TECHNICAL DESCRIPTION: The VA3726, A 3726, A 3727 and A 3728 circuit breakers are designed to conduct current in normal mode and protect against overloads of unacceptable duration, short circuits and unacceptable voltage drops, and for infrequent (up to 30 times a day) operational cutoffs of electrical circuits with a rated voltage up to 660 In the AC frequency of 50 and 60 Hz and up to 440 VDC. Alternating current circuit-breakers can also be used for protection and infrequent direct starting of induction motors in the category of AC-3 applications.
Switches A-3726 are manufactured with thermal and electromagnetic maximum current releases, only with electromagnetic maximum current releases and without maximum current releases.
Switches can be equipped with an independent release, a zero-voltage release, free contacts and an electromagnetic drive.
Switches A3726BU3 are produced in stationary version - front, rear, combined connections and in retractable design. Switches can be equipped with an independent release, a zero-voltage release, free contacts, an electromagnetic drive, a manual remote drive (in retractable version).
