A3314M technical description: A3100 circuit breakers for rated current up to 100 A by electromagnetic releases and electromag-hydraulic releases. Circuit-breakers А3314 3-pole, are made on an alternating current.

Circuit breaker A3314 are designed to conduct current in normal mode and protect against overloads of unacceptable duration, short circuits and unacceptable voltage drops, as well as for infrequent, up to 20 times a day, operational tripping of electrical circuits with a rated voltage of up to 660 V AC 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 produced by thermal and electromagnetic maximum releases, only with electromagnetic maximum current releases and without maximum current releases. The circuit breakers can be equipped with an independent release, free contacts and an electromagnetic drive. Automatic are produced in stationary version - with front, rear and combined connection.
