Sale and manufacturing of circuit breakers VA51-35 16A - 400A of all types in Europe. Selling automatic circuit breaker VA5135 in Ukraine. Export. Production the VA 51-35 250A, 200A, 160A, 400A, 320A, 125A, 100A, 80A, 63A, 50A, 40A, 32A, 31,5A, 25A, 20 A, 16A, 12,5A, 10A (AC/DC) in Ukraine.

Technical description: Automatic circuit breakers VA5035 for rated current up to 400 A with electromagnetic, with thermal and electromagnetic releases. Automatic switches VA-5135, VA52-35 2-pole are manufactured for constant and alternating current (Hz 50, 60). Circuit breakers VA 5135, VA 5235- 3 pole, are made on an alternating current.

Automatic switches VA5135 are designed to conduct current in normal mode and protect against overloads of unacceptable duration, in case of short circuits and unacceptable voltage drops, as well as for infrequent, up to 20 times a day, operational trips of electrical circuits with rated voltage 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.

Technical characteristics of circuit breakers VA 5135:

1. Rated current 400A.

2. Number of poles 2; 3.

3. Rated currents of thermal releases up to 400A.

4. Setting for the initial pick-up current in the zone of the overload currents, multiples of the rated current of the thermal trip unit 1.3.

5. Settings for the current tripping of electromagnetic maximum current releases up to 4000A.

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 cycles of VO under load 1000.

8. Weight (stationary version) - 2.1 kg.
