TECHNICAL DESCRIPTION: A3732 circuit-breakers are designed to conduct current in normal mode and to protect against overloads of unacceptable duration, short circuits and unacceptable voltage drops, and for infrequent (up to 30 times a day) operational disconnections of electrical circuits with a nominal voltage of up to 660 V ( VA3730U to 1140V) of alternating current of frequency 50 and 60 Hz and up to 440 V of direct current.

AC-3732 circuit breakers can also be used for protection and infrequent direct starting of induction motors in the category of AC-3 applications.

Switches A 3732 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 A-3732 are produced in a stationary version - front, rear, combined connections and in a retractable version.
