Enclosure Rittal HD 4000.100 — stainless steel housing, grey, single-piece

Rittal HD 4000.100 is a stainless steel housing in a grey finish designed to protect electrical and electronic components in indoor or sheltered outdoor installations. Delivered as a single-piece enclosure, it provides a rigid, corrosion-resistant cabinet for mounting control gear, terminal blocks and small distribution components. The design supports routine maintenance and cleaning access when used with compatible accessories such as the HD wall spacer bracket.

Advantages

The stainless steel construction offers long-term resistance to corrosion and mechanical wear while the single-piece design simplifies installation and improves structural integrity. The grey finish provides a neutral, professional appearance that integrates with industrial and commercial environments. The enclosure accepts standard internal fittings for mounting a variety of components and, when combined with a wall spacer bracket, allows space behind the cabinet for cleaning and cable routing.

Key specifications

How to use

Mount the enclosure on a suitable wall or support structure using appropriate fixings and industry-standard installation practices. Fit internal mounting plates, DIN rails or component carriers as required, then install control devices, terminal blocks and wiring according to electrical schematics and safety standards. If additional clearance behind the enclosure is needed for cleaning or cable routing, install a compatible wall spacer bracket before mounting the housing.

Recommendations

Ensure that all installations comply with local electrical regulations and standards. Use corrosion-resistant fasteners and suitable seals at entry points to maintain environmental protection. Regularly inspect gaskets and mounting hardware and clean the area behind the enclosure if a wall spacer bracket is used to prevent accumulation of dust and debris.
