Switch-disconnectors are fundamental components in any electrical installation, designed to provide a visible and safe isolation point for circuits under load. Our range, primarily from the Eaton Moeller DUMECO series, includes models like the DMV, DMS, and the fused switch-disconnectors of the QSA series. These devices are engineered for robustness, offering high resistance to short-circuit currents. They are typically available in 3-pole (3P) and 4-pole (4P) configurations, with rated operational voltages up to 690 VAC. The DMV series covers a current range from 160A to 1600A, while the DMS series handles higher currents from 2500A to 3150A. The QSA fused switch-disconnectors are designed for ratings from 40A to 800A, providing integrated fuse protection. All units comply with EN/IEC 60947-3 and are certified by Lloyd's, Veritas, and CSA, ensuring global acceptance for industrial use.
These switch-disconnectors are primarily deployed in industrial power distribution panels, main switchboards, and motor control centers (MCCs). They are ideal for applications requiring a safe means of isolating machinery, transformers, or capacitor banks for maintenance. Their AC-23 utilization category makes them suitable for switching highly inductive loads, such as motors, as well as resistive loads like heaters. You will find them in sectors like water treatment, mining, cement plants, and large commercial buildings where reliable isolation and safety are paramount.
The main subcategories within this family are the DMV, DMS, and QSA series. The DMV series (e.g., DMV-160, DMV-250, DMV-630, DMV-1600) are compact switch-disconnectors for distribution. The DMS series (e.g., DMS-2500, DMS-3150) are heavy-duty switches for main incomers. The QSA series (e.g., QSA-40, QSA-63, QSA-100, QSA-200, QSA-400, QSA-800) are fused switch-disconnectors. The part number typically follows a pattern like 'DMV-160N3P' or 'QSA-200N3P', where the number indicates the rated current and the suffix denotes the number of poles and any special features.
