Eaton Specification Sheet - ER4X-800L3PR
The ER4X-800L3PR employs an enclosed rotary disconnect switch with fuse type L and a pistol-style handle, delivering safe one-handed operation and arc flash mitigation during isolation. This design reduces maintenance risk and supports compliant lockout-tagout procedures, improving overall safety in control panels and motor control centers. Its high-current capability—800 A at 600 V—allows large motors and feeders to be served from a single device, simplifying wiring, reducing component count, and improving reliability on conveyors, machine tools, and process lines. The NEMA 4X enclosure provides robust protection against dust, water, and corrosion, enabling uptime in wash-down areas, outdoor installations, and other harsh environments. CE marking ensures European conformity, easing global procurement and regulatory compliance for multinational projects. A compact footprint and lightweight profile facilitate retrofits in space-constrained panels, while compatibility with Bussmann series components supports easy spares and maintenance planning. The pistol handle and rugged mechanical design contribute to safer, faster installs and long-term serviceability for OEMs and integrators.
