Circuit breaker A3785P

Sale and manufacturing of automatic switches A3785P 200A, 250A, 160A 440V DC, ~380В-400V 50-400Hz. Warranty 20 years! Always available! Export the A-3785P circuit breaker.

Automatic switches A3785P are intended for carrying out of a current in a normal mode and protection at overloads of inadmissible duration, at short circuits and inadmissible decrease in pressure, and also for infrequent (up to 30 times a day) operative disconnections of electric circuits with a rated voltage up to 660 V of a frequency 50 and 60 Hz and up to 440 VDC. A-3785P 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 3785P are available with thermal and electromagnetic maximum current releases.

Switches can be equipped with an independent release, free contacts and an electromagnetic drive.

Switches are manufactured in stationary version.
