Description

The Mercury T2A is a 6 x 32mm slow blow fuse rated at 2A and 250V, designed to tolerate brief inrush current surges before blowing under sustained overload conditions. The time-delay element inside the glass tube allows the fuse to ride out momentary power spikes from motors starting, transformers energising, or capacitors charging, while still protecting the circuit from prolonged overcurrent faults.

These fuses are used in audio amplifiers, low-voltage lighting transformers, CCTV power supplies, and electronic equipment where switching on draws a higher current than continuous operation. The 6 x 32mm cartridge format is a standard size for fuse holders in UK and European equipment, fitting ceramic or panel-mount holders that accept this dimension. The glass body allows visual inspection of the internal element without removing the fuse from the holder.

The IEC approval confirms compliance with international standards for fuse construction and performance. Each fuse is marked with the rating and breaking capacity on the metal end cap. The slow blow characteristic means the fuse takes longer to blow than a fast-acting equivalent at the same current rating, reducing nuisance blowing during equipment startup.

Frequently Asked

What's the difference between slow blow and fast-acting fuses?

Slow blow fuses tolerate brief current surges above their rated value before blowing, allowing equipment with inrush current to start without nuisance fuse failure. Fast-acting fuses blow almost immediately when current exceeds the rating, giving tighter protection for sensitive electronics with no inrush.

What voltage rating does this carry?

The Mercury T2A is rated at 250V. This is the maximum voltage the fuse can safely interrupt when it blows under fault conditions.

Will this fit standard 6 x 32mm fuse holders?

Yes. The 6 x 32mm dimension is a standard cartridge fuse size and fits ceramic panel-mount holders, inline holders, and PCB-mount clips designed for this format.

How do I check if the fuse has blown?

The glass body allows you to see the internal wire element. If the wire is broken or the glass is blackened inside, the fuse has blown. For certainty, test with a multimeter on continuity mode across the two end caps.
