General purpose industrial circuit breakers A3700

Automatic switches A3700 are designed to conduct current in normal mode and disconnect current during overloads, short circuits and unacceptable voltage drops, as well as for infrequent operational switching of circuits with rated voltage (depending on the version); up to 440 V DC; up to 660 V AC frequencies of 50 and 60 Hz; up to 380 VAC of 400 Hz frequency (A3790 switches at 400 Hz are not designed). Circuit breakers A3700 HEMZ common industrial purpose for the needs of energy in Ukraine, Belarus, Russia, Moldova, Bulgaria, Romania, Lithuania, Estonia, Latvia, Mongolia, Korea, India, Vengia, Czech Republic, Slovakia, Slovenia, Poland, Mongolia, Vietnam, China, South Africa, Egypt, Kazakhstan, Armenia, Azerbaijan, Georgia, Turkey, Algeria, Sudan, Nigeria, Iraq and other countries in Europe, Asia, the Middle East. Automatic switch series - A3791, A3792, A3793, A3794, A3795, A3796, A3797, A3798, A3711, A3712, A3713, A3714, A3715, A3716, A3717,A3718, A3721, A3722, A3723, A3724, A3725, A3726, A3727, A3728, A3771, A3772, A3775, A3776, A3777, A3778, A3781, A3782, A3785, A3786, A3787, A3788, A3731, A3732, A3733, A3734, A3735, A3736, A3737, A3738, A3741, A3742, A3743, A3744, A3747, A3748.  Depending on the design, the overcurrent releases are used in the circuit breakers: electromagnetic and semiconductor, thermal and electromagnetic, only semiconductor. There are switches without overcurrent releases (non-automatic). Circuit breakers A3710B, A3720B, A3790B, A3790C, A3790N are manufactured in a fixed and withdrawable design by the method of installation.
