Quick Summary
Rotary switch enables reliable circuit selection for control panels in industrial equipment. In harsh environments, ingress and moisture can drive downtime and maintenance costs. This model features IP66 protection and Ordinary/Non-Hazardous Locations area classification to deliver dependable performance in exposed enclosures; its surface-mount design simplifies wiring and reduces panel depth. Ideal for Pauluhn 862/1869/1871 series installations, it supports 1/2" trade-size connections and fast, code-compliant mounting. Engineers benefit from predictable operation across both 120 Vac and 240 Vac supplies, with 20 A current capability and 1 HP at 120 V or 2 HP at 240 V. From a procurement perspective, the brass body and surface-mount format support long service life and easier replacement in retrofit projects.

IP66 ingress protection and brass construction shield the Pauluhn 862/1869/1871 rotary switch from dust, water, and washdown environments, extending service intervals and reducing maintenance costs. This protection translates into higher equipment uptime in outdoor control panels and marine applications, where exposure to rain and spray is common. The combination of weatherproofing and robust materials makes it a practical choice for panel builders seeking reliable industrial control solutions. With a 20A amperage rating and horsepower capability of 1 HP at 120 V and 2 HP at 240 V, the 1871B-C1 handles common motor and control circuit loads without additional relays, reducing installation complexity and potential failure points for conveyors, fans, and small pumps. Through-feed entry simplifies wiring—pull conductors through the switch box, reducing field modifications during installation and improving retrofit timelines. The square, surface-mount footprint fits standard enclosure cutouts while minimizing panel depth, supporting neater cable routing and faster commissioning. The brass construction offers corrosion resistance for ordinary locations, enabling longer service life and easier maintenance in environments with moisture exposure. Compatibility with Pauluhn 862/1869/1871 series hardware ensures seamless replacement and consistent operation within existing control stations, simplifying procurement and service planning for maintenance teams.

FAQs
Installation begins with confirming a 1/2" trade-size opening and an appropriate surface-mount footprint. Use through-feed entries to route conductors into the box, then secure the switch to the panel with the provided mounting hardware. Ensure the enclosure supports IP66 protection and non-hazardous locations. Wire the 120/240 Vac supply to the designated terminals and verify continuity with a multimeter before commissioning.
Yes. The switch is rated for 20A with 1 HP at 120 V and 2 HP at 240 V, making it suitable for typical small motors and control circuits in industrial panels. For higher horsepower applications, consider staging or relays while using the switch as the control selector.
This model excels in Pauluhn series installations within ordinary/non-hazardous locations. Common uses include outdoor control panels, marine equipment, conveyors, fans, and pump circuits where IP66 protection and reliable switching are required to minimize downtime and maintenance.
Key certifications include IP66 ingress protection and Ordinary/Non-Hazardous Locations classification. The unit is designed for surface mounting, through-feed wiring, and operates on 120/240 Vac with a 20A rating, supporting code-compliant installations in non-hazardous environments.
Benefits include longer service life from brass construction and weatherproof IP66 protection, reduced wiring labor due to through-feed entries, and fewer relays needed thanks to the 20A, 1/2" switch capability. Over time, these factors translate to lower maintenance costs, quicker repairs, and improved uptime for critical panel applications.
