Switches are designed for operation in electrical installations with voltages up to 660 V AC at 50 and 60 Hz and up to 440 V DC for infrequent switching and disconnection of electrical circuits,
as well as for protecting electrical equipment from overloads and short circuits.
Series is designed for rated currents up to 2000 A.
Depending on the type of current and voltage magnitude, it has a breaking capacity of up to 135kA.
VA53-43 - current-limiting (application category A), with electromagnetic and electronic trip units.
VA55-43 – selective (application category B), with electronic trip units.
VA56-43 – without maximum trip units.
