Circuit breaker A3715

Circuit breakers type A3715B, A3715P, A3715M, A3715BR, A3715BT3, VA3715, A3715F rated current up to 160 A. The circuit breakers A3715, 2 pole made constant and variable (50 Hz, 400) currents. Circuit breakers Circuit breakers are designed for 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 Frequency 50 and 60 Hz and 440 V DC. 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. The switches can be equipped with a shunt release, trip unit zero-voltage-free contacts, electromagnetic drive, manual remote drive (in withdrawable design).
