Product Description The CEI 5A Fast-Acting Glass Fuse is a precision circuit protection component designed to safeguard electronic devices from overcurrent conditions. Measuring 5x20mm, this "small" format fuse is the industry standard for consumer electronics, power supplies, and small appliances. With a 5-Amp rating, it provides a reliable safety barrier, quickly breaking the circuit during a fault to prevent fire hazards and permanent hardware damage.

Key Features

  • Instant Overcurrent Protection: Fast-blow characteristic ensures the circuit is interrupted immediately during a spike.

  • Clear Visual Diagnostic: The transparent glass body allows for instant verification of a blown filament.

  • Corrosion-Resistant Caps: Nickel-plated brass end caps provide superior conductivity and long-term reliability.

  • Universal Compatibility: Fits all standard 5x20mm fuse holders, including panel-mount and inline types.

  • High-Volume Value Pack: Includes 20 units, making it ideal for repair shops, labs, and frequent prototyping.

Technical Details

  • Operating Principle: Utilises a calibrated metal wire that melts when current exceeds 5A for a specified duration.

  • Breaking Capacity: Engineered to handle standard household and industrial short-circuit currents safely.

  • Standard Dimensions: 5mm diameter and 20mm length, often referred to as "M20" or "Small" fuses.

  • Voltage Rating: Fully rated for 250V AC, making it suitable for both AC mains and low-voltage DC applications.

  • Response Speed: Fast-acting (F) design reacts significantly faster than "Slow-Blow" (T) equivalents.

  • Contact Material: High-conductivity brass with nickel plating to prevent oxidation in humid environments.

  • Thermal Range: Performs consistently across a wide temperature range of -20°C to +85°C.

  • Insulation Resistance: The glass body provides excellent electrical insulation after the fuse has blown.

  • Marking: Caps are clearly stamped with "5A 250V" for easy identification during maintenance.

  • Storage Life: Indefinite shelf life when stored in a dry, non-corrosive environment.

  • Vibration Resistance: The internal filament is secured to withstand moderate mechanical shocks and vibrations.

  • Safety Compliance: Manufactured to meet standard electrical protection benchmarks for miniature fuses.

Prototyping and Engineering Tips from Robogears

  • 9V Battery Use: In projects powered by a 9V Hi-Watt battery, use a 5A fuse to protect your wiring harness from melting if a motor or actuator stalls.

  • 18650 Cell Protection: When using 18650 Lithium cells in series, a 5A fuse is an excellent choice for medium-power robots to prevent battery venting during a short.

  • IC & Driver Safety: Ideal for protecting L293D or L298N Motor Drivers from drawing excessive current during heavy mechanical loads.

  • Troubleshooting Tip: If a fuse blows repeatedly, do not increase the Amp rating; check your circuit for a short-circuit or an overloaded motor.

  • Related Products: We recommend pairing these with our 5x20mm Panel Mount Fuse Holders and Digital Multimeters for accurate testing.

Package Includes

  • 20 x 5A 5x20mm Glass Fuses (CEI Brand).
