Air switches VA-450 PROxima, etc.

Automatic switches VA-45 to 6300A PROxima
Circuit breakers of the BA-45 PROxima series are air switches with a mechanism for free release and operation of contacts by means of a mechanism with a spring energy storage. Structurally, the switch is made in the form of a mechanical structure mounted on a rigid frame.The main controls and displays are displayed on the front panel.A complete set of accessories to expand the functions.

Automatic switches VA-450 to 1600A PROxima
Circuit breakers of the BA-450 PROxima series with microprocessor control for rated currents from 200 to 1600 A are designed to protect low-voltage AC power grids (up to 690V) from overload and short-circuit currents, including with time delay (selective switches), operational switching on and off of networks when controlled directly by the operator, or by command signals of the automatic control system for the distribution of electrical energy, in which a switch is installed, to turn off the network in case of a decrease in the mains voltage below the permissible or the voltage disappears.

Automatic switches VA-450 to 1000A PROxima
The BA-450 PROxima is designed to protect low-voltage AC power grids (up to 690V) from overload and short-circuit currents, including with time delay (selective switches), as well as for operational switching on and off of networks manually or remotely.
