10A 6.3x32mm Big Glass Fuse - CEI High-Quality Large Fuse (Pack of 20)

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.
