FAQs
The ER4-16N6SR is designed for enclosed panel mounting, matching standard Bussmann/Eaton industry installations. It supports typical control panel layouts, enabling straightforward retrofits in space-constrained cabinets. When planning installation, verify compatible mounting rails or enclosures, reference the product drawings, and align the switch with existing wiring harnesses to minimize rework and ensure reliable isolation status indicators.
Yes. The ER4-16N6SR features a NEMA 4 enclosure, delivering weather resistance and dust-tight protection suitable for outdoor installations, damp environments, or wash-down areas. For best results, install in accordance with enclosure instructions and ensure proper sealing around mounting points to maintain the protective rating and long-term reliability.
ER4-16N6SR is a non-fused, selector-type disconnect with a 600 V voltage rating and 16 A current rating. This combination supports common industrial control circuits, enabling safe isolation for typical motor control centers, conveyors, and machine tools while facilitating quick, reliable shutdown procedures in production lines.
Begin with de-energizing power and consulting the Eaton wiring diagrams. Identify the line and load terminals, use appropriate gauge conductors, and follow standard wiring practices for non-fused disconnects. Ensure the selector handle is clearly visible and the enclosure remains sealed after wiring. Test the isolation function and verify that the CE-marked device maintains its NEMA 4 rating under operating conditions.
The ER4-16N6SR reduces fuse handling and spare part requirements thanks to its non-fused design, cutting maintenance time during shutdowns and replacements. Its robust NEMA 4 enclosure and CE compliance support longer service life in challenging environments, lowering downtime and improving overall equipment effectiveness (OEE) in automated lines without sacrificing safety or performance.
