Always the best price in Ukraine - it is favorable to buy A 3791M! With the union, automatic circuit breakers A-3791M, A 3791M, A3791 M, A 3791 M were widely used in Ukraine, Moldova, Latvia, Estonia, Lithuania, India, Mongolia, Vietnam, Korea, Romania, Hungary, Bulgaria, Armenia, South Africa, Poland, Czech, Pakistan, Sudan, Egypt and Kazakhstan, as well as countries of near and far abroad, in Asia, Europe, Africa, South America, the Middle East and Korea. We manufacture the A3791M circuit breaker using the technology we have previously improved, which was previously used at GP KhEMZ. Warranty 15 years. Delivery of circuit breakers to any country in the world. Sending automat A 3791M is made by transport companies. Circuit breakers A3791M are manufactured since 1985 and have proven themselves well.

Automatic switches A3791M high-speed, for use on ships with any radius of voyage (vibro and shock-resistant) are designed to conduct current in normal mode, for selective protection in case of short circuits, for protection during overloads of unacceptable duration and for infrequent operational switching-on and off of electrical circuits voltage 380V or 660V AC frequency of 50 and 400Hz.

Switches A3791M TU16-522.159-84 are produced bipolar in stationary version, for alternating and direct currents. Switches can be equipped with an independent release, free contacts, electromagnetic drive, manual remote drive.
