Mã sản phẩm: DW10M-630A 400A

DW10M series circuit breaker is suitable for AC 50HZ, voltage to 380V, DC voltage to 440V electrical circuit for overload, short circuit, voltage loss protection and infrequent conversion under normal conditions. When a three-pole circuit breaker is used in series in a DC circuit, the voltage is allowed to increase to 440V.

Second normally open and normally closed, DC 220V
Main features: 1. The snap-on contact structure is installed on the same rotating insulating square shaft, and the action is synchronized; the different capacity contacts and arc chamber can be combined into different current level and voltage level circuit breakers. It can meet the requirements of degaussing of domestic and foreign medium and small capacity generator sets, and the special requirements of ZnO non-linear resistance demagnetization for arc voltage. Compared with domestic and foreign similar products, it has advanced performance, simple structure and reliable operation. Ingenious. 2. The unique transmission mechanism of electromagnetic closing, permanent magnet holding and anti-magnetic opening brake replaces the traditional mechanical locking device and requires no maintenance, which greatly improves the protection reliability and service life of the circuit breaker. 3. The magnetic field replaces the normal series arc-blowing system and the arc-extinguishing chamber made by the short-arc principle, which not only ensures reliable breaking under small current, but also establishes constant arc voltage, thus ensuring reliable circuit breaker breaking. The converter is de-excited.
