FAQs
Installation follows standard non-fused disconnect practices: verify panel ratings exceed 600 V and 16 A, mount the compact unit to a suitable enclosure surface, connect power and control conductors per schematic, and enable lockout/tagout with the pistol handle. The unit’s rugged enclosure supports secure mounting in tight panels while maintaining accessibility for maintenance.
The ER4X-16N3PR features a 16 A amperage rating, 600 V voltage rating, and a NEMA 4X enclosure. It is non-fused and CE marked, making it suitable for many industrial applications requiring reliable circuit isolation while meeting common European and global safety standards.
Yes. The NEMA 4X enclosure rating provides protection against dust, moisture, and washdown conditions, making it appropriate for outdoor installations, wet processing environments, and equipment exposed to cleaning workflows while preserving electrical isolation integrity.
The unit is CE Marked and uses a NEMA 4X rated enclosure, aligning with European conformity requirements and rugged industrial usage. While UL or other certifications are not listed in the data, CE compliance and enclosure protection are key signals of reliability for international projects and regulated environments.
The non-fused design simplifies maintenance by reducing fuse-related replacements and potential failure points. Its pistol handle supports fast, lockable operation, which minimizes downtime during maintenance. Over the lifecycle, customers typically see lower spare-part costs and improved uptime in automated lines and control panels.
