Functions
Three operating positions: 1 (first source) – 0 (off) – 2 (second source).
Ensures safe switching between two power supply sources or two circuits.
Suitable for both load switching and circuit isolation.
Can be used as a manual ATS (Automatic Transfer Switch) substitute in smaller systems.
Mechanical construction designed for heavy loads and long-term use.

Applications
Industry: switching power supply sources for factories, workshops, warehouses.
Commercial buildings: connecting a backup generator when the main supply fails.
Energy sector: in substations and electrical cabinets as switching and isolation equipment.
Households (high-power systems): when manual switching between grid and generator is required.

Advantages
High current capacity – 630 A allows control of even very powerful circuits.
Robust design – durable mechanics (up to 10,000 cycles).
Certified quality – complies with IEC standards and ISO quality requirements.
Wide connection options – suitable for both cables and copper busbars.
High short-circuit current resistance – up to 20 kA peak current.

Disadvantages
Manual operation – no automatic transfer function.
Relatively heavy – may require additional support during installation.
Not suitable for low-power systems – due to high rated current, it may be oversized and costly for such systems.
