FAQs
Yes. ER3R-63N3PR is designed as an enclosed rotary disconnect switch that complements Eaton Bussmann series protection devices. It supports 63 A, 600 V circuits and uses a non-fused design, making it a straightforward fit for standard control panels, motor control centers, and protection assemblies in industrial environments.
Key specifications to verify are 63 A amperage rating, 600 V voltage rating, non-fused operation, and NEMA 3R enclosure. The CE marking confirms compliance with applicable European safety standards. Ensure wiring follows the device’s catalog and installation guidelines to achieve reliable isolation during maintenance.
This switch excels in manufacturing lines, packaging, and automated machinery where safe, frequent isolation is needed. Its NEMA 3R enclosure supports outdoor and damp environments, while the pistol handle enhances operator safety. It’s well-suited for service panels, outdoor equipment housings, and control stations requiring robust, non-fused disconnects.
ER3R-63N3PR carries CE marking and a NEMA 3R rating, indicating compliance with European safety requirements and suitability for protected outdoor use. These certifications support regulatory alignment in many facilities, facilitate supplier qualification, and help streamline purchasing for projects with stringent safety and environmental criteria.
Adopting a non-fused, enclosed disconnect reduces spare parts handling and fuse-related maintenance, leading to lower ongoing costs. The pistol handle improves operator efficiency during routine isolation, and the rugged NEMA 3R enclosure extends service intervals in harsh environments, delivering measurable uptime gains and a favorable return on investment.
