FAQs
Installation considerations include ensuring a compatible panel cutout and mounting pattern, verifying the 600 V and 16 A ratings meet your feeder current, and maintaining proper clearance for safe operation. The ER4X-16N6SR’s compact footprint and standard Eaton Bussmann mounting simplify retrofit projects, while its non-fused selector design minimizes wiring complexity and stock requirements. Use lockout/tagout procedures during installation to maximize safety.
Electrical performance for ER4X-16N6SR centers on 600 V nominal voltage, 16 A continuous current, and a NEMA 4X-rated enclosure. This combination supports reliable isolation in harsh environments while meeting CE compliance. It is non-fused and acts as a selector, enabling simple, deliberate operation in control panels, motor starters, and switchgear. For critical applications, verify wire sizing, insulation coordination, and available accessories to ensure full-system compatibility.
Yes. The NEMA 4X enclosure provides resistance to dust, water ingress, and washdown environments, making ER4X-16N6SR suitable for outdoor enclosures, damp locations, and harsh industrial settings. The 600 V/16 A rating supports feeders in control panels and motor circuits, while CE marking confirms regulatory alignment. For outdoor install, ensure protection against direct weather exposure and follow proper mounting to maintain performance.
ER4X-16N6SR integrates with Eaton Bussmann protection schemes by using a compatible non-fused selector in standard mounting patterns, simplifying wiring and sequence control. It supports safe lockout, easy integration with fusing and protective devices, and reduces commissioning time in new builds and retrofits. Ensure compatible control wiring, interlocks, and panel schematics to maximize protective coordination and minimize downtime.
From a maintenance and ROI perspective, ER4X-16N6SR reduces downtime by eliminating fuse handling and enabling straightforward manual isolation. Its robust, corrosion-resistant enclosure and simple replacement path lower lifecycle costs, while CE and NEMA 4X compliance reduce risk of regulatory nonconformance. For manufacturers, this translates to safer operations, faster turnarounds, and predictable maintenance planning.
