Product Description The CEI 2A Fast-Acting Glass Fuse is an essential safety component designed for low-to-medium power electronic circuits. Measuring the industry-standard 5x20mm, these fuses are widely used in multimeters, small power supplies, and control boards. With a 2-Amp rating, it acts as a sacrificial protector, instantly breaking the circuit during an overcurrent event to shield your expensive microcontrollers and sensitive semiconductors from permanent damage.

Key Features

  • Instant Overload Response: Fast-acting filament design triggers immediately when current exceeds 2A, preventing heat buildup.

  • Transparent Diagnostic Tube: High-clarity glass allows for a quick visual inspection to confirm if the fuse has blown.

  • Reliable Conductivity: Nickel-plated brass end caps ensure a low-resistance connection and resist oxidation over time.

  • Standard Small Format: Compatible with all standard 5x20mm fuse clips, blocks, and panel-mount holders.

  • Bulk Laboratory Pack: Includes 20 pieces, perfect for stocking your workbench or for high-volume production needs.

Technical Details

  • Breaking Capacity: Safely interrupts current flow up to 250V AC without the glass tube shattering.

  • Filament Material: Precision-calibrated alloy wire designed for accurate 2A current triggering.

  • End Cap Finish: Nickel plating over brass provides excellent mechanical strength and environmental protection.

  • Voltage Compatibility: Fully rated for 250V AC, but also highly effective for 12V and 24V DC robotics circuits.

  • Response Characteristic: "F" (Fast-Blow) type, which is critical for protecting logic-level components that cannot tolerate surges.

  • Temperature Range: Operates reliably in ambient conditions from -20°C up to +85°C.

  • Insulation Resistance: Once blown, the glass body provides complete electrical isolation to prevent arcing.

  • Mechanical Standards: Complies with standard 5mm x 20mm (M20) miniature fuse specifications.

  • Marking: Caps are clearly embossed with "2A 250V" for permanent, error-free identification.

  • Vibration Resistance: Designed to withstand the mechanical vibrations found in industrial control panels.

  • Lead-Free Construction: Compliant with modern RoHS environmental safety standards.

  • Circuit Safety: Protects PCB traces from melting during a short-circuit event by acting as the weakest link.

Prototyping and Engineering Tips from Robogears

  • 9V Battery Use: For 9V Hi-Watt battery projects, a 2A fuse is the ideal protection level for small motor drivers like the L293D, preventing the driver from burning out if the motor stalls.

  • 18650 Series Monitoring: When building 18650 Lithium-ion packs, use this fuse for individual sensing wires or low-power output rails to ensure fire safety.

  • IC Protection: Highly recommended for protecting the input of Buck/Boost Converters and Arduino/ESP32 power rails from reverse polarity or sudden spikes.

  • Troubleshooting Tip: If your 2A fuse blows, use a Multimeter to check for a short between your VCC and GND rails before replacing it with a new one.

  • Related Products: We recommend pairing these with our 5x20mm Inline Screw-Type Fuse Holders and Digital Multimeters.

Package Includes

  • 20 x 2A 5x20mm Glass Fuses (CEI Brand).
