TECHNICAL DESCRIPTION: The A-3722 circuit breakers are designed to conduct current in normal mode and protect against overloads of unacceptable duration, short circuits and unacceptable voltage drops, as well as infrequent (up to 30 times a day) operational disconnections of electrical circuits with a rated voltage of up to 660 V (VA3720U to 1140V) of alternating current of frequency 50 and 60 Hz and up to 440 V of direct current.
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 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 A3722 are produced in stationary version - front, rear, combined connections and in retractable design.
