Three-pole enclosed rotary disconnect switches provide robust isolation for three-phase circuits, delivering direct safety improvements and enabling reliable service work in control panels, machine assemblies, and outdoor installations. This 600 V, 100 A rating supports common mid-range industrial loads, reducing the need for oversized equipment while maintaining safety margins and compliance during commissioning. The NEMA 14 enclosure adds dust, splash, and weather resistance, enabling outdoor or damp locations without compromising performance or maintenance downtime. Fuse type CF, CST integration offers precise upstream protection and selectivity, leading to fewer nuisance trips and streamlined spares management in production environments. The pistol-handle design enhances operator safety and ergonomics during frequent on/off cycles, supporting faster maintenance windows and reduced risk of manual misoperation. CE Marked compliance assures cross-border safety alignment, simplifying European and global deployments for panel builders and service teams. With a compact footprint and Eaton Bussmann fuse compatibility, this switch fits tight panel layouts while ensuring reliable performance and easy serviceability throughout the equipment lifecycle.

FAQs
Installation requires mounting the three-pole enclosed rotary disconnect in a compliant panel enclosure with room for a 21 inch depth and 15.74 inch width. Wire the line and load conductors to the appropriate terminals, ensure the CF/CST fuse option is selected for upstream protection, and operate with the pistol-style handle to verify mechanical engagement. Verify 600 V rating and 100 A capacity are within system specifications, and follow local electrical codes during commissioning.
The ER3R-200CF3PB-CST is rated for 600 V AC with a 100 A amperage rating and a three-pole configuration. It uses a NEMA 14 enclosure for environmental protection and includes CF/CST fuse-type options. The unit is CE Marked, indicating conformity with European safety standards, and is suitable for essential isolation in mid-range industrial applications.
Yes. The NEMA 14 enclosure rating provides protection against dust and water ingress, making it appropriate for outdoor installations or damp indoor environments. When combined with CE compliance and rugged pistol-handle operation, this switch supports reliable performance in harsh industrial settings while maintaining safety during routine maintenance and emergency shutdowns.
This model is CE Marked for European safety compliance and features a NEMA 14-rated enclosure for environmental protection. The three-pole design and fuse-type CF/CST options further support protective coordination in automated systems. While the data specifies CE Marking and NEMA 14, always verify additional regional requirements and any site-specific approval needs during procurement.
The enclosure’s rugged build, CF/CST fuse options, and pistol-handle operation reduce maintenance time by enabling quick, safe shutoffs and easier fuse replacement. The NEMA 14 protection minimizes weather-induced downtime, while CE compliance simplifies cross-border installation. Combined, these factors lower total cost of ownership by improving uptime, simplifying spares management, and accelerating service cycles in mid-size industrial lines.
