The flame-retardant UL94-V0 ABS IP54 1556 family of enclosures is inspired by the IP68 polycarbonate 1557 series. It features the same modern rounded corners and top face styling and introduces rectangular versions to complement the square formats derived from the 1557 series. IP54 sealed for general-purpose indoor use, the ABS material gives a lower price point than the polycarbonate used in the 1557, which is designed for installation outdoors and in aggressive environments. Self-tapping screws secure the lid to the base, for applications where repeated access is not required. There are multiple PCB mounting standoffs in both the lid and the base.

There are four square sizes from 80 x 80 to 200 x 200 mm and three rectangular ones from 120 x 80 to 200 x 160 mm. All are available in black, RAL 7035 grey and white and there are two heights: 45 and 60 mm for the smallest size and 45 and 70 mm for the larger ones. The enclosure is suitable for desktops when fitted with the supplied feet; it can also be wall-mounted with four visible brackets or two hidden ones. Also available as an option are 2 mm thick aluminium internal panels.
