Features
- 4-Pole Configuration: Simultaneously switches 3 phases and the Neutral line, ensuring total isolation and safety for 3-phase 4-membered systems.
- Mechanical Interlock: A built-in physical barrier prevents the handle from engaging both power sources at once, eliminating the risk of back-feeding and short circuits.
- Three Stable Positions (I-O-II): * Position I: Connects to Source 1 (Grid).
- Middle Position (O): Disconnects all loads (Safety/Maintenance mode).
- Position II: Connects to Source 2 (Generator/Solar).
- High Breaking Capacity: Rated to handle up to 63A continuous current with high short-circuit making capacity for industrial-grade protection.
- Flame Retardant Material: Constructed with high-quality, heat-resistant PA66 plastic for maximum durability in harsh environments.
- Easy Installation: Standard 35mm DIN rail mounting makes it compatible with most modern electrical panels and MCB boxes.
