Mersen DCT8-2 Fast-Acting Fuse

The Mersen DCT8-2 is a fast-acting cylindrical fuse rated at 8 A for 570 V AC circuits. It suits technicians and installers protecting semiconductor devices in solar arrays or industrial power equipment. The transparent body allows quick visual inspection of the element. It fits standard 13/32 in diameter fuse holders without rejection features.

Thermals Noise and Power Draw

The fuse operates silently with no moving parts and draws no power during normal operation. Its single-element design limits heat rise to the rated current level. Interrupt ratings reach 100 kA at 750 V AC and 50 kA at 1000 V DC for safe fault clearing. CE, CSA and UL recognition confirm compliance with recognised safety standards.

Replaces Bussmann PV-F and Littelfuse SPF

This DCT series fuse directly replaces Bussmann PV-F and Littelfuse SPF equivalents in existing holders. The jump is worth it when a non-rejection 13/32 in cylindrical fuse with 100 kA AC interrupt capacity is specified. Installers needing an indicating version or a different diameter holder should select an alternative series.

Questions about this item

How do I install the Mersen DCT8-2 fuse and what step is often missed?

Insert the cylindrical body into a compatible 13/32 in diameter holder until fully seated; the step often missed is verifying the holder is rated for at least 570V AC and the 100kA interrupt rating before restoring power.

What maintenance or replacement will the Mersen DCT8-2 fuse need later?

As a non-indicating, single-element fuse it requires no routine maintenance; after any overcurrent event the fuse must be replaced with an identical 8A DCT series unit because it cannot be reset.

What limit appears first on the Mersen DCT8-2 fuse under sustained use?

The 8A continuous current rating is the first limit; sustained current above 8A will cause the fast-acting element to open, interrupting the circuit at up to 100kA at 750V AC.
