At this time, it is possible to buy A3724 new ones only from RPE RIMK,LLC. In order to comply with the rules for operation and provide a guarantee circuit breakers are sealed. For the assembly of the A 3724 machines, all the technological processes that were used at GP KhEMZ were taken as the basis. In the delivery set there is always fasteners, visor, passport of the automatic switch A-3724. Full 3 year warranty! Sending A 3724B switches - DHL, Nova Poshta, Autolux, In Time, Delivery and other transport companies. We export switches to any country in the world!protection at overloads of inadmissible duration, at short circuits and inadmissible descents of a voltage, and also infrequent (up to 30 times a day) operational switching-off of electric circuits with nominal voltage up to 660 V AC frequency of 50 and 60 Hz and up to 440 VDC.
Switches A3724 are produced in a stationary version - front, rear, combined connections and in a retractable version. Switches can be equipped with an independent release, a zero-voltage release, free contacts, an electromagnetic drive, a manual remote drive (in retractable version).
