Eaton Specification Sheet - EP834
The EP834 delivers a 20A, 600 Vac rating with a two-pole configuration, enabling direct control of high-load equipment and reducing the need for external contactors. Its brass body paired with a spring-loaded single-throw mechanism minimizes wear and arcing, extending switch life in harsh environments. Applications include motor controllers, pumps, and conveyors in chemical plants and refineries where reliability matters. IP66 ingress protection and NEC/CEC compliance provide proven protection in dust, water, and explosive atmospheres, helping pass regulatory audits and lowering downtime. This also means safer maintenance windows for offshore platforms and mining operations. Surface-mount installation simplifies retrofits, minimizes cabinet space, and accelerates commissioning when used with Pauluhn EP83 enclosures, translating to shorter project timelines. Brass construction offers corrosion resistance for humid or chemically aggressive environments, supporting long service life in hazardous locations. Documentation and data sheets from Eaton facilitate fast engineering reviews and field testing, while cross-compatibility with EP83-series components streamlines procurement and maintenance planning.
