Eaton 038555 CI44E-250 Iso-enclosure with metric pre-punchings content_copy

The Eaton CI44E-250 is a single empty housing made of polycarbonate, specifically designed for use in damp environments and as an ISO distributor housing. The housing features a shock-resistant construction and is rated to IP65, ensuring dust-tight and splash-proof conditions – ideal for outdoor use or in damp indoor areas. The lid closure is patented and incorporates a pressure equalization system, ensuring a secure and long-lasting seal without excessive internal pressure buildup. The cover is transparent smoke gray, while the plinth is finished in RAL 7035 gray, providing good visibility of internal components while maintaining visual harmony.

Applications

The CI44E-250 is suitable as a distributor or meter cabinet in industrial, commercial, and municipal installations, particularly where high mechanical stress and moisture protection are required. The design with hinged side panels allows for flexible use: the housing can be operated as a compact cabinet or converted into an open distributor housing by unfolding the side panels. This expands its application possibilities in electrical installations, especially for integrating distributors, fuses, or measuring devices.

Functions and Equipment in Detail

The housing is equipped with metric pre-punched openings for cable entries on all sides. The top and bottom cable entries include each 1x M50/32, 2x M40/32, 8x M25/16, and 2x M20. Each side panel features 1x M63/40, 6x M25/16, 10x M20, and 2x M16. These diverse openings allow for flexible and quick installation of cables of various diameters. Mounting brackets on the rear facilitate wall mounting. The lid closures are sealable, ensuring secure and documentable sealing for monitoring or inspection purposes.

Technology Explained Simply

The use of polycarbonate as material provides high mechanical strength and weather resistance. The IP65 protection rating safeguards against dust and water spray from all directions, making the housing suitable for use in damp or wet environments. The integrated pressure equalization in the lid closure prevents excessive internal pressure buildup, which is particularly important during temperature fluctuations or when mounting devices that emit heat. The transparent cover allows visual inspection of installed components without opening the housing.

Compatibility and Accessories

The CI44E-250 can be extended with various accessories specifically developed for the CI44 series. These include mounting plates such as M-CI44 or MM-CI44, enabling secure fixation of devices inside. Adapters like SL630-ADP-CI or rail connectors such as SVS250630-5 support integration of busbars and other distributor elements. Lid hinges (DSCH-CI), lid closures (DV125-CI, DV150-250-CI), and cable ties (KS4-CI) enhance mounting and securing options. Perforated plates (L1-CI44, L3-CI43, L5-CI43) and busbar inserts (SE-RS-I44) offer additional flexibility in component arrangement. Touch protection covers GA-1-I44 and GA-RS-I44 increase safety during operation.

Mounting and Installation

Wall mounting is achieved using the integrated mounting brackets on the rear of the housing. The installation depth is 250 mm when using a mounting plate. The pre-punched openings on all sides facilitate cable routing, with the exact dimensions of the openings (e.g., M50/32, M63/40) enabling selection of appropriate cable entry plates or seals. The hinged side panels can be removed or opened as needed to convert the housing into an open distributor.

Operational Advantages

The combination of high mechanical strength, moisture protection, and flexible mounting design makes the CI44E-250 a robust and versatile housing for demanding installation situations. The sealable closures and transparent cover support maintenance and monitoring. The modular expandability through accessories allows customized adaptation to specific requirements in electrical and distributor construction.
