Eaton Crouse-Hinds 841B-277 Receptacle - IP66 Rating

IP66 ingress protection is a defining feature for the 841B-277, guarding against water jets and dust intrusion. This translates to lower field failure rates and reduced maintenance costs in outdoor enclosures, washdown areas, and damp plant spaces. Use this receptacle in Pauluhn 800 interlock assemblies or similar lockable configurations where enclosure integrity matters. With a 20A amperage rating at 277 Vac, the 841B-277 supports typical plant loads without overdesign. The business impact is predictable start-up behavior and improved circuit protection for motor controls and control panels, reducing nuisance trips. It's compatible with standard industrial distribution components, simplifying integration into existing 277 Vac networks. Brass construction provides robust corrosion resistance in humid and chemical environments, extending service life in demanding facilities. This material choice also supports more durable mating contacts under repeated interlock actions, lowering replacement frequency and downtime. Pair with Pauluhn interlock components for reliable safety interlock performance in process lines. Three-wire, two-pole configuration ensures proper grounding and safer fault isolation in control circuits. The design supports safer maintenance and compliance with typical plant grounding practices, improving installer confidence. It also aligns with common wiring device standards used across automotive, food & beverage, and general manufacturing environments. Compact dimensions (5.19 in depth, 7.5 in height, 4.5 in width) and a 9.2 lb weight provide a stable, enclosure-friendly footprint. The catalog number 841B-277 and UPC 662276387515 support traceability and warranty claims, while the brass/reinforced housing contributes to long-term reliability. These features collectively reduce installation risk and accelerate field deployment in new builds or retrofit projects.
