Parameters: Parameter Value / Description Product Series Harmony WATSNA (Watertight Switch, High Current) Rated Operational Current (Ie) 63 A Utilization Category AC-22A / AC-23A (For switching of mixed resistive and inductive loads, including motor loads up to its rating). Capable of making and breaking current under load. Number of Poles (Main) 4 (L1, L2, L3, N) Auxiliary Contacts Likely 4 (As suggested by /4 in the model, used for remote position signaling). Exact configuration (e.g., 2NO+2NC) to be confirmed by catalog. Rated Operational Voltage (Ue) Up to 690 V AC Rated Insulation Voltage (Ui) 690 V Protection Rating (IP) IP65 (Dust-tight and protected against water jets) when properly closed. IP66 is typically an option. Enclosure Material Polycarbonate (PC) or Stainless Steel (SS) – High impact, corrosion and UV resistance. Mounting Surface mounting. Actuation Manual rotary handle operation. Handle is usually removable for locking in the OFF position (up to 3 padlocks). Position Indication Clear "O" (OFF/Open) and "I" (ON/Closed) markings, with a visible contact position indicator. Mechanical Life High (e.g., ≥ 50,000 operations) Electrical Life Depends on load (e.g., ≥ 10,000 operations at rated current). Standards IEC/EN 60947-1 and IEC/EN 60947-3 (for switch-disconnectors) Ambient Temperature Typically -25°C to +60°C
