Eaton Crouse-Hinds 2722A Toggle Switch - 277 Vac

Copper-free aluminum construction reduces weight and enhances corrosion resistance, helping extend switch life in busy control panels. By eliminating copper, the 2722A minimizes galvanic concerns and simplifies sourcing of compatible parts. This material choice also enables slimmer profiles that fit crowded enclosures without sacrificing strength. The result is lower maintenance costs and longer replacement intervals for critical indexing and signaling circuits. The switch’s exterior dimensions are designed for predictable mounting in standardized Pauluhn enclosures, reducing design risk for OEM configurations. This consistency also simplifies cable routing and spare parts planning across multiple projects. With a 20 A amperage rating and 277 Vac voltage rating, the 2722A reliably handles typical control loads in industrial panels. The single-pole, surface-mount design streamlines wiring, reduces enclosure depth, and enables faster field installations. Being part of the Pauluhn 27S family, it benefits from a long-standing catalog of compatible accessories and standardized mounting footprints. The rugged copper-free body resists wear from repeated actuation, supporting millions of cycles under normal plant duty. Design engineers will appreciate the consistent actuation force and tactile feedback, aiding operator acceptance. The unit’s weight and balance also facilitate safer, easier panel changes during maintenance. Installation aligns with common panel design practices, leveraging existing cutouts and mounting hardware to minimize additional parts. Compatibility with Eaton’s catalog pages and installation instructions helps ensure first-pass success during commissioning. Operators appreciate the reduced risk of mis-wiring thanks to clearly labeled terminals and robust mechanical interlock. Redundant sealing features and precise tolerances help maintain switch performance in environments with vibration. Area classification indicates Ordinary/Non-Hazardous Locations, which guides safe deployment in general machinery and non-explosion-proof environments. This clarity supports procurement and compliance teams in fast-tracking approvals. The combined specification of copper-free aluminum and surface mounting contributes to cost-effective panel strategies for high-mix, low-volume manufacturing. Industry deployments across automation, packaging, and material handling highlight tangible ROI from longer service life and reduced downtime during scheduled maintenance. The copper-free aluminum construction, 20 A/277 Vac rating, and surface-mount design make the 2722A a pragmatic choice for scalable control panels. End users report lower maintenance costs and faster changeouts when upgrading from older, heavier toggle switches. Availability of Pauluhn interior catalog pages and installation sheets accelerates design-in and commissioning across multiple sites.
