Export. Automatic circuit breakers are designed to conduct current in normal mode and protect against overloads of unacceptable duration, with short circuits and unacceptable voltage drops, and for infrequent, up to 30 times a day, operational tripping of electrical circuits with a rated voltage of up to 660 VAC of frequency 50 and 60 Hz and up to 440 VDC. AC automatic circuit breakers can also be used for protection and infrequent direct starts of asynchronous motors in the application category of AC-3. Circuit-breakers are manufactured with semiconductor releases, with semiconductor and electromagnetic maximum releases, with thermal and electromagnetic maximum current releases, only with electromagnetic maximum current releases and without maximum current releases. The circuit breakers can be equipped with a zero-voltage release, an independent release, free contacts and an electromagnetic drive. Circuit-breakers are available in stationary version - front, rear and combined connection and in retractable design.
Switches are manufactured in stationary and in retractable designs.
Switches can be equipped with an independent release, a zero-voltage release, free contacts, an electromagnetic drive, a manual remote drive (in retractable version).
