F), reacting significantly faster than time-delay fuses.

• Insulation Properties: High-quality glass body ensures complete electrical isolation once the internal link is severed.

• Mechanical Standards: Complies with standard North American large-cartridge fuse dimensions (1/4" x 1-1/4").

• Operating Temperature: Maintains accurate current ratings in environments from -20°C up to +85°C.

• Labeling: End caps are clearly embossed with "1.5A 250V" for permanent and easy identification.

• Mechanical Strength: Constructed to withstand minor mechanical shocks common in industrial equipment.

• Storage Stability: Nickel plating ensures caps remain free of oxidation during long-term storage.

• Dielectric Strength: Capable of withstanding 500V AC across the open caps once the fuse has blown.

• Internal Resistance: Minimized cold resistance to ensure negligible voltage drop across the fuse link.

• Circuit Safeguard: Protects expensive control boards and logic circuits by failing first under fault conditions.
