ABB AC contactor

There are two wiring ways for users to choose, one two terminals at the same end of the product, the other two terminals at both ends of the product, the wiring is flexible and convenient. The base is made of glass fiber reinforced plastic with high strength and good dielectric performance. The installation method can be installed with screws, but it can also be installed with the guide rail, convenient disassembly and rapid. Conductive parts are not exposed, with good safety performance. A16-30-10AC220V Normal working conditions and installation conditions 1. The altitude of the installation site shall not exceed 2000M2, the surrounding air temperature shall not exceed + 40 degrees, and the average temperature value within 25H shall not exceed =35 degrees, and the lower limit of the surrounding air temperature is-5 degrees.3. The relative temperature of the air in the installation site is not more than 50% at + 40 degrees, and a higher relative temperature can be allowed at a lower temperature, such as 90% at 20 degrees, which is occasionally produced due to temperature changes.

A-series contactors have been widely used in all walks of life and are recognized by users. Especially in the wind power generation, solar power generation, electric locomotive and other fields have been widely used. The cause of the weak contact of the contact will increase the contact resistance, leading to the high temperature of the contact surface, making the surface contact into a point contact, or even the non-conduction phenomenon. The causes of this fault are: (1) there are oil, hair, foreign matter on the contact.(2) Long-term use, the contact surface oxidation.(3) Arc ablation causes defects, burrs or metal debris particles, etc.(4) The movement part has stuck phenomenon. Compact structure, with the characteristics of small volume, strong current carrying capacity, reliable work, cabinet space saving, suitable for the control of 4~5.5kW motor is especially suitable for the electric valve, automatic door, central air conditioning terminal, conveyor belt, compressor, water pump, electricity.
