Product Description
This series of high voltage vacuum contactors is manufactured in a solid insulating frame using high quality vacuum arc chutes. The secondary control circuit is simple and reliable, and the operation is stable. A one-piece insulating casing is installed on the outside, giving the product an aesthetic appearance. The company has optimized the design of the transmission mechanism, ensuring compactness, synchronization and low contact jump.
Contactors are available in three versions: with electromagnetic latching, with mechanical latching and with magnetic latching, which allows you to select the most suitable type of drive depending on the operating conditions.
The mechanical locking mechanism is a patented development of the company. It provides stable and reliable switching on and off, is not subject to mechanical wear, has a long service life, low switching on and off current, and no power losses, which makes it an energy-saving product.
