Reinforced PET construction provides rugged durability against impact and chemical exposure while keeping weight manageable for quick site handling. This material choice translates to lower enclosure damage costs and easier transport during panel builds. Ideal for control panels and conduit terminations in factory floors and outdoor equipment. IP66 ingress protection safeguards connections from dust and powerful water jets, minimizing downtime and maintenance needs in washdown zones and dusty plants. The seal integrity supports longer service intervals and safer electrical terminations in challenging environments. Use this enclosure on machinery, conveyors, and outdoor enclosures where reliability matters. Surface mounting simplifies installation with fewer brackets and faster panel integration. This reduces labor time during commissioning and simplifies field upgrades for existing systems. It is well-suited for control panels, junctions, and instrument enclosures in tight or cluttered electrical rooms. Compact dimensions (4.63 in depth, height; 2 in width) and a modest 2.5 lb weight help fit into crowded panels and equipment enclosures. Predictable sizing supports efficient panel planning, cable routing, and inventory management for projects of any scale. This makes JUSN42B a versatile upgrade for existing Pauluhn JUSN installations. Designed to integrate with Eaton's Pauluhn JUSN series, the JUSN42B delivers compatibility with standard conduit and mounting patterns. This reduces rework and ensures a consistent enclosure ecosystem across installations.

FAQs
The JUSN42B is designed for surface mounting, offering a straightforward installation path with a single enclosure footprint. This reduces brackets, fasteners, and complexity during panel builds while ensuring a secure, weatherproof seal in ordinary locations. For best results, follow the included installation instructions and verify that mounting hardware matches the surface substrate and conduit layout of the application.
JUSN42B provides IP66 ingress protection, guarding against dust ingress and powerful water jets. The enclosure is manufactured from reinforced polyethylene terephthalate (PET), delivering impact resistance and chemical stability suitable for industrial environments. This combination supports longer service life and lower maintenance costs in challenging conditions.
Yes, the JUSN42B is part of Eaton’s Pauluhn JUSN family, offering compatibility with standard conduit outlets, mounting patterns, and accessories in the series. This consistency simplifies upgrades, panel redesigns, and lifecycle maintenance by preserving common dimensions and connection interfaces across the enclosure ecosystem.
JUSN42B is specified for ordinary/non-hazardous locations, making it suitable for factory floors, general industrial control panels, and non-hazardous process areas. Its IP66 protection ensures resilience in dusty or wet environments, while PET construction supports durability and corrosion resistance in typical plant settings.
The combination of IP66 sealing, PET material, and a compact surface-mount design minimizes ingress-related failures and simplifies installation. Fewer components and faster assembly reduce labor time during commissioning, while robust material choice lowers replacement and repair costs over the product life cycle, contributing to a lower total cost of ownership for control panels and conduit installations.
