Eaton Specification Sheet - ER12-30N3PR
Enclosed rotary disconnect design provides reliable single-point isolation; the non-fused construction reduces spare parts需求 and simplifies maintenance routines, lowering lifecycle costs while ensuring operator safety in control panels and power distribution applications. The 600 V / 30 A rating supports consistent performance under typical industrial loads, enabling scalable automation without frequent hardware upgrades. A NEMA 12 enclosure rating protects internal components from dust and light splashes, reducing contamination risk in dry to mildly wet environments such as manufacturing lines and assembly areas. CE marking ensures global regulatory alignment, accelerating project approvals and reducing compliance gaps across multi-market deployments. The compact form factor and pistol-style handle enable ergonomic operation and space-efficient installations in dense panels, improving installation speed and reducing downtime. The non-fused design simplifies fuse management and spare-part planning, delivering lower maintenance overhead and easier integration with existing Eaton Bussmann series products.
