Circuit breaker VA6333

Sale and manufacturing of automatic circuit breakers VA6333, the best prices for VA6333, fast delivery ВА6333.

Automatic circuit breakers VA6333 are designed for carrying out current in normal mode, for selective protection in case of short circuits, for protection during overloads of unacceptable duration and for infrequent (up to 30 times a day) operational switching-on and switching off of 380V or 660V AC circuits at 50 and 60Hz .

Switches of series VA6333 are produced in stationary version, three-pole.

Switches can be equipped with an independent release, free contacts, electromagnetic drive, manual remote drive. VA-6333 automatic machines are used on city electric trams, trolley buses and other.

The main technical characteristics of the switches:

1. Rated current, A 250.

2. Application category V.

3. Rated currents of semiconductor releases (RT), A: 63, 160, 200, 250.

4. Adjustable rated operating currents IR, A: -

5. Initial operating current in the zone of the overload currents, multiples of the rated operational current of the RP.

6. Setpoint according to the response time in the zone of overcurrent currents -

7. Settings for the response time in the zone of short-circuit currents-

8. Settings for the operating current in the zone of short-circuit current A: 160, 200, 250, 320, 400, 500, 630, 800, 1000, 1600

9. Rated short-time withstand current, kA 5.

10. Rated operating short-circuit breaking capacity, kA 7.5.

11. Wear resistance of switches:

a) the total number of cycles is 16,000.
