> 可上下进线：断路器的主电路无需区别电源侧和负载侧，上、下进线均都适用，其分断能力指标相同。
>SYTW3 series intelligent universal circuit breaker has the following characteristics:
A, SYTW3 series of intelligent universal circuit breakers are available in fixed, drawer and three-pole, four-pole varieties.
Rated current 200, 400, 630, 800, 1000, 1250, 1600, 2000, 2500, 2900, 3200, 3600, 4000, 5000, 6300A and other specifications, all kinds of
accessories are complete;
B. The circuit breaker has a high rated short-time withstand current and breaking capacity.
The MCR and analog trip function are used to increase the limit breaking capacity.
C, the contact system of the circuit breaker
Each phase contact is installed in an insulated chamber, and the contact system adopts a multi-parallel structure with one-speed contacts and
has main contacts and arc contacts.
The function of the electric repulsion is improved at the same time, the electric stability of the contact system is improved, and the high breaking
capacity of the circuit breaker is ensured.
>Operating mechanism: The operating mechanism of the circuit breaker is installed in the center of the circuit breaker and is isolated from the
main circuit. The circuit breaker is closed by the spring energy storage mechanism, and the closing speed is fast.
>The circuit breaker has a long service life: it can be connected and the number of breaking operations can reach 10,000 to 20,000 times.
>No additional arcing distance: The arc-extinguishing hood is installed above the circuit breaker, and the de-ioning grid is used to double-
extinguish the arc. The arc-extinguishing effect is good, and the arcing distance above the circuit breaker is “zero”.
> Up and down access: The main circuit of the circuit breaker does not need to distinguish between the power supply side and the load side.
Both the upper and lower incoming lines are applicable, and the breaking capacity indicators are the same.
