Product Description The CEI 5A 6.3x32mm Big Glass Fuse is a heavy-duty circuit protection component designed for high-power electronic systems. Often referred to as "Big Fuses" or 1/4 inch x 1-1/4 inch fuses, these are significantly larger than standard 5x20mm variants and are built to handle higher energy surges. With a 5-Amp rating, they provide a robust safety barrier for industrial equipment, large power supplies, and automotive electronics, ensuring the circuit is broken instantly during an overcurrent event.

Key Features

  • Large Format Protection: The 6.3x32mm size provides a larger surface area for better heat dissipation in high-power circuits.

  • Instant Trip Response: Fast-acting filament design interrupts the current flow immediately when the 5A threshold is exceeded.

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

  • High Conductivity Caps: Features nickel-plated brass end caps that resist oxidation and ensure a low-resistance connection.

  • Professional Bulk Pack: Includes 20 pieces, ideal for industrial maintenance, laboratories, and large-scale DIY projects.

Technical Details

  • Breaking Capacity: Engineered to safely handle significant fault currents in 250V AC environments.

  • Filament Composition: Calibrated zinc or copper alloy wire for precise 5A current triggering.

  • End Cap Material: Nickel-plated brass for superior mechanical strength and corrosion resistance.

  • Voltage Compliance: Fully rated for 250V AC, and highly effective in lower voltage DC applications.

  • Response Speed: Classified as "Fast-Blow" (F), designed to react significantly faster than time-delay or "Slow-Blow" fuses.

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

  • Mechanical Standards: Complies with standard North American large-cartridge fuse dimensions (6.35mm x 31.75mm).

  • Thermal Range: Maintains accurate current ratings in operating temperatures from -20°C up to +85°C.

  • Labeling: Caps are clearly embossed with "5A 250V" for permanent and easy identification.

  • Long-Term Reliability: Designed to withstand minor mechanical vibrations without premature filament failure.

  • Storage Stability: Indefinite shelf life when kept in a dry, non-corrosive storage container.

  • Circuit Safety: Prevents costly damage to transformers, motors, and high-end power semiconductors.

Prototyping and Engineering Tips from Robogears

  • 9V Battery Systems: Even at lower voltages, use this 5A fuse to protect 9V Hi-Watt battery arrays from high-current discharge in case of a wiring short.

  • 18650 Series Packs: For high-discharge 18650 Lithium cells, this big fuse is recommended for the main power rail to prevent cell venting during a stall or short.

  • IC Protection: Ideal for shielding high-power motor drivers like the BTS7960 43A Driver when running at moderate 5A continuous loads.

  • Fuse Holder Note: Ensure you use the correct 6.3x32mm Big Fuse Holder; standard 5x20mm holders will not fit this size.

  • Related Products: We recommend pairing these with our Heat Shrink Tubing and High-Current 18 AWG Wire for a safe and professional power distribution setup.

Package Includes

  • 20 x 5A 6.3x32mm Big Glass Fuses (CEI Brand).
