Replaceable scale for ammeter E47 500/5A accuracy class 1.5 72x72mm IEK

The switches are designed for operation in electrical installations with voltages up to 660 V AC, frequency 50 and 60 Hz and up to 440 V DC for infrequent operational switching on and off of electrical circuits, as well as for protecting electrical equipment from overloads and short circuits. The series is designed for rated currents up to 2000 A. Depending on the type of current and voltage, it has a switching capacity of up to 135 kA. VA53-43 - current-limiting (application category A), with electromagnetic and electronic releases. VA55-43 – selective (application category B), with electronic releases. VA56-43 – without overcurrent releases.
