SF6 gas-insulated circuit breaker LW10B-550

overcurrentmodular

The LW10B-550 circuit breaker uses SF6 gas as the insulating and arc-extinguishing medium. Its extinguishing chamber is a single-voltage variable opening distance. The circuit breaker is equipped with a spring energy storage hydraulic mechanism for opening, closing, and automatic reclosing to match rated current and fault current, switch circuits, and achieve control and protection of transmission lines. It has a strong breaking capability of 63kA, accumulates 20 short-circuit breaks, and can achieve phase selection switching and closing control, with high control accuracy and a mechanical lifespan of up to 10,000 cycles.
