Electrical enclosure Rittal 9521.000, polyamide/polycarbonate, IP66, 254×111×180 mm

Rittal 9521.000 is a compact electrical enclosure made from fibre-glass reinforced polycarbonate with a polyamide base and an option of a grey or transparent cover. The enclosure provides IP66 protection and measures 254×111×180 mm (width × depth × height). It is intended to house electrical components and terminal blocks for indoor or outdoor installations where dust-tight sealing and protection against powerful water jets are required.

Advantages

The combination of polyamide and fibre-glass reinforced polycarbonate delivers high mechanical strength and resistance to impact and harsh environments while keeping weight low. IP66 rating ensures protection against dust ingress and powerful water jets. A transparent cover option allows visual inspection of mounted components without opening the enclosure. Compact external dimensions make the enclosure suitable for space-constrained installations and facilitate easy mounting and routing of wiring.

Suitable for

• Housing small control components and terminal blocks
• Outdoor junction boxes exposed to rain and splashes
• Indoor instrumentation and control panels in industrial settings
• Distributed control points in machine rooms and service cabinets

Key specifications

• Material: polyamide base with fibre-glass reinforced polycarbonate cover
• Protection class: IP66 (dust-tight, protection against powerful water jets)
• External dimensions (W × D × H): 254 × 111 × 180 mm
• Cover options: grey or transparent
• Suitable for mounting electrical components and terminal blocks

How to use

Mount the enclosure on a suitable surface using the integrated mounting points or external brackets, ensuring correct orientation and secure fastening. Route cables through appropriate cable entries or glands and fit cable seals to preserve the IP66 rating. Install electrical components and terminal blocks onto the internal mounting surface or DIN rail if applicable, following wiring diagrams and safety standards. Close the cover and secure the fasteners to restore full protection before energising the circuit.

Recommendations

Use appropriate cable glands and sealing accessories rated for IP66 to maintain the enclosure's protection level. For installations in direct sunlight or near heat sources, select the grey cover to reduce UV transmission; use the transparent cover where visual inspection without opening is required. Periodically inspect seals, fasteners and the cover for damage and replace components as needed to ensure ongoing protection.
