Description

The ABB 1SL0858A00 is the largest model in ABB’s smooth low-lid IP65 thermoplastic enclosure series, with external dimensions of 310 x 240 x 110 mm. This enclosure provides a substantial interior cavity for housing DIN rail-mounted switchgear, terminal wiring systems, power distribution components, or control assemblies requiring a sealed and protected housing. It is manufactured from halogen-free, self-extinguishing thermoplastic material that passes the 650°C Glow Wire Test, meeting the fire safety requirements demanded by modern electrical installation standards.

With IP65 protection certified to IEC 60529, the enclosure offers complete dust-tight construction and full resistance to water jets from any direction, making it suitable for demanding outdoor and industrial environments including water treatment plants, food processing facilities, offshore platforms, and general industrial plant rooms. The 1/4 turn screw lid mechanism enables swift access for installation and maintenance, and the smooth lid profile minimises the overall depth of the enclosure when wall-mounted, aiding installation in areas with limited working depth.

The 1SL0858A00 accepts ABB’s full range of thermoplastic enclosure accessories, including DIN rail mounting channels, multi-row terminal boards, cable gland plates, padlock attachments, and blanking plugs. Its generous 310 x 240 mm base allows the assembly of meaningful switchgear layouts within a single sealed enclosure. This product is widely used by panel builders, electrical contractors, and OEM equipment manufacturers who require a reliable, standards-compliant enclosure solution for protecting critical electrical and automation components in challenging service environments.
