20MM 5ASB SLOW BLOW FUSE

High-Performance Surge Protection: 20mm 5A Slow Blow Glass Fuse (5ASB) 

Ensure the safety and longevity of your high-power electronics with our 20mm 5A Slow Blow Glass Fuse. Also known as a "Time-Delay" or "T-Type" fuse, this component is specifically engineered to handle brief, high-intensity inrush currents without breaking the circuit. If a sustained overcurrent occurs, the fuse will reliably melt to prevent fire hazards and catastrophic damage to your equipment.

Key Performance Features:

• Advanced Time-Delay Technology: Features a coiled internal element designed to absorb temporary power spikes common in motors and large power supplies.

• Reliable 5A Current Rating: Calibrated to provide optimal protection for devices with a standard 5 Amp operating requirement.

• Standard 20mm Small Format: Compact 20mm length fits perfectly into standard electronic fuse holders, clips, and blocks.

• Transparent Glass Construction: Allows for instant visual inspection of the fuse status for efficient troubleshooting.

• High-Conductivity End Caps: Constructed with precision nickel-plated metal caps to ensure a secure, low-resistance electrical connection.

Why Use a 5ASB Slow Blow Fuse?

Devices like subwoofers, professional amplifiers, and motorized appliances often experience a massive surge of electricity the moment they are switched on. A standard "Fast Blow" fuse would snap instantly under this pressure. Our Slow Blow (5ASB) fuse provides the necessary delay to allow for these startup surges while still maintaining a critical safety barrier against actual electrical faults.

Technical Specs:

•  Fuse Type: Slow Blow

• Current Rating: 5 Amps (5A).

Top 3 Customer Questions & Concerns ‍

1. Can I use a 5A Fast Blow fuse instead of this one?

   • It is not recommended. In devices that require a Slow Blow fuse, a Fast Blow equivalent will likely "nuisance blow" immediately upon startup due to the initial power surge.

2. What does "5ASB" stand for?

   • "5A" indicates the 5 Amp current limit, and "SB" stands for "Slow Blow," indicating its time-delay characteristics.

3. How can I tell if the fuse is blown?

   • Look through the glass tube; if the coiled wire is broken or if there is dark discoloration (charring) inside the glass, the fuse has successfully protected your circuit and must be replaced.
