Eaton ER4P-800L3PR Enclosed Rotary Disconnect Switch - NEMA 4P

NEMA 4P enclosure provides rugged protection against dust, dirt, and water ingress, enabling outdoor and wash-down applications with reduced maintenance cycles and longer service life. This translates to lower downtime and a stronger return on investment when deployed in outdoor substations, MCCs, and harsh industrial environments. The 600 V, 800 A electrical rating supports high-current isolation in main disconnects, consolidating equipment footprints and reducing the need for multiple components in motor control centers. By integrating fuse type L within the switch, customers gain selective coordination and safer fault isolation, minimizing arc flash exposure during maintenance and enabling faster service windows. The pistol-style handle offers ergonomic operation and safer manual manipulation, which translates to improved operator safety and compliance with internal lockout/tagout procedures. CE marking and NEMA 4P enclosure together ensure regulatory alignment and environmental resilience across global sites, simplifying procurement and installation in European and North American facilities. The compact 12 in depth, 12.25 in height, and 7.5 in width footprint fits standard enclosures, aiding panel designers and installers while keeping weight manageable at 11.24 lb for easier handling. This model’s integration with Bussmann series protections supports streamlined spares and consistent performance across installations, reducing lifecycle costs and inventory complexity.
