Circuit breaker A3711, VA3711

Circuit breaker A3711, VA3711.
Breaker A3711U. Datasheet: A3710 Circuit breakers with rated current up to 160 A with semiconductor, thermal-magnetic trip units. Circuit breakers A3711, A3713, A3715, A3717- 2 pole made constant and variable (50 Hz, 400) currents. Circuit breakers A3712, A3714, A3716, A3718- 3 pole, made on an alternating current (50 Hz, 400).
The circuit breakers are designed to carry current in normal operation and protection in case of overload unacceptable duration, short-circuit, and undervoltage, as well as for infrequent, up to 30 times a day, operating off electrical circuits with a nominal voltage up to 660 V AC, 50 Hz and 60 Hz and up to 440 VDC. Circuit Breakers AC can also be used to protect and infrequent straight starts asynchronous motors in utilization category AC-3. The circuit breakers are produced with semiconductor releases, semiconductor and electromagnetic overcurrent release, with thermal and electromagnetic overcurrent release, only with electromagnetic current releases and without overcurrent releases. Circuit breakers can be equipped with a zero-voltage shunt trip, shunt trip-free contacts and an electromagnetic drive. Circuit breakers are available in fixed version - front, rear and combined connection and withdrawable design.
