1. It can be used for three-phase neutral ground or neutral point ungrounded AC system;
2. The circuit breaker adopts a three-pole porcelain pillar structure, the three poles are equipped with a spring operating mechanism, centered arrangement, and the three poles are connected;
3. The self-energy arc extinguishing principle is adopted, and the optimized design is carried out in the circuit breaker motion system, which effectively improves the mechanical efficiency and minimizes the operation work;
4. SF6 density controller (with pressure gauge) monitors the density of SF6 gas in the circuit breaker and sends a control signal, with temperature compensation function. When the ambient temperature changes and the SF6 gas pressure changes, the controller indicates the same value. Only when SF6 gas leakage causes a change in gas density, the controller will issue an alarm and lock signal;
5. The spring operating mechanism is equipped with strong breaking ability, small operation power and high reliability. The control cabinet is connected to the base through 6 M20 bolts, and there are moisture-proof and waterproof devices at the connection between the output shaft of the mechanism and the B-phase arm and at the exit of the secondary line;
6. On the inner panel of the control cabinet, there are manual opening and closing buttons, remote to local transfer switches, energy storage motor switch circuit breaker status signs;
7. Suitable for high altitude environment (2500m).
