Technical Parameters Parameter Category Specification Product Series System Pro M - GS Rotary Switch-Disconnector Device Type Manual Rotary Switch-Disconnector (Isolator) Standard Compliance IEC/EN 60947-3, IEC/EN 60947-1 Rated Operational Voltage (Ue) 690 V AC Rated Insulation Voltage (Ui) 800 V AC Rated Impulse Withstand Voltage (Uimp) 8 kV Rated Frequency 50/60 Hz Rated Current (Ith / Ie) Up to 125 A (Depending on the specific model/pole version and enclosure). Common frame sizes: 32A, 63A, 125A. Utilization Category AC-23A (For switching of squirrel-cage motors with inrush currents up to 8 x Ie). Also suitable for AC-20, AC-21, AC-22. Short-Circuit Performance • Rated Conditional Short-Circuit Current (Icq) Typically 10 kA (When backed by appropriate upstream fuses, e.g., gG/gL type). • Rated Making Capacity (Icm) Up to 12.5 kA (peak, depends on version). Mechanical & Electrical Life • Mechanical Durability ≥ 20,000 operations. • Electrical Durability ≥ 5,000 operations at full rated load (AC-23A). Number of Poles Available in: 1-pole (1P), 2-pole (2P), 3-pole (3P), and 4-pole (4P) versions. Switching Position Clearly marked ON (I) and OFF (O) positions. Padlockable in the OFF position with up to 3 padlocks (standard) for safety lockout/tagout (LOTO). Connection & Terminals Screw-clamp terminals suitable for both copper and aluminum cables (with appropriate treatment). Mounting Can be mounted on a standard 35 mm DIN Rail (EN 60715) or directly on a panel. Actuation Rotary handle operation. Handle can be mounted on the device (direct) or remotely via an extension kit. Enclosure Material High-strength, self-extinguishing thermoplastic (Polyamide PA 6.6). Protection Rating (with enclosure) Up to IP65 (when properly installed with enclosure and gasket), providing protection against dust and water jets. Front panel typically IP40.
