Circuit breaker VA04-36

Sale and production of circuit breakers VA04-36 of all types. Warranty 2 years! Ready-made products are always available for shipment.

Technical description: Automatic switches VA04-36 for rated current up to 400 A with electromagnetic, with thermal and electromagnetic releases. Circuit breakers VA-0436, VA04-36 2-pole are manufactured for constant and alternating current (Hz 50, 60). Automatic switches VA 0436, VA-04-36- 3-pole, are made on an alternating current.

Automatic circuit breakers VA0436 are designed to conduct current in normal mode and protect against overloads of unacceptable duration, short circuits and unacceptable voltage drops, as well as for infrequent, up to 20 times a day, operational disconnections of electrical circuits with a rated voltage of up to 660 V AC frequency 50 and 60 Hz and up to 440 VDC. AC automatic circuit breakers can also be used for protection and infrequent direct starts of asynchronous motors in the application category of AC-3. Circuit-breakers are produced by thermal and electromagnetic maximum releases, only with electromagnetic maximum current releases and without maximum current releases. The circuit breakers can be equipped with a zero-voltage release, an independent release, free contacts and an electromagnetic drive. Automatic are produced in a stationary version - front, rear and combined connection and in retractable design.
