VA55-43 Automatic Circuit Breakers for Reliable Electrical Safety

"KEAZ switches are designed for use in AC electrical circuits of frequency 50;60 Hz with voltage 690 V, for infrequent operational switching on and off (up to 6 per hour), specified circuits and protection of electrical equipment from overloads and short circuits, as well as not frequent direct start of induction motors
Switches are produced with semiconductor maximum current release on the basis of microcontroller Atmega 16L.
The range of rated currents 1600, 2000A"
