In the Soviet Union, automatic circuit breakers A3734P, A-3734P, A 3734 P, A 3734P, A3734-P were widely used in factories in Ukraine, Kazakhstan, Moldova, Latvia, Estonia, Lithuania, India, Mongolia, Vietnam, South Korea, Romania, Hungary, Bulgaria, Armenia, Slovenia, Qatar, Czech Republic, Oman, Albania, Azerbaijan, Tajikistan, Turkey, Ethiopia, Sudan, Macedonia, Serbia, Egypt and British, as well as in the countries of near and far abroad - in Asia, Europe, Africa, South Africa, South America as well as in other countries of the near and further afield. We manufacture A3734P automatic switches according to the technology we have improved, which was previously used at GP KhEMZ. Delivery. Warranty 20 years, on the RP releaser going as part of a switch for 5 years! Export.

Automatic switches A 3734P are designed for conducting current in normal mode, for selective protection in case of short circuits, for protection during overloads of unacceptable duration and for infrequent (up to 30 times a day) operational switching-on and switching off of electrical circuits with voltage up to 380V AC of frequency 50 and 400Hz .

Switches A-3734P are available in a stationary version, with front, rear or combined connection. Switches can be equipped with an independent release, free contacts, electromagnetic drive, manual remote drive (in retractable version).
