FAQs
The ER3R-16N3PB is designed with a NEMA 3R weatherproof enclosure and a pistol-style handle for safe, one-handed operation. It should be mounted in a compliant enclosure or panel that matches its 600 V/16 A rating, with proper grounding and wiring practices. Ensure clear labeling and access to the disconnect for servicing and testing.
This model provides a non-fused isolation solution rated for 600 V and 16 A, suitable for many industrial control circuits. The non-fused design reduces fuse coordination complexity, while the NEMA 3R enclosure supports outdoor or damp environments. These specs enable reliable isolation without additional protective devices inside the disconnect unit.
Yes, the ER3R-16N3PB is CE marked, indicating compliance with applicable European health, safety, and environmental requirements. The product also features a NEMA 3R enclosure rating, supporting outdoor and moisture-prone environments. These certifications help ensure regulatory alignment for global deployments and panel builder approvals.
Best suited for outdoor electrical panels, machine isolation points, and process lines where robust, non-fused isolation is required. Its 600 V/16 A rating fits common control circuits, and the weatherproof enclosure makes it suitable for exposed installations, outdoor substations, and equipment bays in manufacturing facilities.
Maintenance benefits include reduced part complexity due to the non-fused design, easier field servicing with a pistol handle, and straightforward replacement steps. Return on investment comes from lower downtime during switchovers, simplified spare parts inventory, and improved compliance, contributing to lower lifecycle costs in high-use automation environments.
