FAQs
Begin by verifying the panel’s available depth (22.5 in) and width (18.45 in) to ensure a proper fit. Mount the unit in a suitable enclosure with clear access to the pistol handle, then connect the three-phase conductors to the termination points. Check alignment with the CF fuse arrangement and secure the enclosure per the manufacturer’s torque specs. This approach minimizes wiring rework and keeps maintenance downtime short.
The data shows 600 V and 200 A in the product description, with an associated three-pole configuration for three-phase systems. The spec sheet also lists an Amperage Rating of 100 A in the formal spec block, indicating a potential variant difference. To confirm the exact rating for your order, refer to the Eaton datasheet for the specific catalog variant and intended application before integration.
Yes. The product is described with a NEMA 3R enclosure and CE marking, indicating suitability for weather-protected and damp environments typical of outdoor installations and sheltered indoor spaces. For harsh, direct exposure applications, verify the exact enclosure rating in the datasheet and ensure installation follows local electrical codes and the manufacturer's guidelines.
The ER3R-200CF3PR carries CE marking and utilizes a NEMA-rated enclosure (3R per the product description). These certifications support EU regulatory compliance and suitable protection against environmental factors in industrial settings, facilitating safe operation, audits, and cross-border deployments.
The integrated CF fuse option and pistol-handle design streamline maintenance, reducing the number of separate components and training required for safe operation. By providing a clear isolation point and robust enclosure, it helps minimize downtime during servicing, improve safety, and support longer equipment life, contributing to a favorable total cost of ownership in manufacturing and process environments.
