Electrical enclosure Rittal 1674.600 IP66, 327×120×227 mm (W×D×H)

Rittal 1674.600 is an IP66-rated electrical enclosure with external dimensions of 327×120×227 mm (W×D×H). Constructed for protection of electrical and electronic components in industrial and outdoor environments, the enclosure resists dust ingress and powerful water jets while providing a compact housing for control units, terminal blocks and small junction boxes. Its enclosure geometry features inclined surfaces across the cabinet and cover to facilitate run-off and reduce accumulation of dirt and liquids. The design includes an all-round gap-free silicone seal and hygiene-compliant hexagon screw fasteners for secure closure and easier maintenance.

Advantages

The enclosure offers IP66 protection level to safeguard internal components against dust and powerful water jets, ensuring reliable operation in harsh conditions. Inclined surfaces of 3° on all sides and 10° on the cover support drainage and minimize contamination retention. The continuous silicone seal provides a tight barrier against moisture and particulates, while hygiene-compliant hexagon screw fasteners allow tool-assisted secure fastening and simple access for servicing. Its compact external dimensions make it suitable where space is limited without compromising protection.

Key specifications

How to use

Mount the enclosure on a stable surface or within a mounting frame appropriate for the installation location, ensuring the orientation preserves the inclined surfaces for effective run-off. Install internal mounting plates or DIN rails as required for the intended components, leaving sufficient clearance for wiring and ventilation. Fit components such as terminal blocks, relays or small control units using recommended mounting hardware and route cables through appropriate gland entries or pre-cut openings. Close the cover and secure it with the supplied hexagon screw fasteners, making sure the silicone seal sits evenly to maintain the IP66 rating.

Recommendations

For long-term protection, verify the integrity of the silicone seal after installation and after any cover removal. Use suitable cable glands or conduit fittings to maintain the IP66 rating at cable entry points. Avoid exposing the enclosure to chemicals or temperatures beyond the manufacturer's specified limits and consult Rittal documentation for material-specific and mounting guidance.
