TECHNICAL DESCRIPTION: Circuit breakers A3723BU3, A3723BXL3, BA3723M, A3723BR, A3723BT3, BA3723, A3723S, A3723SXL3, VA3723SR, A3723ST3 are designed for conducting current in normal mode and protection during overloads of unacceptable duration, short circuits and unacceptable voltage drops, and also infrequent (up to 30 times per day) of operational disconnections of electrical circuits with a rated voltage of up to 660 VAC at 50 and 60 Hz and up to 440 VDC.
AC-3723 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 are manufactured in stationary and in retractable designs.
