This product is created in accordance with the company's ongoing strategy to develop high-quality products. Excellent appearance, advanced drive design and reliable insulation characteristics have ensured this model constant recognition from users.
Mechanism
1. Optimized design layout ensures ergonomic operation and excellent performance.
2. The use of surface treatment methods, including electrostatic powder coating of the case and galvanic nickel-phosphorus coating of up to 80% of the mechanism parts, guarantees both an attractive appearance and high internal quality.
3. The use of a two-stage switching device can significantly reduce the actuation force of the switching release and increase the reliability of switching.
4. The use of two-stage gear reduction in the energy storage mechanism ensures smooth operation and compact design.
Main circuit
1. Adopts solid insulation design; Advanced monolithic epoxy casting technology seamlessly integrates the vacuum arc chute, current-carrying circuits and insulating supports into a single monolithic column (pole). This made it possible to fundamentally solve the problem of the resistance of the vacuum circuit breaker to the external environment, expand the scope of its application, and also provide the possibility of miniaturizing the product.
2. The use of unique R-shaped contacts ensures excellent switching performance when switching capacitive loads (capacitor banks).
3. The special soft shell technology of the vacuum arc chute further improves the insulating properties of the monolithic pole.
