Description

This 6 x 32mm T160mA slow blow fuse is a glass tube delay-action fuse rated at 160mA on 250V circuits. The slow blow characteristic allows temporary inrush currents and start-up surges to pass without blowing the fuse, while still protecting against sustained overcurrent. The glass tube construction makes the internal wire filament visible, allowing quick inspection of fuse condition without removing it from the holder.

Designed for low-current applications in audio equipment, lighting control circuits, small transformers, control panels and instrumentation where inrush currents at power-on would cause a standard fast-acting fuse to fail prematurely. The 6 x 32mm format fits standard ceramic and panel-mount fuse holders common in European equipment. The 160mA rating suits circuits drawing between 100-140mA continuous load with occasional peaks up to 300-400mA during transient events.

The fuse meets IEC 60127 standards for miniature fuses, ensuring consistent breaking capacity and operating characteristics across different batches. The nickel-plated brass endcaps provide corrosion resistance and reliable contact with fuse holder terminals. The delay-action response is achieved through a coiled wire filament with a thermal mass that takes several seconds to heat to breaking point under moderate overcurrent conditions, compared to the instant response of a fast-acting fuse.

Frequently Asked

What does 'slow blow' mean?

Slow blow (also called time-delay or T-rated) means the fuse tolerates brief overcurrent surges without blowing, typically allowing 2-10 seconds at 200% rated current before breaking. This prevents nuisance blowing during equipment start-up or motor inrush.

What size fuse holder does it need?

Any standard 6 x 32mm fuse holder will accept this fuse. Common types include panel-mount ceramic holders, PCB-mount clips and inline cable holders. Check that the holder is rated for at least 250V.

Can I substitute a higher-rated fuse?

No. Using a higher-rated fuse (e.g. 315mA or 500mA) removes the overcurrent protection the circuit was designed for and can result in component damage or fire risk. Always replace with the same rating specified by the equipment manufacturer.

How do I tell if the fuse has blown?

The glass tube construction allows visual inspection. A blown fuse will show a broken or discoloured wire filament inside the tube, often with a dark carbon deposit on the glass. An intact fuse shows a continuous wire running between the two endcaps.
