Eaton 1871B Rotary Switch - Surface Mount, 20A, IP66
Part Number: 1871B
Quick Summary
Eaton 1871B Rotary Switch is a rugged control device for marine and industrial control panels. Engineers often struggle with compact, weather-exposed switches that fit standard Pauluhn boxes and withstand harsh environments; this model addresses those integration challenges with a surface-mount, square brass design. Key certifications and compliance help streamline procurement and safety audits: IP66 protection for washdown resistance, Ordinary/Non-Hazardous Locations classification, and compatibility with Eaton Crouse-Hinds Pauluhn 862/1869/1871 family. Beyond robustness, the 1871B combines straightforward installation with predictable electrical performance—20A at 120V (1 HP) and 2 HP at 240V—reducing downtime and simplifying spare-part planning for maintenance teams.

Eaton Specification Sheet - 1871B
Feature → Business Impact → Application: Brass construction provides corrosion resistance in challenging environments, increasing switch life and reducing maintenance costs in marine and industrial panels. This durability translates to lower replacement frequency and predictable performance under washdown, improving overall OEE. Feature → IP66 ingress protection → Compliance assurance and safer operation in harsh settings; ideal for surface-mounted control stations in ordinary locations like dry docks or manufacturing floors. Feature → 120/240 VAC rating with 20A current capacity → Versatile control of motors and circuits up to 1 HP at 120 V or 2 HP at 240 V; accelerates panel design and reduces the need for multiple SKUs. Feature → Surface mounting with square brass form factor → Simplified installation and compact enclosure fitment, enabling quicker commissioning and easier retrofit in Pauluhn 862/1869/1871 assemblies. Feature → Catalog 1871B compatibility with Pauluhn series → Ensures seamless replacement, spare-part availability, and long-term support for legacy control schemes, reducing total cost of ownership. Industry insight: In harsh industrial and marine environments, selecting a durable, standard-form rotary switch like the 1871B minimizes lifecycle risks and unplanned outages while aligning with Eaton’s robust protection and control ecosystem.

FAQs
Yes. The 1871B is part of the Pauluhn 862/1869/1871 family and is specified for surface mounting in Pauluhn boxes. For installation guidance, refer to the IF LBL 1511 instruction sheet and the Pauluhn rotary switch catalog page, which outline mounting dimensions, box fit, and wiring considerations to ensure a secure, code-compliant installation.
The 1871B is rated for 20A at 120 VAC and 2 HP at 240 VAC, with a HP rating of 1 HP at 120 V and 2 HP at 240 V. It supports 120/240 VAC and uses a brass, square, surface-mount form factor, making it suitable for medium-duty control circuits in industrial and marine environments.
Best suited for ordinary/non-hazardous locations requiring rugged, surface-mount rotary control in control panels, particularly within marine or industrial facilities using Pauluhn assemblies. The IP66 rating ensures protection against dust and water exposure, supporting reliable operation in washdown zones and exposed panel locations.
The 1871B carries IP66 ingress protection and an Ordinary/Non-Hazardous Locations classification, aligning with standard industrial and marine safety requirements. These features simplify procurement and qualification processes for facilities needing reliable, compliant control switches in non-hazardous areas.
Brass construction and IP66 protection translate to extended switch life and reduced maintenance intervals, lowering total cost of ownership. Its compatibility with Pauluhn boxes and straightforward surface-mount installation shorten commissioning times and simplify spare parts planning, delivering faster recovery from outages and improved system availability.
