Product Description The CEI 10A 6.3x32mm Big Glass Fuse is a robust safety component engineered for high-power electrical applications. Known as "Big Fuses" due to their 1-1/4 inch length, these are designed to handle significant energy surges that smaller fuses cannot. With a 10-Amp rating, this fuse acts as a sacrificial protector, instantly breaking the circuit during an overcurrent event to shield your industrial power supplies, high-torque motors, and heavy-duty machinery from catastrophic failure.

Key Features

  • High-Power Capacity: Rated for 10A, making it ideal for protecting large-scale robotics and industrial control systems.

  • Large Format Body: The 6.3x32mm glass housing provides a larger surface area for heat dissipation compared to the small 5x20mm fuses.

  • Rapid Fault Interruption: Fast-blow filament ensures that the power is cut immediately when dangerous current thresholds are reached.

  • Visible Diagnostic Link: Transparent glass allows for a quick visual check to see if the internal wire is broken.

  • Bulk Maintenance Pack: Includes 20 pieces, providing a long-term supply for production lines and repair benches.

Technical Details

  • Breaking Capacity: Safely interrupts current flow in standard 250V AC circuits without shattering.

  • Filament Composition: Precision-calibrated metal link designed for consistent and accurate 10A triggering.

  • End Cap Material: Nickel-plated brass caps offer superior conductivity and resistance to oxidation and corrosion.

  • Voltage Compatibility: Fully rated for high-voltage AC systems and effectively used in high-current DC battery rails.

  • Response Speed: Classified as "Fast-Blow" (F), providing much faster reaction times than time-delay or slow-blow fuses.

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

  • Standard Dimensions: Follows the 1/4" x 1-1/4" (6.35mm x 31.75mm) industrial standard for large fuses.

  • Thermal Performance: Maintains its specified 10A rating across a wide temperature range from -20°C to +85°C.

  • Clear Marking: Metal end caps are permanently embossed with "10A 250V" for error-free identification.

  • Mechanical Strength: Robust construction is designed to withstand vibrations in mobile robotics and automotive builds.

  • Shelf Stability: Nickel-plated finish ensures the fuse remains ready for use even after years of storage in a toolbox.

  • Circuit Safeguard: Prevents PCB trace vaporisation and transformer burnout by failing first under load.

Prototyping and Engineering Tips from Robogears

  • 9V Battery Note: A 10A fuse is generally too high for standard 9V battery protection; consider a lower-rated fuse for small projects.

  • 18650 Power Arrays: For high-discharge 18650 Lithium battery packs, this 10A fuse is recommended for the main output rail to protect against major short circuits.

  • IC & Driver Support: Ideal for protecting the BTS7960 43A Motor Driver or high-power Step-Down Buck Converters from excessive current draw.

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

  • Related Products: We recommend pairing these with our Big Fuse Holders and 14 AWG Silicone Wire for a professional and safe high-current setup.

Package Includes

  • 20 x 10A 6.3x32mm Big Glass Fuses (CEI Brand).
