Product Description The 15A Glass Fuse 5x20mm is a high-capacity safety component designed to protect electronic circuits from severe overcurrent and short-circuit conditions. These "small" format cartridge fuses are engineered to interrupt electrical flow instantly when the 15A threshold is reached. Featuring a transparent glass body for easy inspection and nickel-plated brass end caps for superior conductivity, this pack of 20 is an essential bulk supply for industrial maintenance and high-power prototyping.

Key Features

  • Instant Overcurrent Protection: Fast-acting response designed to save expensive downstream components from sudden spikes.

  • Transparent Diagnostic Tube: Clear glass allows for immediate visual confirmation of a blown internal filament.

  • Corrosion-Resistant Caps: Nickel-plated brass end caps ensure long-term reliability and low contact resistance.

  • Standard Small Format: Universal 5x20mm dimensions compatible with most standard fuse holders and PCB clips.

  • Bulk Maintenance Pack: Includes 20 units, providing a reliable supply for busy labs and production environments.


Technical Details

  • Breaking Capacity: Safely ruptures under fault conditions up to 250V AC without shattering the glass housing.

  • Filament Composition: Calibrated silver or copper alloy wire for precise and repeatable 15A triggering.

  • Response Speed: Classified as Fast-Blow (Type F), reacting within milliseconds to protect sensitive semiconductors.

  • Operating Temperature: Maintains stable performance in ambient conditions ranging from -55°C to +125°C.

  • Insulation Resistance: Once blown, the glass tube provides high electrical isolation to prevent internal arcing.

  • Voltage Compliance: Rated for 250V AC and effectively used in high-current DC battery distribution.

  • Internal Resistance: Extremely low cold resistance (mΩ range) to minimise power loss during normal operation.

  • Mechanical Strength: Robust construction designed to withstand standard industrial vibrations.

  • Marking: Caps are clearly stamped with 15A 250V for permanent and accurate identification.

  • Environmental Safety: Lead-free construction compliant with modern RoHS standards.

  • Mounting Versatility: Compatible with cylindrical fuse holders, through-hole clips, and inline carriers.

  • Quality Standard: Manufactured to meet universal electrical protection benchmarks for miniature fuses.

Prototyping and Engineering Tips from Robogears

  • High-Power Battery Safety: When prototyping with high-discharge 18650 cells, use this 15A fuse to prevent fire hazards during accidental short-circuit events.

  • Inrush Current Warning: Avoid using these fast-acting fuses for high-torque motors; for inductive loads, consider Slow-Blow variants to handle startup surges.

  • IC & Driver Protection: Ideal for shielding high-current motor drivers like the BTS7960 from catastrophic failure during mechanical stalls.

  • Circuit Placement: Always install the fuse on the Positive (Live) rail to ensure the entire circuit is de-energised upon fuse failure.

  • Related Products: We recommend pairing these with our 5x20mm Panel Mount Fuse Holders for a professional and secure installation.

Package Includes

  • 20 x 15A 5x20mm Glass Fuses.

Disclaimer: Images are for illustration purposes only. The actual brand markings or end-cap texture may vary by batch. Always ensure your circuit's total load does not exceed 15A before installation.
