Circuit breaker A3734SP

Sell and manufacturing of automatic switches А3734SP. The warranty is 20 years, on the release of the RP coming in the circuit breaker 5 years. In the Soviet Union, automatic circuit breakers A3734SP, A3734SP, A 3734 SP, A-3734SP (A3734CP, A3734CP, A 3734 CP, A-3734CP)were widely used in Ukraine, Kazakhstan, Moldova, Estonia, Latvia, Uzbekistan, Tajikistan, Bulgaria, Poland, India, South Korea and Turkey, as well as in the countries of near and far abroad. We manufacture the A3734SP automata according to the technology we have improved, which was previously used at GP KhEMZ. Export

Circuit breakers A3734SP are manufactured with three-pole in stationary version with front, rear or combined connection. Switches can be equipped with an independent release, free contacts, electromagnetic drive, manual remote drive.
