abb circuit breakers

Compared with the DC arc, the AC arc has a process of current zero-crossing, and the arc will be extinguished automatically. We only need to take measures to prevent the arc from reburning after the zero-crossing. The DC arc does not have a zero-crossing process, so the DC arc is difficult to extinguish. 

Productivity is greatly improved, while design and installation are greatly simplified at all stages of the product life cycle, from design to day-to-day operations. Save 15% on terminal connection and installation time. Alarm tracking and grid analysis functions ensure work continuity.

Tmax is ABB's molded case circuit breaker with a current of up to 630A. It exhibits excellent performance in a smaller size than similar products on the market. It can be flexibly equipped with electronic or thermal-magnetic trippers to meet various protection function requirements.

The structure of the circuit breaker is made of steel plate, which can reduce the size of the circuit breaker and make it more compact. Double-layer insulation is used to isolate the charged body to enhance its safety, and the phases are completely separated.

ACS510 drives are used in industrial fields and are suitable for various types of loads. ACS510 is also specially optimized for fan and water pump applications. Typical applications include constant pressure water supply, cooling fans, subway and tunnel fans, etc.

Casting pole features: The use of vacuum disconnection technology can prevent the contacts in the vacuum environment from being oxidized and polluted, and at the same time, the vacuum interrupter can be reliably protected and prevented from mechanical impact, dust, moisture and other potential accidents.

First of all, the structure and dimensions of the circuit breaker and the existing system can be completely matched with each other, which can ensure the coordination and continuity of the appearance. The accessories of ABB miniature circuit breakers are relatively complete, allowing three auxiliary contacts to be installed at the same time.
