Sale of circuit breakers VA554-41 and VA56-41 for rated current, А 250, 400, 630, 800, 1000, 1250. Always in stock all executions! Sell automatic switch BA5541 in Europe. Export the automatic switches VA 55-41, VA 56-41 1000A 3P, 2P in Europe.

Technical description: Circuit breakers VA50-41 for rated current up to 1000 A are equipped with semiconductor, microprocessor and electromagnetic releases. Circuit breakers VA50-41 2-pole are manufactured for constant and alternating currents (Hz 50, 60). Circuit-breakers VA50-41 3-pole, are made on an alternating current.

Automatic circuit breakers are designed to conduct current in normal mode and protect against overloads of unacceptable duration, with short circuits and unacceptable voltage drops, and for infrequent, up to 20 times a day, operational tripping of electrical circuits with a rated voltage of up to 660 VAC of 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 minimum 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.

Technical characteristics of circuit breakers VA50-41:

1. The rated current is 1000A.

2. Number of poles 2; 3.

3. Rated currents of semiconductor releases A, 250, 400, 630, 800, 1000, 1250

4. The setting for the initial pickup current in the zone of the overload currents, a multiple of the rated current of the release 1.25.

5. Settings for the current of operation of electromagnetic maximum current releases up to 10000A.

6. Rated operating short-circuit breaking capacity, kA: at a rated voltage of 380 V AC 25, at a nominal voltage of 660 V AC 19, at a nominal voltage of 440 VDC 50.

7. Wear resistance of circuit breakers - total number of cycles of VO 3000, number of VO cycles under load 1500.

8. Weight (stationary version) - 27,8 kg.
