15A 6.3x32mm Big Glass Fuse - CEI High-Quality Large Fuse (Pack of 20)

Product Description The CEI 15A 6.3x32mm Big Glass Fuse is a heavy-duty safety component designed for high-power electrical systems. These "Big Fuses" are significantly larger than standard electronics fuses, providing a more robust physical profile for industrial-grade protection. With a 15-Amp rating, this fuse acts as a high-capacity sacrificial link, instantly interrupting the circuit during a severe overcurrent or short-circuit event to prevent catastrophic failure of your equipment.

Key Features

• High Current Capacity: Rated for 15A, making it suitable for high-power motors, industrial power supplies, and automotive circuits.

• Large Format Heat Dissipation: The 6.3x32mm glass body allows for better thermal management under high-load conditions.

• Rapid Circuit Interruption: Fast-blow filament ensures that the power is cut immediately upon reaching dangerous current levels.

• Clear Diagnostic Inspection: Transparent glass construction allows you to verify a blown fuse visually without needing complex testing tools.

• Industrial Bulk Supply: Pack of 20 ensures you have ample replacements for mission-critical machinery and production lines.

Technical Details

• Breaking Capacity: Engineered to safely handle high-energy faults in 250V AC power systems.

• Filament Composition: Precision-calibrated metal alloy designed for consistent 15A triggering.

• End Cap Construction: Nickel-plated brass caps offer maximum conductivity and superior resistance to environmental corrosion.

• Voltage Compatibility: Optimized for 250V AC, but also highly effective for high-current 12V/24V DC battery systems.

• Response Characteristic: "F" type (Fast-Blow), providing essential protection for components that cannot withstand sustained overcurrent.

• Insulation Integrity: High-quality glass provides reliable electrical isolation after the internal link has severed.

• Mechanical Standards: Follows standard 1/4" x 1-1/4" dimensions, making it compatible with all large-format fuse holders.

• Thermal Range: Operates within specified tolerances in temperatures ranging from -20°C to +85°C.

• Embossed Markings: Caps are clearly stamped with "15A 250V" for permanent and accurate identification.

• Vibration Resistance: Designed to hold its settings even in heavy industrial environments with constant mechanical shock.

• Shelf Life: Nickel plating ensures the caps remain free of oxidation even during long-term storage in workshops.

• Safety Standard: Prevents PCB trace melting and transformer burnout by acting as the primary point of failure.
