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.

Prototyping and Engineering Tips from Robogears

  • 9V Battery Note: A 15A fuse is generally too high for standard 9V battery protection; it is better suited for Lead-Acid or High-Discharge Lithium arrays.

  • 18650 High-Power Packs: Essential for 18650 battery packs used in DIY electric vehicles or high-torque robotics, where stall currents can spike significantly.

  • IC & Driver Safety: Ideal for protecting high-current motor drivers like the BTS7960 43A Driver or high-power Buck Converters.

  • Holder Compatibility: This fuse requires a 6.3x32mm Big Fuse Holder; it will not fit into standard 5x20mm small fuse housings.

  • Related Products: We recommend using 14 AWG or 12 AWG Heavy-Duty Wire to handle the 15A current safely without excessive heat buildup.

Package Includes

  • 20 x 15A 6.3x32mm Big Glass Fuses (CEI Brand).
